Address Validation

Address Validation is the verification of address information. The service uses a database supplied by the United States Postal Service (USPS) to determine if an address is a deliverable address. The service will also return the address in the standardized USPS format. The service can be accessed either by providing a file which will be run as a batch process or by submitting addresses one at a time to our web service. In addition to the return of the address itself, we can also provide additional information such as county number, county name, geo code and congressional district. An additional item that is offered is the National Change of Address. If you provide 100 or more unique addresses, we can process the files through the National Change of Address (NCOA) data to determine if the person, family or business has moved. If the move is within the last 18 months, we can return the new address. We can also provide information detailing if the move is for an individual, a family or a business. There are many advantages to address verification:

  • Addresses in a database can be searched more effectively as they are in the same format. The spellings of streets and cities are the same throughout the database.
  • Postal discounts can be obtained when the addresses are standardized and processed through the NCOA. Agencies can see a decrease of as much as 10 cents per item mailed.
