This bill directs the United States Postal Service (USPS) to designate a single, unique ZIP Code exclusively for Highland City, Utah. The new ZIP Code will apply solely to the geographical area of Highland City, ensuring it possesses its own distinct postal identifier. Under this legislation, the USPS is mandated to complete this designation within 270 days after the bill's enactment. This measure aims to provide Highland City with an independent and unique postal code, separating it from other areas that may currently share its ZIP Code.
