Built for testing & development

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.

  1. BIN Input - Provide a Bank Identification Number pattern (use 'x' for random digits)
  2. Card Generation - Tool generates numbers that pass Luhn algorithm
  3. Expiration Dates - Specify fixed dates or use random future dates
  4. CVV Codes - Generates appropriate CVV based on card type
  5. Validation - All cards are mathematically validated

Important Legal Notice
  • All generated numbers are fictional and cannot be used for real transactions
  • Using generated numbers for fraud is illegal and strictly prohibited
  • This tool should only be used in controlled testing environments
  • By using this tool, you agree to use it responsibly

What is a BIN pattern?

A BIN (Bank Identification Number) is the first 6–8 digits identifying the issuing bank. You can use x in the generator to represent random digits.

Why do generated cards pass validation?

All generated cards pass the Luhn algorithm check, which is the standard mathematical validation used for credit card numbers.

Can I use these cards for purchases?

No. These cards are randomly generated for testing purposes and are not linked to real bank accounts.

What card types are supported?

Visa, MasterCard, American Express, Discover, and Diners Club card formats are supported.

Is this tool safe to use?

Yes. This tool runs entirely in your browser and does not store or send any data. It is designed only for development and testing purposes.

What is a credit card generator?

A credit card generator is a tool that creates card numbers that follow valid formats and pass the Luhn algorithm, making them useful for testing payment systems and applications.

CC Generator: Free Test Card Number Tool for Developers

Our advanced credit card generator tool provides developers, testers, and QA 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 form validation. According to IBM's 2024 Cost of a Data Breach Report, testing in isolated environments reduces breach costs by up to 10%, making tools like this essential for secure payment development workflows.

Why Use Our Generator?

  • Luhn Algorithm Validated - All cards pass ISO/IEC 7812-1 mathematical validation
  • Multiple Card Types - Visa, MasterCard, Amex, Discover, Diners, JCB, UnionPay
  • Custom BIN Patterns - Create cards with specific Bank Identification Numbers
  • Safe for Testing - Cannot be used for real transactions, runs client-side only
  • Co-Branded Support - Detects multiple networks for co-branded card patterns
Important: All generated numbers are for testing purposes only. They are not real cards and cannot be used for fraudulent transactions.

What is a Credit Card Generator?

A credit card generator creates valid test card numbers that follow the Luhn algorithm and proper card network formats defined by ISO/IEC 7812. The Luhn algorithm, developed by Hans Peter Luhn in 1954, is the checksum formula used to validate identification numbers across payment networks including Visa, Mastercard, and American Express. This tool is designed for testing payment systems, development environments, and QA automation — not for fraudulent use. Using synthetic test data in development environments prevents exposure of real customer payment information, as recommended by the OWASP Tokenization Guidelines.

How It Works

The generator follows a deterministic process to produce valid card numbers:

  1. Select Network: Choose Visa, Mastercard, Amex, Discover, or enter a custom BIN pattern using 'x' for random digits
  2. Configure: Set expiry month/year, CVV, quantity (1-1000), and output format (pipe, comma, JSON, card-only, formatted)
  3. Generate: Tool produces card numbers with correct Luhn checksum digit, using cryptographically secure random number generation via crypto.getRandomValues
  4. Export: Copy results to clipboard, download as .txt/.json file, or clear and regenerate as needed

Common Use Cases

Developers and testers use this tool across various workflows:

  • Payment Form Testing: Validate checkout forms with realistic test data across all card networks
  • QA Automation: Bulk generate test datasets for CI/CD pipelines and automated testing scripts
  • Development: Test payment integration logic (Stripe, PayPal, Square) without real cards or sandbox credentials
  • Education: Learn about card number structure, BIN patterns, and the Luhn algorithm for computer science coursework
  • Data Migration: Generate test datasets for migrating payment systems between platforms
