Fraud Filter Reference
International Order Filters
A
NOTE: Unlike the Risk lists managed by PayPal, you, solely, manage and update the Bad
Lists.
Any transaction that is an exact match with an entry in one of your bad lists triggers the filter.
If you enable this filter, then your next step will be to set up lists of bad email addresses and
bad card numbers. Be sure to type the e-mail addresses and credit card numbers accurately.
Enter only numerals in the credit card number list—no spaces or dashes.
NOTE: Items that you enter in the test Bad 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.

domestic customers. This is due to the difficulty of authenticating foreign citizens and the
difficulty of cross-border legal enforcement against fraudulent activities.
Certain countries, however, are much riskier than others. These countries have high likelihood
of fraud and you should evaluate transactions from these countries closely.
International Shipping/Billing Address Filter
What does the filter do?
This filter screens the customer’s shipping and billing information for non-U.S. addresses. The
filter checks for country code 840, or any derivation of “United States” (U.S., USA, United
