The Credit Card Generator is a free online tool that generates valid-format credit card numbers for software development and testing purposes. These numbers pass the Luhn algorithm checksum used by payment systems to verify card number structure — but they are not real cards and cannot be used to make actual purchases or transactions.

Developers building e-commerce sites, payment forms, shopping cart systems and fintech applications need test card numbers that follow the correct format rules for Visa, Mastercard, American Express, Discover and other card networks.

How to Use the Generator

• Select the card type (Visa, Mastercard, Amex, Discover, etc.)
• Choose quantity (1–10 cards)
• Click Generate
• Copy the card numbers along with expiry dates and CVV for testing

Supported Card Networks

• Visa (starts with 4)
• Mastercard (starts with 51–55)
• American Express (starts with 34 or 37)
• Discover (starts with 6011)
• JCB and Diners Club

Important Disclaimer

Generated card numbers are for testing only. Using them in any fraudulent manner is illegal. For payment gateway testing, use the official test card numbers provided by Stripe, PayPal or your payment processor. Free, no login required.
