About the Credit Card Generator
What is a credit card generator?
A credit card generator builds card numbers that look real and pass the same first-line validation a payment form runs, without being tied to any actual account. Ours creates the full set a checkout expects — the primary account number, a matching CVV, an expiry date and a cardholder name — for Visa, Mastercard, American Express, Discover, JCB, Diners Club, UnionPay, Maestro and RuPay. Every number is built to satisfy the Luhn algorithm, the checksum that browsers, gateways and libraries use to reject typos before a card is ever sent for authorization.
The important part, and we cannot say it enough: none of these are spendable. There is no bank, no balance and no cardholder behind them. They are the payments equivalent of Lorem Ipsum — realistic filler you can drop into a form to see how it behaves. We built this because wiring up a checkout, a subscription page or a fraud rule and testing it by hand with the same four numbers gets old fast, and because pasting a colleague's real card into a staging environment is a terrible idea.
How to Use This Tool
- Pick a network. Choose Visa, Mastercard, Amex or any other brand, or leave it on Random to mix them.
- Choose an issuing bank and a quantity. The bank sets the card's look and color; the quantity chips jump straight to 1, 5, 10, 20 or 50.
- Decide what to include. Toggle the cardholder name, expiry and CVV on or off, and switch the number between spaced and unspaced.
- Press Generate. The card preview and the results table fill instantly. Click any row to load that card into the preview, or click the card to flip it and read the CVV.
- Take it with you. Copy a single number, copy every card, export to JSON, CSV, XML or SQL, or save the card as a PNG image for a mockup or bug report.
Need finer control? Open Advanced options to set a fixed cardholder name, force a specific BIN prefix, or lock the expiry to an exact month and year.
Common Use Cases
People reach for a card generator far more often than you would think:
- Testing checkout and payment forms: Developers verify that field validation, card-type detection and error states behave before touching a real gateway.
- QA and automated tests: Testers seed forms and end-to-end suites with fresh, valid-format cards instead of hard-coding the same one everywhere.
- Building demos and UI mockups: Designers drop a good-looking card into a prototype, screenshot or pitch deck — the Save image button makes that a one-click job.
- Populating databases: Anyone building sample data can export a batch to CSV or SQL and load it straight into a test table.
- Learning how cards work: Students and curious developers explore BIN ranges, card lengths and the Luhn checksum with real, inspectable examples.

Frequently Asked Questions
Are these credit card numbers real?
No. They are randomly generated to follow the format rules of each card network and to pass the Luhn checksum, but they are not issued to anyone and have no money, credit line or bank account attached. A payment processor will accept the format and then decline the card the moment it tries to authorize it, because the account simply does not exist.
Can I use them to actually buy something?
No, and you should not try. There is nothing to charge against, so any real purchase attempt will fail. More importantly, using generated numbers to attempt real transactions or passing them off as genuine cards is fraud. These are strictly for testing software you have permission to test.
What does Luhn-valid mean?
The Luhn algorithm is a simple checksum, invented in the 1950s, that catches most accidental typos in a card number. The last digit is a check digit calculated from the others; if the whole number does not add up correctly, validators reject it right away. Our generator computes that check digit for every card, which is why they pass client-side and library-level validation.
Which card networks and details can I generate?
You can generate Visa, Mastercard, American Express, Discover, JCB, Diners Club, UnionPay, Maestro and RuPay numbers, each using that brand's real BIN prefixes and correct length — 15 digits and a 4-digit code for Amex, for example. Alongside the number you get a matching CVV, a future expiry date and a cardholder name, and you can turn any of those off.
Can I export the cards or save the card image?
Yes. You can copy a single number, copy every generated card at once, or download the whole batch as JSON, CSV, XML or SQL. The Save image button renders the on-screen card — front or back — to a high-resolution PNG, which is handy for mockups, documentation and bug reports.
Is anything sent to a server or stored?
No. Everything runs in your browser with JavaScript, using your device's built-in cryptographic random generator. Nothing you generate is uploaded, logged or saved anywhere, and the tool keeps working offline once the page has loaded.
Why do some tools call this a fake or dummy credit card generator?
Those are just other names for the same thing — "test", "fake" and "dummy" all point to the fact that the numbers are not real. Whatever you call it, the purpose is identical: give developers and testers realistic, throwaway card data so they never have to use a genuine card while building and checking payment features.
