Publication 205, Electronic Verification System Technical Guide

The Postal ServiceTM has issued Publication 205, Electronic Verification System Technical Guide, with an effective date of October 2006. Available electronically on the Postal Service Web sites, Publication 205 contains the business requirements and the technical specifications to be used by parcel mailers, shippers, and software developers planning to manifest parcel mail under the Electronic Verification System (eVS). Future revisions to Publication 205 will be announced and published in the Postal Bulletin.

Beginning August 1, 2007, eVS will be required for all permit imprint Parcel Select mailings and for permit imprint commingled parcel mailings authorized under Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM) 705.6.0 or 705.7.0. A final rule on this requirement, along with a detailed analysis of comments received from the mailing public, was published in the Federal Register on July 10, 2006 (see 71 FR 38966-38978).


Publication 205 is organized into seven chapters and a series of seven appendices that guide mailers through the necessary steps and technical requirements for the eVS program.

Chapter 1, "The Basics," explains the benefits of the eVS program and its required and optional use, outlines what is needed in order to participate in the program, and details postage computation and the use of the special eVS permit imprint indicia.

Chapter 2, "Electronic Files and Manifests," presents the eVS file and manifest structure, including format and layout, and discusses file transmission.

Chapter 3, "Barcode Requirements," introduces the technical specifications for the UCC/EAN Code 128 barcodes required for eVS, including barcode symbology and related elements, barcode identification format and human-readable information, printing specifications, and the calculation of the barcode check digit.

The Postal Service collects any postage due for the underpayment of postage, for unmanifested parcels, and for misshipped parcels.

Specific areas include documentation, customer identification process, barcode read rate, accountable mail parcels, internal sampling, file management, and other quality measurements for improvement and transportation scheduling.

Chapter 6, "eVS Reports," details the various online reports that allow the eVS mailer to monitor the accuracy of mailings and postage payments and to take corrective action, if necessary, to minimize the potential for postage adjustments.
