1. Test Data Disclaimer

Every number produced by this site is generated by an algorithm from random digits. It is not drawn from any database, leak, breach, or list of real cards. No real cardholder data of any kind exists on this website or on our servers.

To be precise about what “generated by an algorithm” means: when you press Generate, your browser picks a card network, reads its published length and prefix range, fills the remaining positions with random digits, then computes the final digit so the string satisfies the Luhn checksum. Expiry dates, CVV values, and names are produced the same way.

There is no lookup step and no source list. The site ships no dataset of card numbers because it does not need one: output is computed on the spot from randomness and a public formula. If two people generate the same number by coincidence, that is arithmetic, not a leak.

None of it reaches us either — generation runs entirely in your browser and the numbers are never transmitted to or logged by our servers. The Privacy Policy explains how to verify that with your browser’s developer tools.

2. These Numbers Do Not Work for Payments

Not “should not” — cannot. The reason is structural, not a restriction we chose to impose.

Authorisation requires an issuer, and there is no issuer. For a payment to be approved, the number must correspond to a live account on the books of the bank that issued it. The issuer is the only party that can say yes: it checks that the account exists, that the card is active and not reported lost, that the expiry date and security code match its records, and that the funds or credit line cover the amount. A number invented by a JavaScript function on your machine was never registered with any bank, so none of those checks can begin.

Luhn is a typo check, not a security check. The Luhn algorithm is a checksum published in 1960 and standardised in ISO/IEC 7812. Its purpose is to catch a mistyped or transposed digit before a request is sent anywhere. It involves no secret, no key, and no contact with a bank — any competent programmer can compute a Luhn-valid number in a few lines of code, which is exactly what this site does. Passing the check tells you the string is well formed, and nothing more. Our guide to the Luhn algorithm works through the arithmetic.

What actually happens if one is submitted. The merchant sends the details to its acquirer, which routes the request over the card network to the issuer identified by the number’s first digits. If that BIN maps to no issuer, routing fails. If it maps to a real issuer, that issuer looks up the account, finds nothing, and declines — typically “invalid card number” or “do not honour”. The attempt is logged, and repeated attempts look like card testing to fraud systems.

The short version: Luhn validity means “correctly formatted”, not “real”. A well formed address for a house that was never built is still an address, and the post still comes back. Our FAQ answers the questions that come up most often.

3. No Affiliation

CC Generator is independent. We are not affiliated with, endorsed by, sponsored by, or officially connected to Visa, Mastercard, American Express, Discover, JCB, Diners Club, Troy, UnionPay, Maestro, or any bank, card network, payment processor, gateway, or financial institution.

All product names, trademarks, and registered trademarks are the property of their respective owners. We use them only nominatively — to identify which published number format a generator produces. No endorsement or partnership is implied by their appearance here.

The guides, explanations, and reference material on this site are educational. They are not financial, legal, accounting, tax, or regulatory compliance advice, and reading them creates no professional relationship.

In particular, nothing here is guidance on PCI DSS compliance. Whether your systems fall in scope depends on your architecture and your acquirer’s requirements — consult a Qualified Security Assessor (QSA) or your acquiring bank. Using synthetic test data is good practice, but does not by itself put a system out of scope.

5. Accuracy of Technical Information

BIN ranges, number lengths, network prefixes, and validation rules change: networks reassign ranges, add new ones, and retire old ones. We keep this site current as best we can, but make no warranty that any format or rule shown here reflects the current published specification at the moment you read it.

For anything that matters, verify against primary sources:

  • ISO/IEC 7812 — the standard defining the structure of issuer identification numbers and primary account numbers.
  • EMVCo — https://www.emvco.com/ — chip, contactless, tokenisation, and 3-D Secure specifications.
  • PCI Security Standards Council — https://www.pcisecuritystandards.org/ — PCI DSS and related standards for handling cardholder data.

Your payment provider’s own documentation is the authority on how that provider behaves.

6. Use Official Sandbox Cards for Gateway Testing

The numbers here are for testing your own software: input validation, formatting, card brand detection, error states, and test fixtures. They are not tied to any processor’s sandbox, so they cannot exercise processor behaviour.

To test approvals, declines, reason codes, partial captures, refunds, chargebacks, or 3-D Secure challenge flows, use the official test cards your gateway publishes — Stripe, Adyen, PayPal, Braintree, Checkout.com, İyzico and others maintain their own, wired to rehearsed outcomes in their sandboxes. Each provider publishes its list in its own developer documentation.

7. User Responsibility

You are responsible for how you use anything generated here and for complying with the laws of your own jurisdiction. Laws on payment card data, computer misuse, and fraud differ by country, and some cover the possession or supply of card data in circumstances you might not expect.

Permitted and prohibited uses are set out in the Terms of Service. If you are unsure whether a use is lawful where you are, take local legal advice first.

8. Reporting Misuse

We built this as an engineering tool and intend it to stay one. If you see this site promoted for fraud, referenced in a scam, embedded in a phishing page, or otherwise misused, tell us:

Email: [email protected]

Include a link or screenshot if you can. We investigate every report, block access where we can, and cooperate with lawful requests from payment networks and law enforcement.

This site links to standards bodies, payment provider documentation, and other third-party resources. We do not control those sites and are not responsible for their content, accuracy, availability, or practices. A link is not an endorsement, and following one takes you outside the scope of our Terms of Service and Privacy Policy.

10. Advertising

This site displays advertising through Google AdSense, which is what keeps it free to use. Ads are selected and served by Google and its partners, not by us. We do not review, endorse, or vouch for advertised products or services, and an ad appearing here implies no relationship between the advertiser and CC Generator — any dealing with an advertiser is between you and them. Ads are kept visually separate from the generator and never styled to look like part of the tool.

How advertising cookies work, and how to opt out of personalised ads, is covered in the Privacy Policy.
