Fraud Management Filters Summary
Advanced Fraud Management Filters
42 June 23, 2009 Fraud Management Filters
maximum amount trigger this filter. An unusually high total amount can indicate potential
fraudulent activity because fraudsters generally aren’t price sensitive as they aren't paying
with their own money. The Maximum Transaction Amount filter applies to all payments.
Unconfirmed Address Filter
This filter screens for payments above the specified amount when the shipping address entered
by your customer has not yet been confirmed by PayPal as belonging to the PayPal account
holder. A confirmed address is less likely to be used for fraudulent activity; however, there are
many valid reasons why a customer's legitimate address may not be confirmed. For example,
the customer may have recently moved or may live in a country where address confirmation is
not available. Currently, only addresses in Canada, the United Kingdom, and the United States
can be confirmed. You can also specify a maximum amount for the payment, in which
amounts lower than the specified amount are not checked. The Unconfirmed Address filter
applies to all payments.
NOTE: All payments made using debit cards, credit cards, and Virtual Terminal are
considered to be from unconfirmed addresses.
Country Monitor Filter
This filter screens for payments from countries that you believe to pose an increased risk of
fraud by screening a customer’s IP address, billing address, and shipping addresses for
matches with the countries you specify. Orders from customers in some countries can have a
relatively higher incidence of fraud, especially where it is difficult to authenticate information
about residents of the country. The Country Monitor filter applies to all payments.
Advanced Fraud Management Filters
Advanced Fraud Management Filters, which are optional, provide additional protection aimed
at detecting fraud in credit card payments.
Advanced Fraud Management Filters are only available with Website Payments Pro. You can
upgrade to these filters on PayPal. If you no longer want advanced fraud management filters,
you can downgrade by contacting PayPal customer support.
Card and Address Validation Filters
You can filter transactions based on address information or credit card security code.
Address Verification Service No Match Filter
This filter screens for payments for which the billing address entered by your customer doesn’t
match the information maintained by the card issuer, as determined by the Address
Verification Service (AVS). This filter corresponds to AVS response codes N or C. AVS
