This legislative proposal mandates the United States Postal Service (USPS) to establish a single, unique ZIP Code exclusively for Highland City, Utah. The bill specifies that this new ZIP Code must encompass only the geographical area of Highland City, ensuring its distinct postal identification. The USPS is required to implement this designation within 270 days following the enactment of the Act. This measure aims to provide Highland City with its own distinct postal identifier, potentially improving mail delivery accuracy and community recognition by separating it from surrounding areas.
