Tips for working with these ZIP codes
- Store ZIP codes as text, not numbers, so the format stays consistent across states with leading zeros.
- Alaska spans more than one time zone (Alaska, Hawaii-Aleutian and Napakiak). Use the ZIP code or county, not the state, to decide local time.
- A quick sanity check: a valid AK 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 Alaska addresses for testing, with real cities, counties and ZIP codes.
