How do I restrict International Payments to PayPal?
Q: How do I restrict my international credit card transactions to use PayPal only?
A: The best way to restrict your payment method for international orders to PayPal is to not offer options for them to pay through your regular merchant account. You can do this by changing your settings with your Payment Gateway. Below are the steps to complete the setting if your payment gateway is Authorize.net
Log into http://authorize.net
Click the Account tab
Click Address Verification Service
Check the checkboxes: B,E,R,G,U,S, and N
View Authoriz.net's Merchant Guide: http://www.authorize.net/support/merchant_guide.pdf, starting on page 22 for details on B,E,R,G,U,S, and N.
We then recommend that you place information on your cart screen to notify your International Customers to select PayPal.
