Hints to Help Identify Online Fraud: things to watch out for
It’s important to watch for common signs of fraud. Though the circumstances below often apply to honest customers, they can also be indicators of illegal activity.
Pay closer attention to orders that are …
Unusually large
Shipping to an address that isn’t the billing address
Shipping to countries you don’t normally ship to (especially if in high-risk areas)
Shipping multiple identical items
Unable to pass an address verification process
Out of the ordinary in any way

Pay closer attention to customers who:
Use an anonymous/free email address (like hotmail.com)
Supply a non-existent or under-construction website address
Use a disconnected or changed telephone number
Supply a fake-sounding physical address (such as 123 Side Street) or only a post office box number
Want shipping as quickly as possible at any price
Do not pass credit or identity checks
Don’t make immediate full payment
Are first time buyers

Pay closer attention to credit card numbers that:
Generate multiple orders over a short time span, especially if each order ships to a different address
Are one of several card numbers shipping to the same address
