CIPZIP Act of 2025

Section 2(b)(1) requires the Postal Service to establish and make public a clear administrative process for State, local, and Tribal governments to request ZIP code modifications. This gives communities a formal way to address their mailing area needs.

Section 2(b)(2)(B)(ii) ensures that if a government's request is denied, the Postal Service must provide a written rationale explaining the decision, including whether financial costs were a factor and the estimated cost. This holds officials accountable and gives the public clear answers.

Section 2(b)(2)(D)(iii) allows any State, local, or Tribal government that was denied a ZIP code modification during the ten years before the enactment of the Act to resubmit their request. This gives past denied communities a fresh opportunity for review.

Section 3(b)(2) states that if cost is the only reason a request is denied and the government is able to pay or defray that cost through a pilot program agreement, the Postal Service must accept the agreement and grant the request. This provides a clear path to getting a ZIP code changed if funding is provided.

Section 2(b)(2)(D)(i) prohibits a State, local, or Tribal government from submitting an identical or substantially similar request to modify a ZIP code for a period of five years after a denial. This creates a long waiting period for communities that are turned down.

Section 2(b)(2)(E)(iii) limits governments to submitting only one appeal per request if their ZIP code modification is denied. This restricts their options to challenge an unfavorable decision.
