Test Credit Card Generator

Generate Luhn-valid test credit card numbers for QA with real brand prefixes (Visa, Mastercard, Amex, Discover, Diners, JCB).

⚠️
Test data only. Generated numbers pass the Luhn checksum and use real brand prefixes, but they are random, non-issued cards — they cannot be used for real transactions. This is the same practice Stripe and Mastercard document for their public test numbers.
CONFIG
Want to check a card number instead? Use the Credit Card Validator to run the Luhn check and detect the brand. Everything here runs locally in your browser.

Why Test Credit Card Generator?

Every QA engineer has typed 4242 4242 4242 4242 one too many times. This generator produces Luhn-valid card numbers across the real brand ranges - Visa, Mastercard, Amex, Discover, Diners, JCB - so your payment forms and validation logic get exercised properly instead of with the same two Stripe fixtures. Optional expiry and CVV round the rows out into full test records.

  • Numbers use real BIN prefixes and correct lengths per brand, so brand detection and format branches actually get tested.
  • Generated numbers are random and non-issued - keep them in test and staging environments, never in a live payment flow.
  • Use the CSV export to seed a test suite or fixture file in one step.
  • Pair it with the Credit Card Validator to confirm a generated number passes the Luhn check end-to-end.

What is Test Credit Card Generator?

Test Credit Card Generator creates Luhn-valid test card numbers for QA, form testing, and seed data. Numbers use real BIN/IIN brand prefixes (Visa, Mastercard, American Express, Discover, Diners Club, JCB) and pass the Luhn checksum, so they behave like real cards in validation logic — but they are random, non-issued test data and can never process a real transaction. You can optionally add a future expiry date and CVV. Everything runs in the browser.

Common Use Cases

Payment Form Testing

Fill checkout and payment forms with numbers that pass client-side validation (brand detection, length, Luhn) without using real card data.

QA Test Fixtures

Seed automated test suites and CI pipelines with realistic card numbers that exercise brand-specific format branches.

API Development

Test payment-gateway sandbox flows and webhook payloads with structurally valid card numbers.

Demo & Staging Data

Populate staging databases and demo environments with card data that looks production-like but is clearly fake.

How to Use This Tool

  1. Pick a brand (or "All brands") and how many cards you need

  3. Click Generate — every number is Luhn-valid with the correct brand prefix and length
