CIPZIP Act of 2025

This section mandates the Postal Service to establish and make public an administrative process within 180 days for State, local, and Tribal governments to request changes to ZIP codes within their jurisdiction. This includes amending existing boundaries or establishing new ones. The process must define criteria for evaluating requests, provide written rationales for denials (including cost estimates if applicable), and designate a public point of contact.

The bill prohibits governments from submitting identical or substantially similar ZIP code modification requests for 5 years after a denial, but allows alternative requests. It also permits any government denied a request in the preceding 10 years to resubmit it. Furthermore, it establishes a formal appeals process for denied requests, requiring appeals within 45 days and limiting them to one per request.

This section re-establishes a pilot program allowing the Postal Service to enter into agreements with State, local, or Tribal governments to receive money, property, or services to cover the net costs of a ZIP code boundary change or realignment. If a request is denied solely due to net cost, the USPS must notify the requestor, provide a cost estimate, allow 30 days to propose a cost-defraying agreement, and accept the agreement if it covers the cost. The program sunsets after 7 years.
