If you receive a zip code scrubbing error, it is because one of the addresses on the claim form does not match with the USPS database.
Confirm zip codes include the 4-digit extension
The most common reason for this error is using zip codes without the 4-digit extension. This is because most payers require 9-digit zip codes on electronic claims. Use this site to get the 9-digit zip code: USPS Zip Code Look Up tool.
You sometimes need to remove the street address to find the correct 9-digit zip code on the USPS site. For example, if you are searching 2003 Curson Ave, try searching just Curson Ave with the city and state.
