The Postal Service is making changes to its Domestic Mail Manual (DMM) by eliminating three current labeling lists—L003, L011, and L801—and directing those services to existing lists L002, L005, or L009. This marks the first step toward a new shape-based labeling system aimed at improving mail processing efficiency. The changes, part of a broader 10-year plan, are set to take effect on January 19, 2025, with a grace period for mailers to adjust until April 1, 2025. The goal is to streamline operations and reduce errors by aligning mail preparation and entry with newly established USPS processing points.
Simple Explanation
The Postal Service is changing some of its mail-sorting rules by getting rid of three old lists and using a few others instead; they hope this will make things work better and faster. They'll start doing this in 2025, but they'll give people until April 1st to get used to the new way.
