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.
