Effective April 1, 2025, the Postal Service™ will revise Labeling List(s) L003, L011, L012, L015, L051, and L801 to reflect changes in mail processing operations. Mailers are expected to label according to these revised lists for mailings inducted on or after the April 1, 2025, effective date through the May 31, 2025, expiration date.
Note: Due to the extensive number of changes to the following Labeling Lists, the changes will not be published in this Postal Bulletin. Additionally, as of April 1, 2025, these Labeling Lists will be deleted from the External Label Lists:
n L003 3-Digit ZIP Code Prefix Groups — 3-Digit Scheme Sortation
n L011 Non-NDC/ASF Entry — Periodicals and Standard Mail Letters
