Why does it say my zip code is invalid?

The SME database cross references the USPS postal code database for address validation. Several reasons why your zip code may have been returned as invalid are:

  • No such rural route number or rural route box
  • Rural route address change to city-type address
  • Incorrect or missing ZIP code
  • Incorrect or missing city and/or state
