Our free address lookup tool provides instant validation that helps you to improve the quality of the address information in your database. All our address verification tools verify information using both domestic USPS® and international address data as well as geolocation data.

Real-time address verification: Our free address lookup tool gives you a taste of our real-time address verification tool. As a customer or user is typing in an address, that data gets verified instantly so that no inaccurate data enters your database.
