what is billing address debit card refers to the registered address associated with a debit card, used primarily for verifying transactions and preventing fraud. When making online purchases, users must input their billing address exactly as it appears with their bank or card issuer to ensure successful authorization. This address is linked to the account where the cardholder receives statements and is not necessarily the same as a shipping address. If the billing address doesn’t match bank records, the payment may be declined. Understanding the difference between billing and shipping addresses is crucial when ordering online, especially for international buyers. For businesses, capturing accurate billing information helps reduce chargebacks and fraudulent transactions. Billing addresses also play a key role in AVS (Address Verification Systems), a security tool used by many online retailers and payment gateways.
