Because the Census Bureau no longer tabulates decennial data by U.S. Postal Service ZIP Codes, there will be no updated versions of this file. Try contacting the U.S. Postal Service.
Since this is not a formal product, we do not accept corrections or updates from the public. The only corrections that we can accept to the ZIP Code information in our internal data base is through our various cooperative programs with the U.S. Postal Service.
