Latest action (3 Sep 2026): Referred to the House Committee on Oversight and Government Reform.
What this bill does
H.R. 10257 would direct the United States Postal Service to designate a single, unique ZIP Code for each of a specific list of communities named in the bill—80 in total, spanning states including California, Colorado, Connecticut, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, Minnesota, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, South Carolina, Texas, Utah, Virginia, Wisconsin, and Wyoming. The Postal Service would have one year from the bill's enactment to complete these designations.
The bill affects residents, businesses, and local governments in these named communities, many of which reportedly currently share ZIP Codes with neighboring towns or cities rather than having their own distinct designation. A unique ZIP Code can affect how a community's address appears, which may have implications for local identity, mail delivery, and how the area is recognized in databases tied to ZIP Codes (such as for shipping, marketing, or municipal statistics), though the bill itself only addresses the ZIP Code designation and does not detail these downstream effects.
The bill was introduced on September 3, 2026, by Rep. Mario Diaz-Balart along with several cosponsors from both parties, and it has been referred to the House Committee on Oversight and Government Reform. As an introduced bill, it would need to be considered and approved by that committee, then passed by the full House and Senate, and signed by the President before becoming law. No further legislative action has yet occurred.
