Standard Summary
Comprehensive overview in 1-2 paragraphs

This bill would require the United States Postal Service (USPS) to designate a single, unique ZIP Code for certain communities within 270 days after the bill becomes law. In the text provided, the two communities named are Mills, Wyoming, and Star Valley Ranch, Wyoming. The bill’s sponsors are Senators Barrasso and Lummis, and it was introduced in the Senate (S. 2364) and referred to the Committee on Homeland Security and Governmental Affairs. The core idea is to give each of these communities its own distinct ZIP Code rather than sharing a ZIP that might cover surrounding areas. The stated purpose is to assign single, unique ZIP Codes to these communities, which could affect mail routing, address databases, and community identity. The full scope beyond the two listed communities is not included in the excerpt provided, so the precise range of “certain communities” beyond Mills and Star Valley Ranch is not known here.
