If your application requires a quick, accurate address, you can use the USPS Address Validation API. This service helps you resolve address problems and ensure that shipments reach their destinations in a timely manner. The API will take the address information you provide and format it to produce a real-world address. It will also provide annotations about deficiencies or changes in the address.
The USPS address validation API works by comparing an address's last line with current data from the USPS. It can also make corrections to the last line of the address. The API supports two address validation levels: complete and minimal. Complete address validation is the default option. Minimal validation allows you to limit the number of corrections.
USPS address validation API is a set of public address lookup APIs that allows developers to access the official address database of the United States Postal Service (USPS). The database contains over 160 million US postal addresses, complete with ZIP code and city details. It helps improve the quality of address data and improve the customer experience.
The USPS address validation API works to correct incorrect addresses by fixing typos, case, and spelling errors. It also helps standardize the address by converting it into the USPS format. To get an address, you need to include the "ST" or "STE" code or a +4 code, which is provided by the USPS.
