Credit Card Generator
Use this tool to generate fake credit card numbers for testing payment systems. These numbers follow the correct format and pass Luhn checks but are not real credit cards.
About Fake Credit Card Numbers for Testing
Our fake credit card number generator for testing creates valid test credit card numbers that follow the correct format and pass the Luhn algorithm check. These numbers are specifically designed for software testing and development purposes.
Why Use Test Credit Card Numbers?
Developers and testers need valid credit card numbers that pass basic validation checks when:
- Testing payment processing systems
- Developing e-commerce applications
- Creating demo versions of financial software
- Validating form inputs without using real card data
- Performing security testing (with proper authorization)
Common Test Credit Card Number Patterns
Different card issuers have specific number patterns that our generator follows:
Frequently Asked Questions
Yes, all generated numbers pass the Luhn algorithm check (mod 10 check) which is the basic validation used by payment systems. However, they are not connected to real accounts and cannot be used for actual transactions.
No, these are test numbers only. They will be rejected by payment processors if attempted for real transactions. Our fake credit card number generator for testing is strictly for development and testing purposes.
The Luhn algorithm (or mod 10 algorithm) is a simple checksum formula used to validate identification numbers, especially credit card numbers. Our generator creates numbers that pass this validation.
This tool generates only the card numbers. For complete test card details including expiration dates and CVV, you would need to use specific test credentials provided by payment processors like Stripe or PayPal in their sandbox environments.
Generating test numbers for legitimate development and testing purposes is legal. However, using fake numbers with intent to commit fraud is illegal. Always use this tool responsibly and only in authorized testing environments.
How to Use Generated Credit Card Numbers
When testing payment systems with our fake credit card number generator for testing, follow these best practices:
For Developers
- Use in sandbox or test environments only
- Never commit test card numbers to production code
- Combine with test expiration dates (usually 12/99 or future dates)
- Use test CVV codes (any 3 digits for Visa/MC, 4 digits for Amex)
For QA Testers
- Verify form validation accepts valid card numbers
- Test with invalid numbers to ensure proper error handling
- Check how the system handles different card types
- Validate length restrictions for each card type
Payment Processor Testing
For more comprehensive payment testing, consider using the sandbox environments and specific test card numbers provided by payment processors:
- Stripe test cards
- PayPal sandbox
- Braintree test cards
- Authorize.Net test environment
