S. 3175 — CIPZIP Act of 2025

This section establishes a 7-year pilot program authorizing the Postal Service to enter agreements with state, local, or Tribal governments to defray net costs of ZIP code boundary changes or realignments. It requires the Postal Service to notify requestors of the program, provide cost estimates, allow at least 30 days to propose an agreement, and grant the request if cost is the sole denial factor and the requestor covers it. The Postal Regulatory Commission must submit annual reports on requests, grants, denials, and agreements to the Senate Homeland Security and Governmental Affairs Committee and the House Oversight and Government Reform Committee, and the Postal Service must provide denial factor reports to Members of Congress upon request.
