Utah ZIP Codes: Ranges, Prefixes and Major Cities

Whether you are building an address form, cleaning a mailing list or testing shipping rules, it helps to know how ZIP codes work in Utah. The state has 345 active codes spread across 29 counties.

ZIP code range and prefixes

Every Utah ZIP code starts with one of 8 three-digit prefixes. Each prefix points to a sectional center facility, the processing plant that sorts mail for a group of nearby post offices.

Salt Lake City is the state capital. Larger cities have many ZIP codes because each code follows mail delivery routes, not city limits.

Sample addresses

Carlos Allen 7194 Elm Way Alpine, UT 84004
Elizabeth Anderson 5632 Willow Ln Alpine, UT 84004
Linda Rivera 5818 Oak Rd Cedar City, UT 84720

These examples use real city and ZIP pairs with invented street lines, so they are safe for testing and documentation.

Tips for working with these ZIP codes

  • Store ZIP codes as text, not numbers, so the format stays consistent across states with leading zeros.
  • All of Utah is in the Mountain time zone, which keeps scheduling logic simple.
  • A quick sanity check: a valid UT ZIP code begins with one of the prefixes listed above.
  • City names in addresses are post office names. A suburb may share a ZIP code and city name with a nearby larger town.

Create realistic Utah addresses for testing, with real cities, counties and ZIP codes.
