How it works

Our industry-leading address verification solutions help you verify addresses everywhere you collect data. How? We do it by correcting spelling and formatting errors on the fly, prompting users for missing address details, and appending ZIP + 4® information. With our address validation solutions, getting complete and standardized contact data has never been easier. 

What is address verification?

How important is clean address data to you and your organization? If the address information you collect isn't kept accurate and up-to-date, your business can be impacted in ways you may not have considered. Research shows that 83% of companies believe that revenue is affected by inaccurate and incomplete customer or prospect data. With Address Verification from Experian Data Quality, you can be confident that the addresses that you are capturing are accurate and complete the first time they are entered. And because all you need to enter is minimal information, such as a ZIP code, you'll reduce around 80% of the key strokes it would normally take to enter a typical mailing address. Our tools can also help you validate addresses already in your database, so you can be confident that the information you hold is accurate over time. So why does it matter? Most importantly, your customers will have a better experience. Quick and easy verification enhances the customer journey on your website and makes users more likely to submit forms and complete their purchases. You'll also reduce costs and improve efficiency, because less of your precious time is wasted manually correcting errors. Correct addresses also mean less returned mail and a greater ability to make accurate business decisions. Get in touch today to discuss the Experian Data Quality tool that's right for your business.

What our customers say

Now we know if an address is invalid right away, while the caller is still on the phone. Rather than having to go back later and look things up in the phone book, we can simply ask for clarification. It saves an enormous amount of time.
