Postal Service Mail.XML™ Technical Specification
The Postal Service Mail.XML™ Technical Specification explains the FAST appointment scheduling, Full Service Data Distribution back to customers, eDoc for Full service and eInduction status management through Mail.XML specification.
FAST - The FAST system utilizes the PostalOne! system as the main communication platform with USPS external customers for Mail.XML communication. Customers using the suite of electronic services provided by the PostalOne! system (i.e. eDocumentation) will be able to leverage their existing information within the PostalOne! system to facilitate their appointment scheduling process for the Full-service.
Data Distribution – As part of the Full service program, the PostalOne! system will make the Full Service ACS COA®, Full Service Nixie ACS Nixie, Start-the-Clock, Container Induction scans and Full-service quality verification reporting back to the customers. This Postal Service Mail.XML Specification, available below, covers the technical implementation of data distribution.
eDocs – In May 2009, the PostalOne! system is implementing some basic eDoc messages. In a later release, PostalOne! plans to implement the remaining eDoc messages for a mailing group, postage statements, qualification and other reports, co-palletization, and piece detail and piece range support.
Please check back for updated versions of The Specification to learn about sending Final eDoc data to the PostalOne! system for a later release.
