Labeling List Changes (December 2021)
Effective January 1, 2022, we are revising Labeling List(s) L009, L011, L012, L014, L015, L051, L201, L601, and L605 to reflect changes in mail processing operations. Mailers are expected to label according to these revised lists for mailings that are inducted on or after the January 1, 2022, effective date, but no later than February 28, 2022, expiration date. The changes will be published in the Postal Bulletin, Issue #22587.
