Processing addresses is a challenge for all of us, credit card companies included. It was, therefore, no surprise to me to learn how cursory the address check on credit cards for online purchases actually is.
For many countries there is no address check.
For the UK the check is only on building number and the numbers of a postal code, so the check for 10 Downing Street, SW1A 2AA would be 1012. As a very large number of addresses in the UK will share this same code, it's a check that is very easy to get around.
Considering the amount credit card companies lose to fraudsters, and the stress involved for the legitimate credit card holder, isn't it time that these companies put some time and resources into learning about addresses?
