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

Sample addresses

Richard Carter 9297 Jefferson Ct Saint Louis, MO 63147
Elizabeth Young 5963 Franklin Ave Kansas City, MO 64105
Kevin Patel 1798 Park Blvd Ballwin, MO 63021

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 Missouri is in the Central time zone, which keeps scheduling logic simple.
  • A quick sanity check: a valid MO 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 Missouri addresses for testing, with real cities, counties and ZIP codes.
