1	IMb Tracing™:  A Summary
1-1	Background
IMb Tracing™ is the successor to the legacy Confirm Service.  It should be noted that references to the Confirm Service may still exist during the transition period.  To avoid confusion, these terms should be considered interchangeable.
PLANET Code scan events are not available through the IMb Tracing™ service.  However, until all existing Confirm subscriptions expire, they will still be available through the legacy Confirm service.
1-2	Description
IMb Tracing™ allows mailers to uniquely identify and receive mail processing data for outgoing and incoming reply mailpieces. It provides mailers with information about automation-compatible letters and flats for First-Class Mail®, Standard Mail®, and Periodicals mail. Data includes the date, time, location and sort operation of a mailpiece processed at a Postal Service facility.
IMb Tracing™ requires that mailers display prescribed Intelligent Mail™ on the front of mailpieces. A mailer’s proper application of these barcodes allows the Postal Service to generate IMb Tracing™ scan data and distribute this data to the mailer.
IMb Tracing™ provides two types of service: Destination IMb Tracing™ and Origin IMb Tracing™.
1-2.1	Destination IMb Tracing™
Destination IMb Tracing™ can provide mailers with mailpiece processing data that helps them determine delivery.
1-2.2	Origin IMb Tracing™
Origin IMb Tracing™ enables the IMb Tracing™ mailer to determine when and where their customers mailed incoming reply mailpieces. Remittance mail processors and mail order companies use Origin IMb Tracing™ to receive advance notice of incoming payments and orders.
1-3	
How IMb Tracing™ Works: Process Overview
IMb Tracing™ uses barcodes scanned by mail processing equipment to collect data from mailpieces as they are sorted and approach delivery.
Prior to using IMb Tracing™, the mailer must become an IMb Tracing™ subscriber. Refer to chapter 2 for steps required to subscribe to the service. Upon establishing an IMb Tracing™ account, mailers follow the IMb Tracing™ process as noted below:
a.	Mail planning and preparation.
b.	Mail processing at a Postal Service facility.
c.	Data access and interpretation.

1-3.1	Mail Planning and Preparation
a.	The mailer decides whether to use Destination IMb Tracing™, Origin IMb Tracing™, or both.
b.	The mailer determines the information to be include within the IMb™.  This includes using a Service Type ID which requests IMb Tracing™ on the mailpieces for which the mailer wishes to receive tracking data.
c.	The mailer ensures that mailpieces are designed and prepared in accordance with IMb™ requirements and basic specifications for automation-compatible mail.
d.	The mailer prepares mail to be inducted at a Postal Service facility.
Refer to chapter 3 for detailed information. 
1-3.2	Mail Processing at a Postal Service Facility
a.	The Postal Service processes the mailpieces on mail processing equipment (MPE). IMb Tracing™ data is generated each time that a “machine-readable” IMb mailpiece is sorted using automated MPE. Mailpieces that are not processed on MPE do not generate IMb Tracing™ scan data. 
b.	Mailpiece scan data contains processing location, sort operation, date/time, and barcode digits.
Refer to chapter 4 for detailed information.
1-3.3	Data Access and Interpretation
a.	The mailer receives mailpiece scan data from the Postal Service. Options are either to receive data electronically via scheduled file transfer, or to download the data from the Mail Tracking and Reporting website at http://mailtracking.usps.com.
b.	The mailer integrates and utilizes IMb Tracing™ data to suit their business needs. The mailer references support resources (e.g., Operation Code listing) to help interpret the data and turn it into useful information. In most cases, data can indicate mail delivery dates with a high level of certainty.
Refer to Chapter 5 for detailed information.
1-4	Applications and Potential Benefits
Destination IMb Tracing™ is used by mailers to anticipate when their message will reach their customers.  Origin IMb Tracing™ is used to gain insight into when a customer’s response is on the way to the mailer. Mailers can use IMb Tracing™ to align their business processes and resources with the actual processing and delivery status of their mail.  Integrating IMb Tracing™ data into current business practices puts valuable information into the hands of corporate decision makers, which could help to reduce costs, enhance marketing efforts and improve relationships with customers.

3-6	Intelligent Mail Barcode Print Requirements
Barcodes should be printed in accordance with DMM 708.4 (http://pe/text/dmm300/708.htm#1352817).
 Please refer to the Intelligent Mail Barcode specification document (https://ribbs.usps.gov/intelligentmail_mailpieces/documents/tech_guides/SPUSPSG.pdf) for more detailed information on the following tracking code print requirements:
a.	Address block.
b.	Barcode pitch.
c.	Bar dimensions.
d.	Barcode tilt.
e.	Baseline shift.
f.	Reflectance.
g.	Ink Issues (overinking and voids).
Complying with the Intelligent Mail barcode specifications increases the likelihood that mail processing equipment will accurately read the information present on barcoded mailpieces. Non-compliance with these specifications will have an adverse impact on the number of scans the mailer receives from IMb Tracing™ mail.
4	IMb Tracing™ Mail Processing Data
4-1	Scanning IMb™ Mailpieces
IMb Tracing™ provides scan data that reflects automated processing of subscribers’ mail containing Intelligent Mail barcodes. When the Postal Service processes IMb™ barcoded mail on high-speed mail sorting equipment, comma-delimited raw scan data records are created.  The mailpiece scan record represents where, when, and at which operation level an individual mailpiece is processed. 
A mailpiece is likely to generate multiple mailpiece scan records as it is processed on automated equipment prior to delivery. However, the Postal Service cannot guarantee that every IMb Tracing™ mailpiece with an IM™ barcode will receive a scan or multiple scans.
4-2	IMb Tracing™ Mailpiece Scan Data Record Format
The following table outlines the current layout of the IMb Tracing™ scan data record.  The file will always be in fixed width and comma delimited format.

The scan records that are produced during sort operations allow customers to interpret the data and estimate when mailpieces are near delivery.

5	Data Access and Interpretation
5-1	Data Access
IMb Tracing™ scan data is created each time IMb mailpieces with an IMb Tracing Service Type ID are sorted on mail processing equipment.  Refer to chapter 4 for details on the scan data record format.
Mailers can receive mailpiece scan data in two ways:
a.	File transfer protocol (FTP)
b.	Download from the IMb Tracing™ website
5-1.1	FTP (File Transfer Protocol)
Customers provide their Internet protocol (IP) and host information to be entered into their account by the IMb Tracing™ Customer Support staff.  This allows scan data to be sent to the customer on a set download schedule of their preference.  Customers receive scans accumulated since the last scheduled upload — up to 24 times a day for mailpiece scan data files.  All data will be included in a package file with a “pkg” file extension.
5-1.2	Mail Tracking and Reporting website
Subscribers can download their raw scan data from the IMb Tracing™ section of the Mail Tracking and Reporting website at http://mailtracking.usps.com.
5-2	Managing Scan Data Notification Schedules and Contact Information
To receive mailpiece scan data, subscribers must provide the helpdesk with the contact information and the desired notification schedule(s)
Subscribers can enter and maintain the information necessary to manage scan notifications at the Mail Tracking and Reporting (MT&R) website at http://mailtracking.usps.com.
a.	In the Contact Setup section, subscribers can enter and maintain contact information for e-mail and file transfer notification.
b.	In the Host Setup section, subscribers can enter and maintain host information for FTP notification.
c.	In the Mailpiece Scan Schedule section, subscribers can select how and when to receive IMb Tracing™ notifications and view notification history.
For assistance, contact IMb Tracing™ Customer Support via email at IMbTracing@usps.gov.
5-3	Scan Data Interpretation
When interpreting scan data, it is important to remember that an IMb Tracing™ mailpiece will most likely receive more than one scan. Multiple scans of a mailpiece make it possible to determine processing time and location of each mailpiece.  By evaluating mailpiece processing scans, mailers get an indication of when their mailpieces are near delivery. 
Mailpiece Scans. The four subsequent scans shown in Exhibit 5-5 represent mailpiece scans. Mailpieces can be uniquely identified by using the Intelligent Mail barcode. A mailpiece scan history can be used to interpret mail processing and evaluate delivery.

5-3.1	Postal Service Sort Operation Codes
Each IMb Tracing™ scan data record includes a 3-digit sort operation code.  Mailers use operation codes to determine the processing status of mailpieces.  Understanding these Postal Service operation numbers is critical to the interpretation of IMb Tracing™ scan data.  
Each IMb Tracing™ mailpiece will likely generate multiple mailpiece scan records, each of which will contain a different sort operation code representing a type of sort operation.  The number and type of sort operations that take place will depend on numerous factors, including mail class, shape, presort level, and originating and destinating locations.
Each sort operation code provided by IMb Tracing™ scan data represents a type of sortation and the type of equipment on which the mail was processed.  Each type of sortation process may be represented by multiple sort operation codes, depending on the type of system on which processing took place.
To obtain the most current list, go to the MT&R website at http://mailtracking.usps.com; logon to the website as an “Existing User”; click on IMb Tracing™; then click on IMb Tracing™ Resources; and then click on IMb Tracing™ Reference Data Tables.
Below are definitions of some of the major process types.
a.	Outgoing (O/G) Primary: Originating mail separated by automated area distribution center (AADC), 3-digit ZIP Code separations, and 5-digit ZIP Code separations for overnight, 2-day, and 3-day delivery. Additional processing is required on automated equipment. The last digit of this 3-digit operation code generally ends with “1.”
b.	Outgoing (O/G) Secondary: Originating mail not finalized on outgoing primary separated by AADC, 3-digit ZIP Code separations, and 5-digit ZIP Code separations for overnight, 2-day, and 3-day delivery. Additional processing is required on automated equipment. The last digit of this 3-digit operation code generally ends with “2.”
c.	Managed Mail: 3- and 5-digit outgoing primary mail normally sorted from an AADC level down to 3-digit ZIP Code level, with high-volume 5-digit zones and firms also held out. Additional processing is required on automated equipment for the 3-digit sorted volume and the 5-digit sorted volume for which the plant has incoming secondary, delivery point sequence (DPS), sector/segment, or box section sorting responsibility. The last digit of this 3-digit operation code generally ends with “3.”
d.	Incoming (I/C) SCF (sectional center facility): Local destinating mail normally separated by the host SCF by 5-digit ZIP Code. Additional processing on automated equipment is required for the 5-digit ZIP Codes for which the plant has incoming secondary, DPS, sector/segment, or box section sorting responsibility. The automated zone indicator (AZI) table (see 7-5.3.2.) provides more detailed information about processing for each ZIP Code. The last digit of this 3-digit operation code generally ends with “4.”
e.	Incoming (I/C) Primary: Local mail normally separated by the host SCF by 5-digit ZIP Code for which it has delivery responsibility. Additional processing on automated equipment is normally required for mail for which the plant has incoming secondary, DPS, sector/segment, or box section sorting responsibility. The AZI table provides more detailed information about processing for each ZIP Code. The last digit of this 3-digit operation code generally ends with “5.”
f.	Incoming (I/C) Secondary: Local mail normally separated by carrier route. This mail might be finalized, or additional processing might be required for letter mail on automated equipment (e.g., carrier sequence barcode sorters). This is the final processing for flats. The last digit of this 3-digit operation code generally ends with “6.”
g.	Box Section: Local mail normally separated by Post Office box section. In most instances, this is the final automated processing for this mail (manual sorting is required to separate mail by individual Post Office box). In some instances, mail is separated into individual Post Office boxes by repeating this operation on automated equipment. This is the reason why mailers may receive multiple scans with the same operation code for a given piece. The last digit of this 3-digit operation code generally ends with “7.”
h.	Sector/Segment (SEC/SEG or S/S): Mail that typically requires two passes to complete:
(1)	1st Pass. Mail normally separated by ZIP + 4® sectors. This mail requires additional processing on automated equipment. The last digit of this 3-digit operation code generally ends with “8.”
(2)	2nd Pass. Mail normally separated by ZIP + 4 segments. This is the final processing of mail. The last digit of this 3-digit operation code generally ends with “9.”
i.	Delivery point sequence (DPS): Mail that is sorted into carrier walk sequence. These sorts often require two passes to complete:
(1)	1st Pass. In most cases, this mail requires additional processing on automated equipment. This is the last processing for some mailpieces (e.g., firm holdouts, box sections, and Postal Service facilities). The last digit of this 3-digit operation code generally ends with “8.”
(2)	2nd Pass. Final processing of mail. The last digit of this 3-digit operation code generally ends with “9.”
5-3.2	Evaluating Delivery
5-3.2.1	Overview
There are several factors to consider when evaluating the delivery date and performance of IMb Tracing™ mailpieces.  Mailers can evaluate delivery by the following factors:
a.	Identifying stop-the-clock operation codes that are often the final mailpiece scans on individual mailpieces.
b.	Becoming familiar with and utilizing the days-in-system calculation.
5-3.2.2	Stop-the-Clock Operation Codes
Sort operation codes can be useful in determining delivery dates of mailpieces.  The Postal Service has identified certain sort operation codes that qualify as stop-the-clock operations.  These codes represent operations recognized by the Postal Service to help indicate same-day delivery with a high level of certainty.  As a guideline, when mailpieces generate IMb Tracing™ scan records containing one of these codes prior to the corresponding cut-off time and this is the last scan that occurs on the mailpiece, there is a very strong likelihood that the mailpiece will be delivered that same day. Not all mailpieces receive stop-the-clock scans as the final scan.  
For a current listing of Stop-the-Clock Operation Codes and their associated ‘cut-off’ times, refer to the Operation Codes list.  To obtain the most current list, go to the MT&R website at http://mailtracking.usps.com; logon to the website as an “Existing User”; click on IMb Tracing™; then click on IMb Tracing™ Resources; and then click on IMb Tracing™ Reference Data Tables.
5-3.2.3	Days-in-System Calculation
The Postal Service commonly uses the days-in-system calculation to determine the number of days it takes the Postal Service to deliver the mail from induction to delivery.  In order to obtain the first scan date, mailers must submit electronic documenation which will also enable free start-the-clock tracking data through PostalOne!.  This calculation considers that no deliveries are made on Sundays or holidays.  Exhibit 5-5.2.3 shows the days-in-system calculation.
Exhibit 5-5.2.3
Days-in-System Calculation
Days in System = (Last Scan Date – First Scan Date) – (Adjustment for Sunday/Holiday)	

The adjustment for Sunday/Holiday is determined using the following logic:
a.	If the last scan date falls on a day immediately following a Sunday or holiday, then subtract 1 from the days-in-system value.
b.	If the last scan date falls on a day immediately following a Sunday, and that Sunday is immediately preceded by a holiday, then subtract 2 from the days-in-system value.
c.	If the last scan date falls on a day immediately following a holiday, and that holiday is immediately preceded by a Sunday, then subtract 2 from the days-in-system value.
d.	If the last scan date falls on a day immediately following a Sunday, and that Sunday is immediately preceded by two consecutive holidays, then subtract 3 from the days-in-system value.
e.	If the last scan date falls on a day immediately following a holiday, and that holiday is immediately preceded by two consecutive holidays (or a holiday and a Sunday), then subtract 3 from the days-in-system value.
5-3.3	Scan Expectations and Related Resources
IMb Tracing™ scan data reflects the automated processing of mailpieces; however, due to the nature of mail processing there is no guarantee that a mailpiece will receive a scan. When a mailpiece does receive a scan, there are several factors such as shape, presort level, and destinating zone that impact overall scan performance.  These factors should be considered when interpreting scan data.
5-3.3.1	Letter Mail Processing
Letter mail barcoded with tracking codes is more likely than flat mail to generate IMb Tracing™ scan data.  To be eligible for scanning, letter mail must first adhere to basic mailpiece design specifications for automation-compatible mail. Proper barcodes must be present on the front of the mailpieces.
5-3.3.1.1	Automated Zone Indicator (AZI) Table
The automated zone indicator (AZI) table (see Exhibit 7-5.3.2) lists all 5-digit ZIP Codes and is an indicator of the type of processing that typically takes place on IMb Tracing™ letter mail destined for those ZIP Codes.  The AZI is formatted in an Excel spreadsheet and contains all Postal Service 5-digit ZIP Codes, each of which is assigned one numeric zone indicator. The five numeric indicators are as follows:
1.	Two Pass Zones: Automated two-step sector/segment at mail processing facilities.
2.	876 Carrier Route Sort Zones: Automated incoming secondary carrier route sorting at plants.
3.	Carrier Route Barcode Sorter (CSBCS) Zones: Automated walk sequence sorting on CSBCS machines at delivery units.
4.	Delivery Barcode Sorter (DBCS) Zones: Automated walk sequence sorting on DBCS machines at plants (i.e., SCFs) or at delivery units.
5.	Manual/Mechanized Zones: No automated sorting. No tracking code scans should be generated from facilities matched to these ZIP Codes.

Note: The AZI table is maintained and updated by the Postal Service’s Address Management Services. The Postal Service posts an updated version of this table on the MT&R website at http://mailtracking.usps.com; logon to the website as an “Existing User”; click on IMb Tracing™; then click on IMb Tracing™ Resources; and then click on IMb Tracing™ Reference Data Tables.
A subscriber’s scan expectancy on letter mail depends on the type of zone for which the mailpiece is destined, along with the presort level in which the mail was prepared.  For example, letter mail presorted to a 3-digit level is more likely to receive mailpiece scans than mail presorted to a finer sort level (e.g., 5-digit presort) because the 3-digit sort mail requires more automated sorting to prepare it for delivery.
Some general guidelines regarding scan expectancy using AZI are the following:
a.	Letter mailpieces presorted at 5-digit level and destined to AZI 5 zones should not receive mailpiece scans.
b.	Letter mailpieces destined to AZI zones 1 and 5 should not receive stop-the-clock scans. There is also a low likelihood that letter mailpieces destined to AZI zone 2 will receive stop-the-clock scans.
c.	Letter mailpieces destined to AZI zone 3 may receive a stop-the-clock scan if they are processed on delivery point sequence (Operation Number 905) at the Postal Service delivery unit.
d.	Letter mailpieces destined to AZI zone 4 are most likely to receive mailpiece scans.  These pieces should receive a stop-the-clock scan.
5-3.3.2	Flat Mail Processing
Customers report that they typically receive lower IMb™ scan rates on flats than on letter mail. This is largely attributed to the following reasons:
a.	A notable amount of flat mail bypasses processing equipment and does not get scanned.  The Postal Service does not process flat size mail on automated equipment for 5-digit ZIP Codes that have fewer than ten carrier routes, that do not have sufficient densities to meet automation processing thresholds, or that cannot be processed on automation processing equipment to meet delivery schedule windows.  In these situations, the standard operating procedure in the field is to send 5-digit bundles directly to delivery units.
Note: All carrier route bundles always bypass automation and therefore do not receive scans.
b.	A number of smaller plants do not have automated flats equipment, so 3-digit and 5-digit presorted mail for their service areas are not scanned.  Most basic presorted mail for these areas receive a scan “upstream.”
IMb Tracing™ is relevant only for automation-rate mailings.
For individual mailings, however, the expected scan rate depends on the destination area and on the portion of the mailing that is 5-digit presorted.  For some mailings, the expected scan rate could be 80 percent or more, while for others it could be substantially below 60 percent.  To enable mailers to predict and evaluate scan rates for their individual mailings (or for ZIP Code areas), the Postal Service provides IMb Tracing™ subscribers with location-specific information tables. To ensure accuracy of these tables, please report any anomalies noted in the lists to IMb Tracing™ Customer Support via email at IMbTracing@usps.gov.
With information from the tables, both mailers and the Postal Service will be better able to evaluate whether the scan rate for a particular mailing or area is about what would be expected, or is sufficiently below expectations and indicates a need for further investigation.
5-3.3.2.1	Nonautomated SCF Table
The nonautomated SCF table is available to help IMb Tracing™ customers determine where to expect mailpiece scans on flat mail.  Flat mailpieces with IMb Tracing™ barcodes, presorted at the 3-digit or 5-digit level, destined for the 3-digit ZIP Code zones in this table are likely not to receive scans.
The nonautomated SCF table lists all 3-digit ZIP Code zones where flat mail is not processed on automated barcode sorting equipment.  The nonautomated SCF table is formatted in an Excel spreadsheet and contains four data fields:
a.	SCF: The Postal Service 3-digit ZIP Code representing an SCF.
b.	Site: The SCF name (usually associated with a city).
c.	State: The state in which the SCF is located.
d.	Associated 3-digit ZIPs: The Postal Service 3-digit ZIP Codes associated with the SCF.
Exhibit 5-5.3.3.1 shows a sample nonautomated SCF table.

5-3.3.2.2	Nonautomated 5-Digit ZIP Code Table
The nonautomated 5-digit ZIP Code table is available to help IMb Tracing™ customers determine where to expect mailpiece scans on flat mail.  Flat mailpieces with IMb Tracing™ barcodes — presorted at the 5-digit level — destined for the 5-digit ZIP Code zones in this table are likely not to receive scans.  Flat mail presorted to the 3-digit level may receive scans “upstream” if mail is destined to an automated SCF.
The nonautomated 5-digit ZIP Code table lists all 5-digit ZIP Code zones where flat mail is not processed on automated barcode sorting equipment.  The nonautomated 5-digit ZIP Code table is formatted in an Excel spreadsheet and contains three data fields:
a.	ZIP: The Postal Service 5-digit ZIP Code.
b.	City: The city associated with the ZIP Code.
c.	State: The state in which the ZIP Code and city are located.

5-3.4	Scan Performance Guidelines
The following rules should be considered when determining scan performance for IMb Tracing™ letters and flats.
5-3.4.1	Letters
5-3.4.1.1	First-Class Mail
a.	Automation Mixed AADC and Automation AADC. Typically, letter mail in these categories will be processed on automation equipment.
b.	Automation 3-Digit. Typically, letter mail in this category will be processed on automation equipment, with the exception of a limited number of nonautomated SCFs, especially if the mail is dropped and destined at the nonautomated SCF.
c.	Automation 5-Digit. Typically, letter mail in this category destined to AZI 5 zones (i.e., manual zones) will not be processed on automation equipment; however, letter mail destined to all other zones will be processed on automation equipment. In some instances, letter mail destined to AZI 2 zones (i.e., 876 carrier route sort zones) may be processed on multiline optical character reader (MLOCR) equipment (which does not include IMb Tracing™ barcode read capability) and therefore will not be scanned. Use the AZI table to help determine scan expectations.
d.	Automation Carrier Route. This category of mail is available only for AZI 3 zones (i.e., CSBCS zones) and AZI 5 zones (i.e., manual zones). Typically, mail that is processed in AZI 3 zones will be processed on CSBCS processing equipment. Mail that is destined for AZI 5 zones typically will not be processed on automation equipment.
e.	Nonautomation Single-Piece. Typically, letter mail in this category will be processed on automation equipment. These pieces are first processed through an automated facer-canceler and are then routed to a barcode sorter.
f.	Nonautomation Presorted. Nonmachinable letters (including “Manual Only”) in this category will not receive a scan. Use the information above to determine the likelihood of scans for machinable letters within this category at the various presort levels.
Note: Automation Mixed AADC and nonautomation single-piece are only originating operations.
5-3.4.1.2	Standard Mail
a.	Automation Mixed AADC and Automation AADC. Typically, letter mail in these categories will be processed on automation equipment.
b.	Automation 3-Digit. Typically, letter mail in this category will be processed on automation equipment, with the exception of a limited number of manual SCFs, especially if the mail is dropped and destined at the nonautomated SCF.
c.	Automation 5-Digit. Typically, letter mail in this category destined to AZI 5 zones (i.e., manual zones) will not be processed on automation equipment; however, letter mail destined to all other zones will be processed on automation equipment. In some instances, letter mail destined to AZI 2 zones (i.e., 876 carrier route sort zones) may be processed on MLOCR equipment (which does not include IMb Tracing™ barcode read capability) and therefore will not be scanned. Use the AZI table to help determine scan expectations.
d.	Enhanced Carrier Route (ECR) High Density and ECR Saturation. Typically, letter mail prepared for these categories will not be processed on automation equipment. However, in some instances, mail destined for AZI 3 zones (i.e., CSBCS zones) and AZI 4 zones (i.e., DBCS zones) may be processed on automation equipment.
e.	ECR Automation Basic. This category of mail is available only for AZI 3 zones (i.e., CSBCS zones) and AZI 5 zones (i.e., manual zones). Typically, mail that is processed in AZI 3 zones will be processed on CSBCS processing equipment. Mail that is destined for all AZI 5 zones typically will not be processed on automation equipment.
f.	ECR Basic. Typically, letter mail prepared for these categories will not be processed on automation equipment due to the physical characteristics of these mailpieces. The rate for this category is higher than the rate for 5-digit automation letters; therefore a majority of the pieces in this category do not meet the specifications for automation.
g.	Presorted Basic. Typically, letter mail in this category will be processed on automation equipment. (This is mixed AADC and AADC, so it should be scanned.)
h.	Presorted 3/5. Typically, letter mail in this category destined to AZI 5 zones (i.e., manual zones) will not be processed on automation equipment; however, letter mail destined to all other zones will be processed on automation equipment. In some instances, letter mail destined to AZI 2 zones (i.e., 876 carrier route sort zones) may be processed on MLOCR equipment (which does not include IMb Tracing™ barcode read capability) and therefore will not be scanned. The 3-digit sorted pieces will typically be processed on automation equipment, with the exception of a limited number of manual SCFs, especially if the mail is dropped and destined at the nonautomated SCF. Use the AZI table to help determine scan expectations for the 5-digit sorted pieces.
Note: Automation Mixed AADC is only an originating operation.
5-3.4.1.3	Periodicals
a.	Nonautomation/Automation Basic. Typically, machinable letter mail in these categories will be processed on automation equipment.
b.	Nonautomation/Automation 3-Digit. Typically, letter mail in this category will be processed on automation equipment, with the exception of a limited number of nonautomated SCFs, especially if the mail is dropped and destined at the nonautomated SCF.
c.	Nonautomation/Automation 5-Digit. Typically, letter mail in this category destined to AZI 5 zones (i.e., manual zones) will not be processed on automation equipment; however, letter mail destined to all other zones will be processed on automation equipment. In some instances, letter mail destined to AZI 2 zones (i.e., 876 carrier route sort zones) may be processed on MLOCR equipment (which does not include IMb Tracing™ barcode read capability) and therefore will not be scanned. Typically letter mail prepared to Nonautomation Carrier Route categories (Basic, High Density, and Saturation) will not be processed on automation equipment. However, in some instances, machinable letters destined for AZI 3 zones (i.e., CSBCS zones) and AZI 4 zones (i.e., DBCS zones) may be processed on automation equipment. Use the AZI table to determine scan expectations.
5-3.4.2	Flats — All Classes
The following rules are most applicable to mail that meets the characteristics for processing on the automated flat sorting machine 100 (AFSM 100). Mail that exceeds AFSM 100 processing characteristics may be processed on a flat sorting machine 1000 (FSM 1000) in manual mode. The probability of receiving scans is higher in the area distribution center (ADC) and Mixed ADC categories and diminishes at the 3-digit presort level, and 5-digit mail that exceeds AFSM 100 characteristics is very unlikely to be processed on automation equipment.
a.	Automation Mixed ADC and Automation ADC. Typically, flat mail in these categories will be processed on automation equipment.
b.	Automation 3-Digit. Typically, flat mail in this category will be processed on automation equipment, with the exception of mail that is drop-shipped by a mailer or directly routed from origin to an SCF that does not have flat sorters.
c.	Nonautomation Single-Piece. Typically, flat mail in these categories will be processed on automation equipment, with the exception of mail that originates and destinates in SCFs that do not have flat sorters.
d.	Automation 5-Digit. Flat mail in this category may be processed on automation equipment. Use the nonautomated 5-digit ZIP Code table to apply exceptions.
e.	Enhanced Carrier Route (ECR) categories (Basic, High Density, and Saturation). Mail in these categories will not be processed on automation equipment.
f.	Presorted Basic. Typically, flat mail in this category will be processed on automation equipment. (This rate category is comprised of Mixed ADC and ADC, so it should be scanned.)
g.	Presorted 3/5. Flat mail in this category may be processed on automation equipment. Use the nonautomated SCF table and nonautomated 5-digit ZIP Code table to apply exceptions.
Note: Mixed ADC and nonautomation single-piece are only originating operations.
Note: Origin entry or destination entry at the destination national distribution center (DNDC), destination area distribution center (DADC), or destination sectional center facility (DSCF) level should not impact scan expectations since the flat or letter will be processed based solely on the presort level, independent of entry. The only potential exception would be the destination delivery unit (DDU) entry of machinable enhanced carrier route letters, which may reduce the scan expectation when compared to “upstream” entry since the pieces must be backhauled to the plant for processing if a scan is to be recorded, and the delivery unit has the option to case these letters or take the letters straight to the street on mounted routes. The Postal Service’s policy is to backhaul these pieces to the processing facility in order to reduce costs, as long as this does not sacrifice service.
