The following steps outline how to setup the Risk Controls feature to determine if a payment will be accepted, based on an AVS (Address Verification System) match.

• Logon to your PayPal account.
• Click the Profile tab, and then the Risk Controls link.
• In the Risk Controls – All Payments section, click the Maximum Amount radio button and then Edit.
• In the Risk Control: Maximum Amount section, choose Maximum Amount and Options.
• Enter a Maximum Amount of $0.01 and apply it to the section labeled Payments from unconfirmed addresses only. This option gives you AVS protection—PayPal’s address confirmation includes AVS checks to thwart fraud.
• For the Action to take setting, choose Decline (Decline payments that exceed my Maximum Amount).

With these settings, when customers try to use a credit card that doesn’t have an AVS match, they’ll see a warning and will be prompted to correct the issue.
