Development and testing often require a large amount of valid credit card data, but using real card numbers poses security risks. This tool uses the Luhn algorithm (modulus 10) to generate virtual credit card numbers that meet international standards, supporting major networks like Visa and MasterCard. Although these 16 to 19-digit sequences pass basic validation, they are strictly dummy data and cannot be used for real transactions.
Can the generated card numbers pass bank verification?
No. These card numbers only pass the Luhn algorithm check and are not linked to any real bank accounts.
What are the length differences between card networks?
It is strictly prohibited to use the generated card numbers for actual transactions. We recommend using them in isolated testing environments to avoid any data leak risks. When generating in bulk, please note the maximum limit is 100 numbers per request.
When testing payment systems, it is recommended to use a Bank Identification Number (BIN) table to verify that the first 6 digits of the generated card match the network's specifications. Typical examples:
Visa cards usually start with 4, MasterCard with 51-55, and UnionPay cards with 62.
