To direct the United States Postal Service to designate single, unique ZIP Codes for certain communities, and for other purposes.

The bill would direct the United States Postal Service to designate a distinct, exclusive ZIP Code for each of 66 specifically named communities in California, Colorado, Florida, Illinois, Indiana, Kentucky, Louisiana, Minnesota, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, South Carolina, Texas, Virginia, and Wisconsin. The USPS would be required to complete these designations within 270 days of the bill's enactment. The communities listed currently lack a single unique ZIP Code of their own, meaning their addresses overlap with broader or neighboring postal zones.

The bill does not appropriate funds, prescribe how USPS must administer the new ZIP Codes once assigned, or address what happens if the agency misses the 270-day deadline. It applies only to the communities named in the text; no general authority is created for other communities to petition for unique ZIP Codes under this measure.

Residents, businesses, local governments, and emergency-services providers in each of the 66 listed communities, who currently share ZIP Codes with neighboring areas. The U.S. Postal Service would be directly directed to act. Mail carriers, package delivery services, and anyone who uses a listed community's address in databases, maps, or official records would also be affected.

Shared ZIP Codes can cause misrouted mail, confusion in emergency-dispatch systems, inaccurate demographic and commercial data tied to postal geography, and a loss of community identity in official records. A unique ZIP Code would give each listed community a cleaner address boundary, which matters especially for growing suburban and exurban municipalities that have incorporated or expanded but still carry inherited postal zones.

The bill imposes a single, self-executing deadline: USPS must complete all 66 designations within 270 days of enactment. The bill specifies no rulemaking process, no community petition mechanism, and no reporting requirement. USPS would need to internally assign new five-digit codes, update its postal database, notify affected post offices and delivery routes, and coordinate with local governments and address-database vendors. The bill provides no appropriation to cover those administrative costs and sets no fallback if the deadline is not met.
