PAV (Postal Address Verification) is a CASS Certified™ API that allows you to standardize, correct, and validate U.S. and Canadian addresses in one step. Save time, money, and resources by verifying that addresses are deliverable before mailings or packages are sent out.
Create a client in any programming language to interact with the API. See our Quick Start Guides to get started with some of the most common platforms. If you have questions, look at our FAQ or contact us.
