Validate an Address

HTTP Request

POST /v1/addresses/verify


Address validation verifies and cleanses postal addresses within the United States to help ensure packages are rated accurately and shipments arrive at their final destinations on time. The Validate Address operation sends an address to be verified. The response indicates whether the address is valid and whether the validation check made changes to the address.

Things to Consider

  1. Only U.S. domestic addresses are validated using this POST operation at this time.

  2. Addresses are validated by the Pitney Bowes Address Validation (AV) engine.

  3. By default, address validation does the following:

    • Verifies the delivery line (street address) and last line (city/state/postal code) for completeness.
    • Returns an error if the address is incomplete or if current USPS data indicates no delivery to that address.
    • Makes corrections to the delivery line or last line when possible.

    If you set the minimalAddressValidation query parameter to true, the API changes the behavior of bullet 3: the API makes corrections only to the last line (city/state/postal code). The delivery line (street address) is returned exactly as specified in the request. Keep in mind, the API still checks the whole address for completeness and still returns an error if any part of the address, including the delivery line, is incomplete or marked “Undeliverable” by USPS. If you use minimal address validation, always ensure the delivery line you enter is actually deliverable.

  4. Address validation returns 2-digit delivery points when available. You can find more information on delivery points at the Wikipedia Delivery Point page. If you use minimal address validation and if the delivery line (street address) cannot be confirmed, the response will not include the delivery point.

  5. If validation fails, you can use the Suggest Addresses API call to provide suggestions that could result in the address passing verification in a subsequent Address Validation API call.
