We posted an updated Guide to Intelligent Mail Letters and Flats on ribbs.usps.gov to help mailers prepare for the May 2009 implementation of the basic and full-service Intelligent Mail options. The Guide provides technical solutions for the standards published in the August 21 Federal Register [HTML] | [PDF] and covers electronic documentation, mail preparation, Service Type Identifiers, and data provided for full-service mailings.
The online Labeling Lists available on Postal Explorer at pe.usps.com contain some duplicate entries and do not reflect the changes identified in the following two Postal Bulletins.
L005, L006, L007, L009, L010, L011, L601, L603, and L606
L001, L007, L201, and L606
Mailers that subscribe to the Labeling List feeds through the NCSC or through their software vendors are not affected.
Mailers who use the online lists should contact their local business mail entry unit for clarification before depositing their mail. A complete revised Labeling List will be incorporated into the September 11, DMM monthly update.
