When making an online purchase, you will be asked for both a billing address and a shipping address. The billing address is the address associated with the customers payment method, such as a credit or debit card, and is used to verify that the customer is an authorized user of the card. It is also where the bill for the product or service is sent so that it can be paid by the recipient. The billing address can be different from the shipping address, which is the address where the order will be delivered. In some cases, merchants require the same shipping and billing address for online orders, especially for high-value items that may be tempting targets for credit card fraud. It is important to enter the correct billing address to avoid payment rejection and to reduce the possibility of fraudulent activities.
