A billing address is an address that is registered under your credit card, or the address your credit card statements are sent to.
To ensure that your billing address is correct, please check your credit card statement, or contact your card issuing company or financial institution. Please note that if you are moving and you have changed your billing address recently, it may not be reflected immediately. We may contact you to verify your billing address for security reasons.
It is standard practice for online retailers to require that the correct billing address is entered when making your purchase as a security measure that helps avoid unauthorized use of your card.
