e-VS (Electronic Verification System)  
Document and pay postage using electronic manifest files.
The e-VS, or Electronic Verification System, allows high-volume package mailers and package consolidators to document and pay postage, including special service fees, using electronic manifest files. The files are transmitted over the Internet to a Postal Service™ database. e-VS is designed to make it easy for high-volume package mailers to take advantage of destination entry rates.

e-VS mirrors our existing manual manifest process but does so electronically. Sampling data that is used to monitor postage accuracy is captured after the mailing arrives at the destination entry Post Office™. Instead of reconciling sampling data against individual manifests, it is reconciled against all manifests received from the mailer during the month.

Mailer Benefits
Unlike typical destination entry rate mailings, e-VS mailings are not subject to verification at the origin Post Office or detached mail unit. Mailers have control of their mailings from time of preparation to time of deposit at the entry Post Office, although mailings must still be deposited to meet appointment windows. The mailer no longer has to plan mailings according to the hours of operation at the origin Post Office.

e-VS eliminates paperwork because hardcopy manifests, postage statements and adjustment worksheets are replaced by electronic documentation. Postage is electronically deducted from the mailer’s PostalOne! postage payment (formerly CAPS) account. e-VS mailers can review the results of postage samplings online. Mailers can monitor the quality of their mail, take preventive measures to ensure discrepancies do not recur, and avoid possible postage adjustments.

What may be manifested using e-VS?
e-VS may be used to pay postage and special service fees on domestic Package Service and USPS Marketing Mail™ machinable parcel mailings. Irregular USPS Marketing Mail parcels may only be included in destination delivery unit mailings. Letter-and flat-size mailpieces cannot be included in e-VS mailings.

Inclusion of USPS Marketing Mail and Bound Printed Matter parcels requires computation of an individual price for each parcel. The individual price is calculated by determining the piece rate, pound rate and IMpb non-compliance fee (if applicable) components for each parcel and adding those components together.

Volume Requirements
e-VS is designed for high-volume repetitive destination entry mailers. e-VS mailers must consistently present sufficient volume to destination entry locations to ensure a valid sampling plan can be developed and maintained. The Postal Service will assist a mailer to determine if they have sufficient volume to participate in the e-VS program, based on information provided on the customer’s application.
