This legislation mandates that the United States Postal Service (USPS) designate single, unique ZIP Codes for certain communities. The bill specifies that this action must be completed within 270 days following the date of its enactment. Specifically, the USPS is directed to assign distinct ZIP Codes to Mills, Wyoming , and Star Valley Ranch, Wyoming . This measure aims to provide these particular localities with their own unique postal identifiers, potentially improving mail service and community recognition.
