PO Box Fees for Merged Locations

Yesterday the Federal Register published our final rule, allowing Post Office Box™ (PO Box™) fee groups to be merged due to Post Office™ mergers and allowing fee groups to be changed more than one level higher or lower at a time, in limited circumstances.

This change is effective November 7, 2011.

The complete final rule Federal Register can be found on the Federal Register website at and is available on the Postal Explorer® website at
