Free Credit Card Generator for Testing & Development

Our advanced credit card generator tool provides developers, testers, and quality assurance teams with valid test card numbers that pass Luhn algorithm validation. Generate unlimited test credit card numbers with custom BIN patterns for payment gateway testing, e-commerce development, and financial application testing.

Why Use Our Credit Card Generator?

  • Luhn Algorithm Validated - All generated cards pass mathematical validation checks
  • Multiple Card Types - Support for Visa, MasterCard, American Express, Discover, and Diners Club
  • Custom BIN Patterns - Create cards with specific Bank Identification Numbers
  • Safe for Testing - Generated numbers work for testing but cannot be used for real transactions
  • Developer Friendly - Multiple output formats including JSON, CSV, and pipe-delimited

How to Generate Test Credit Card Numbers

  1. Enter your desired BIN pattern (use 'x' for random digits)
  2. Select expiration date preferences or use random future dates
  3. Choose CVV generation method
  4. Specify quantity and output format
  5. Click generate and copy/download your test cards

Common Use Cases

Our credit card number generator is essential for:

  • Payment gateway integration testing
  • E-commerce website development
  • Mobile payment app testing
  • Financial software quality assurance
  • Educational purposes and coding tutorials

Understanding BIN Patterns

A BIN (Bank Identification Number) is the first 6-8 digits of a credit card that identify the issuing bank and card type. Our tool allows you to create custom BIN patterns to generate cards that match specific testing requirements.

Important: All generated credit card numbers are for testing purposes only and cannot be used for actual financial transactions. This tool should only be used in development and testing environments.

This Credit Card Generator is a sophisticated utility tool designed for developers, testers, and educators who need valid credit card numbers for testing payment systems, e-commerce platforms, and financial applications.

The tool generates credit card numbers that pass the Luhn algorithm validation, making them suitable for testing scenarios where valid card numbers are required. All generated cards are completely fictional and cannot be used for actual transactions.

The generator uses the following process to create valid credit card numbers:

  1. BIN Input: You provide a Bank Identification Number (BIN) pattern. Use 'x' characters for random digits.
  2. Card Generation: The tool generates card numbers based on your BIN pattern while ensuring they pass the Luhn algorithm check.
  3. Expiration Dates: You can specify fixed expiration dates or use random future dates.
  4. CVV Codes: The tool generates appropriate CVV codes based on card type (3 digits for most cards, 4 digits for Amex).
  5. Validation: All generated cards are automatically validated using the Luhn algorithm to ensure they're mathematically correct.

Important Legal Notice

This tool is intended for legitimate testing and educational purposes only. Please be aware of the following:

  • All generated credit card numbers are fictional and cannot be used for actual financial transactions
  • Using generated card numbers for fraudulent activities is illegal and strictly prohibited
  • This tool should only be used in controlled testing environments
  • Always comply with local laws and regulations regarding financial data
  • Ensure you have proper authorization before testing payment systems

By using this tool, you agree to use it responsibly and only for legitimate purposes.

What is a BIN pattern?

A BIN (Bank Identification Number) pattern is the first 6-8 digits of a credit card that identify the issuing bank and card type. In this tool, you can use 'x' characters to represent random digits in your pattern.

Why do the generated cards pass validation?

All cards generated by this tool pass the Luhn algorithm check, which is the standard validation method used by payment processors to verify card number integrity.

Can I use these cards for online purchases?

No. These are randomly generated numbers that only pass mathematical validation. They are not associated with any real accounts and cannot be used for actual transactions.

What card types are supported?

The tool supports Visa, MasterCard, American Express, Discover, and Diners Club cards with appropriate BIN ranges and card lengths.

Is my data stored when using this tool?

The tool only stores your generation history locally in your browser for convenience. No data is sent to any server.
