How To: Verify if a ZIP Code is included in Esri's current roster
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.
Go to the following site: USPS Zip Code search page
- On the Quick Tools tab and click Look Up a ZIP Code.
- Under Cities by Zip Code, click Find Cities by ZIP.
- 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.
- 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.
