Cleared committee, waiting for its first floor vote
A committee approved it and it is on the calendar of the chamber it started in.
This is further than most bills get, and still no promise of a vote: the calendar is a queue, and the majority leadership decides what is called. A bill can sit here until the Congress ends.

What this bill would do
This bill is known as the Community Involvement and Partnership in Zone Improvement Plans Act of 2025 or the CIPZIP Act of 2025. It requires the United States Postal Service to create an administrative process for State, local, and Tribal governments to request ZIP code modifications. The bill establishes a pilot program allowing these governments to enter into agreements with the Postal Service to help cover the costs of ZIP code boundary changes or realignments. It sets rules for how the Postal Service must handle denials, written explanations, and cost estimates for these requests. The legislation also creates reporting requirements for the Postal Regulatory Commission and individual members of Congress regarding these requests. Finally, the pilot program includes a sunset provision ending it seven years after enactment.

Who it would affect, and how
Potential Positive Impacts for People
-
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.
Potential Negative Impacts for People
-
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.
