How to Use the FedEx Address Validation API

One method to validate addresses is to use the FedEx address validation API. This service provides street-level validation, but does not offer zip/city/state lookups. However, it does cover 45 countries. The API will return a list of possible matches for each address. It also provides information such as the type of address.

To use the FedEx address validation API, you need to first create a production environment. During setup, you will need to setup FedEx production credentials. In the next step, you should enter an address that you are trying to deliver to. The API will then check whether the zip/postal code entered matches the location. If not, it will return an error message. If the address is valid, the API will return a shipping rate for that address.

Another option is to use the USPS address validation API. This service validates a postal address by comparing it to its database. It will also tell you the ZIP+4 code of the address. You can also use this service to obtain city and state information for a specific ZIP Code. The API allows you to request up to five addresses at one time.

Once you have a production environment, you can begin testing the API with a few steps. First, you need to register with FedEx to use the API. Once you've registered, you will receive an API key, account number, or meter number. You can then use this key to test your code. If you find any errors, you can also use the application's Application file to set values.
