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

HR 8753 requires the U.S. Postal Service to assign a single, unique ZIP Code to 31 specific communities across 10 states, including Eastvale, CA, and The Villages, FL, within 270 days of the bill's enactment. This change directly affects residents and businesses in these communities by standardizing mail delivery addresses. The key mechanism mandates the USPS to establish one distinct ZIP Code per listed community, replacing any existing multi-part or shared codes. This is a procedural adjustment to improve mail sorting efficiency, not a substantive policy change.
