With the Address Validation Street Level Application Programming Interface (API) capabilities as part of your integrated enterprise applications or website, you can be sure your customer's shipment is going to a valid address. Using the United States Postal Service® (USPS) database of valid addresses in the United States and Puerto Rico, the Address Validation Street Level API validates the address of your customer's shipments.
While validating addresses with the Address Validation Street Level API, if an error is discovered, the API can provide a list of potential valid addresses. Additionally, this API uses address classification to determine if an address is residential or commercial.
This API requires XML/Web Services programmers to code and integrate. UPS provides a developer guide that explains how to integrate and code UPS functionality into your existing business applications or e-commerce website.
