This filter compares the customer’s email address and credit card number against lists (that you create) of addresses and numbers for known good customers. You create the lists.
Unlike the High Risk lists that PayPal owns and manages, you, solely, manage and update the Good Lists.
Any transaction for which the email address or credit card number is an exact match with an entry in one of your good lists is automatically accepted and no other filters are applied. Enter only numerals in the credit card number list—no spaces or dashes.
If you activate this filter, then your next step will be to set up lists of good email addresses and good card numbers. Be sure to type the email addresses and credit card numbers accurately.
Items that you enter in the Test Good lists are not carried over to your configuration for the Live servers, so do not spend time entering a complete list for the Test configuration.
To ensure that loyal repeat customers are not held up by your fraud review process, you may wish to create lists of email addresses and card numbers that should be automatically accepted. This ensures that an abnormal shopping pattern on the part of a loyal customer (for example making a purchase while on vacation overseas) does not trigger a filter and delay the transaction.
Good Lists do not authenticate individuals and therefore will not prevent a fraudster from using a stolen credit card or email address. To prevent use of stolen information, use Good Lists in conjunction with other filters, such as the Buyer Authentication Failure Filter.
