Good to know: Numbers start with the network’s public prefix and end with a correct Luhn check digit, so they pass format validation in your own forms. For software testing only. These are not real cards: they are not linked to any bank account and cannot be used to pay for anything. For real payment-gateway tests, use the official test cards for your provider (see Test Credit Card Numbers).

Words to know
- Luhn check
- A quick math test every real card number passes, like a spelling check for numbers. Passing it only means the number is typed in the right shape, not that the card is real.
- Test / sandbox mode
- A practice version of a payment system. You can “pay” with test cards to try your checkout, but no real money moves.
- Public vs private IP
- Your router gives each device a private IP (like 192.168.1.5) at home. The internet only sees one public IP for your whole house.
