Address Validation Service - 2008/04

API Description

Once implemented our USPS address validation API checks addresses at the point of entry, instantly correcting any transposed numbers, misspelled street names, or missing information. A cleansed address not only assures accurate Sales & Use Tax calculations, it ensures deliveries are on time and correct, invoices are sent to their intended recipient and are paid, and your marketing mailings reach their audience.
