The Puerto Rico Postal Equity Act of 2025 aims to significantly improve the accuracy and recognition of addresses in Puerto Rico by the United States Postal Service. Congress found that historical inconsistencies between local addressing conventions and USPS systems, including the omission or alteration of diacritical marks , lead to recurring delivery failures and data mismatches. This legislation mandates the Postmaster General to develop and implement system improvements within 180 days to address these issues, ensuring proper mail delivery and data integrity for the island. Specifically, the Postmaster General must identify locations with persistent address recognition problems using operational data and update address records, routing information, and validation tables accordingly. The bill requires revising USPS systems to support the use of diacritical marks and other Puerto Rico-specific address elements. Furthermore, the Postmaster General must consult with the Bureau of the Census and local Puerto Rico governments, and report annually to Congress for three years on progress and any barriers encountered, all while utilizing existing USPS funds without additional appropriations.
