The purpose of this legislation is to require the United States Postal Service (USPS) to assign unique ZIP Codes to specific communities across the country. This aims to improve mail delivery efficiency and ensure that residents of these areas have a distinct postal identity. The key provision of the legislation mandates that within one year of the law being enacted, the USPS must designate a single, unique ZIP Code for each of the listed communities. The bill includes a comprehensive list of 83 communities from various states, including California, Colorado, Florida, and others.
