The Address Verification Service (AVS) checks the billing address a customer types in at checkout against the address the card issuer has on file. It's one of the oldest fraud checks for online and phone card payments.
What it checks
AVS usually compares the numbers in the street address and the postcode or ZIP code, not the full address. It's widely used in the UK, the US and Canada, and less so elsewhere.

What businesses do with it
AVS doesn't approve or decline a payment by itself. The business or its payment provider chooses the rules, such as declining a no-match on a high-value order. Genuine customers can fail AVS after moving house, so strict rules can turn away good sales.
Working with other checks
AVS works best alongside the CVV check and 3D Secure, where the customer confirms the payment with their bank.
