hi,
I have purchase a Reseller web hosting plan from cpwebhosting.net and start my own web hosting company.A customer signed up for services.How can i check this customer is legitimate or fraud?

For screen all incoming orders for credit card fraud Check:-

1.Order IP Location Match with Billing Address
2. Email Address Verification

Fraudulent orders are often placed for the highest dollar amount possible. In hosting this might mean that a customer is trying to pre-pay for 6 months or a full year. Stolen credit cards tend to be used to buy a longer period since the thief knows the credit card will be canceled and is hoping that it just takes a while so that he can use the hosting account for more criminal activity.

check the information such as customer name and address appear to be formatted correctly? Criminals placing a fraudulent order often don’t take the time to use proper writing/spelling. They just use lower case writing for the entire name and address information. Or they might just use all caps. Watch for both as they are good indicators if the order is placed from a real customer or not. Anyone taking a little pride in himself uses proper upper case / lower case writing for his personal name and address.
