Labeling List Changes effective August 1, 2015

The United States Postal Service® (USPS®) announced changes to the Labeling List data, effective August 1, 2015, with an expiration date of September 30, 2015. The Labeling Lists affected are L006, L007, L012, and L606. The Labeling Lists are located on the Postal Explorer web site under the Additional Links tab. This will direct you to the Facility Access and Shipment Tracking System (FAST) web site; from there you can choose Resources, then Label Lists File Download, then Label List Files.

Use of Labeling List Data
The Labeling List data is used to define the specific destination information to be printed on sack labels, tray labels, and pallet labels. This destination information is used to route the mail inside the sacks, trays and pallets to the correct postal facility for processing. The destination information is based primarily on 3-digit ZIP Code prefix, and varies based on the class of mail, processing category, and other criteria. Virtually all container labels are generated using computer software, which accesses this Labeling List data in a file format, operating much like a look-up table.

Why the changes?
There are many reasons why the USPS makes changes to the Labeling List data. Recently, many of the changes are being made as a result of their efforts to consolidate processing facilities to improve efficiencies and reduce costs. Changes also take place when the USPS makes alterations to the service areas for certain processing facilities, which can be the result of shifts in population, mail volumes, staffing and many other reasons. Keep in mind that approximately 12% of the US population moves each year and there are about 1,800 new delivery addresses added each day. So, there are lots of ZIP Code changes happening all the time!

Time for change
The USPS modified the frequency of these updates last fall from quarterly to monthly. What this means for mailers is that Labeling Lists are now effective for a period of only two months. While these updates have always been important to insure proper direction of the mail, keeping up to date is now more critical than ever. Gone are the days when mailers could perform their postal presort process months in advance. Due to this change, the maximum advance time for the presort process is 60 days, and in reality probably less than that to accommodate production schedule fluctuations. The scheduled and actual induction dates (mailing dates) also become much more critical as a result of this change. These dates are what is used by the USPS to determine if valid Labeling Lists have been used to process the mailing.

Handling Change
When these types of changes are announced, it is important for mailers to work with their software vendors and mail service providers to make sure that the changes are implemented on a timely basis. This is critical so that the correct destination information is populated into the Mail.dat® files, or any other files or printed documents that are used to process or submit postage statements (and other postal documentation) and to create sack, tray, and pallet labels. Keep in mind that the Labeling List changes involve not just the facility names, but the ZIP codes associated with those facilities. This affects the destination line on the tags and the mailpieces that are placed into the sacks, trays, and pallets. As such, these changes MUST be incorporated into the presort software first; if the data is incorrect during this process (and thus incorrect in the Mail.dat files), it cannot be corrected in Post-Presort software, such as DAT-MAIL™.
