About Test Credit Card Numbers

This tool generates valid credit card numbers that follow the correct format for different card types, but are not real cards that can be used for actual transactions.

Key Features

  • Valid Formats: Numbers follow the correct length and prefix patterns for each card type
  • Luhn Algorithm: All numbers pass the Luhn check (mod 10 algorithm)
  • Testing Purposes: For use in development, testing, and validation scenarios
  • No Real Value: These numbers cannot be used for actual purchases

When to Use Test Cards

  • Testing payment processing systems
  • Developing e-commerce applications
  • Validating credit card form inputs
  • Demonstrating payment flows
  • Education and training purposes
// Example: Validate a credit card number with Luhn algorithm function isValidCreditCard(number) { // Remove all non-digit characters number = number.replace(/\D/g, ''); // Check if empty or not all digits if (!number || !/^\d+$/.test(number)) return false; let sum = 0; let alternate = false; for (let i = number.length - 1; i >= 0; i--) { let digit = parseInt(number.charAt(i), 10); if (alternate) { digit *= 2; if (digit > 9) { digit = (digit % 10) + 1; } } sum += digit; alternate = !alternate; } return (sum % 10) === 0; }
