What is a billing address? … A billing address is an address connected to a specific form of payment, which is typically a credit or debit card. Companies use the billing address to verify the authorized use of such a card. It is also where companies send paper bills and bank statements.
The billing address is used to confirm that the credit card is not being used by someone it shouldn’t. Amazon will not send any bills or receipts to that address. It’s an additional layer of security meant to ensure that credit cards are used by their owners.
A bill is only sent to the billing address if an account requires payment from Amazon’s collections department.
