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 Mississippi is in the Central time zone, which keeps scheduling logic simple.
• A quick sanity check: a valid MS 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.
