Address Verification

Ensure only accurate, deliverable addresses enter your database and keep your system clean and up to date. Our best-in-class address validation solution plugs in to your existing applications and maintains the integrity of your contact information over time, cleansing your customer records against the latest U.S. Postal Service® (USPS) address data.

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.
