The database does not contain every city or zip code that has ever existed in the U.S. It only contains the Preferred City Name and zip code as designated by the USPS.
Zip codes are constantly being added or deleted. Some months may only contain a few changes while others may have hundreds of zip codes and cities added or deleted.
We strive to keep our data as accurate as possible but with the number of changes that take place it's possible errors can occur.
