CIPZIP Act of 2025

This bill establishes a 7-year pilot program allowing local, state, or Tribal governments to cover the Postal Service's costs for ZIP Code boundary changes or realignments, preventing denials based solely on cost. If the Postal Service denies a request due to cost, it must notify the requester, provide a cost estimate, and give 30 days to propose a cost-sharing agreement - accepting the agreement if it covers the cost. The program requires annual reports to Congress on requests, denials, and agreements, plus reports to individual members of Congress upon request. The bill directly affects local governments and Tribal entities seeking ZIP Code adjustments, with the Postal Service required to reconsider cost-based denials through this mechanism.
