What is address validation?

Better customer relations and data you can trust

Customer address data enters your organisation every day through touchpoints like your website, telephone calls, live chats or post.

Experian's powerful intuitive address validation tool uses data from over 240 countries to deliver accurate, fast results. We can even cleanse addresses at point-of-entry and enrich your data with corresponding geocoordinates in real-time, so you can be sure that only accurate billing, shipping and contact addresses with precise geolocation details enter your database.

Watch the video or read our technical information to see how address validation helps you to drive value from your business's most important asset - your data.
