Summary

For ZIP Codes that appear to be missing from the current list of available Esri ZIP Codes, the following procedure provides a way to determine if a ZIP Code should be available. These steps show some examples of ZIP codes that would not be included in the list.

Procedure

Go to the following site: USPS Zip Code search page

  1. On the Quick Tools tab and click Look Up a ZIP Code.
  2. Under Cities by Zip Code, click Find Cities by ZIP.
  3. Enter in the ZIP Code(s) in question (for example, '93380') and click Find.

    In the image above, this ZIP Code is for a P.O. Box and therefore is not included in Esri's current ZIP Code roster.
  4. As another example, click Look up another ZIP Code, this time enter ZIP Code '93381' and choose Find. This ZIP Code is also not a valid ZIP Code and therefore is not included in Esri's current ZIP Code roster.
