With UPS Address Validation you don't have to worry about your customers entering incorrect address information. If customers make a mistake, UPS Address Validation alerts them with an error message, ensuring that errors are corrected at the point of entry long before orders leave the shipping dock. This reduces costly returns for you and headaches for your customers. The UPS XML Address Verification Tool PHP Function Library streamlines your integration and development process by taking care of the XML dirtywork and returning the result data in the form of an array.
