How address verification works

Cleanse, correct, and standardize your address records in real time. Our address verification API verifies address at the point of collection so that no inaccurate data enters your database.

Our address verification API integrates easily into your technical environment. You can customize how you want your addresses verified, with no disruption to your existing workflow. That means no interruption in how your customers experience their checkouts or account sign-ups, while still having verified addresses flow into your database.

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.
