Fake Credit Card Generator
Generate Luhn-validated fake credit card numbers for testing—with CVV, expiry dates, and bulk export to CSV/JSON.
⚠️ For Testing Only
These are fake credit card numbers generated using the Luhn algorithm for development and testing purposes. They pass validation checks but cannot be used for real transactions and are completely safe.
Our Fake Credit Card Generator is a comprehensive free tool for creating Luhn-validated test credit card numbers for development and testing. Supporting 7 major card types (Visa, Mastercard, Amex, Discover, JCB, Diners Club, UnionPay), it generates complete card details including CVV codes and expiry dates. Perfect for developers, QA testers, and educators who need safe, realistic test data—all processed in your browser.
Common Use Cases for Fake Credit Cards

Understanding the Luhn Algorithm
The Luhn algorithm (modulus 10) is a checksum formula invented by IBM scientist Hans Peter Luhn. It validates credit card numbers by:
- Starting from the rightmost digit, double every second digit
- If doubling results in a number greater than 9, subtract 9
- Sum all the digits
- If the total modulo 10 equals 0, the number is valid
Example: Validating 4532015112830366
6*2=12→3, 6+3=9, 0+3=3, 3*2=6, 8+6=14, 3*2=6, 1+6=7, 1*2=2, 5+2=7, 1*2=2, 0+2=2, 2*2=4, 3+4=7, 5*2=10→1, 4+1=5
Sum = 70, 70 % 10 = 0 ✓ Valid

}Frequently Asked Questions
Are these real credit card numbers?
No! These are completely fake numbers generated using mathematical algorithms (Luhn algorithm). They pass validation checks but are NOT linked to any real bank accounts and CANNOT be used for purchases. They're purely for testing and development purposes.
Is it legal to use fake credit card numbers?
Yes, using fake credit card numbers for testing, development, and educational purposes is completely legal and encouraged. However, attempting to use them for real transactions, fraud, or any illegal activity is a serious crime. Always use these numbers only in test/sandbox environments.
What is the Luhn algorithm?
The Luhn algorithm (also called modulus 10 or mod 10) is a checksum formula used to validate credit card numbers. It detects accidental errors in card numbers by calculating a check digit. Our generator creates numbers that pass this validation, making them suitable for testing form validation logic.
Can I generate cards in bulk?
Yes! You can generate up to 50 fake credit cards at once. After generation, use the Bulk Export Options to download all cards in CSV, JSON, or plain text format. This is perfect for automated testing, seeding test databases, or creating comprehensive test datasets.
What card types are supported?
We support 7 major card types: Visa (starts with 4), Mastercard (starts with 5), American Express (starts with 34/37, 15 digits), Discover (starts with 6011), JCB (starts with 35), Diners Club (starts with 36, 14 digits), and UnionPay (starts with 62). Each has authentic formatting and CVV length.
Do the CVV and expiry dates work?
The CVV codes are randomly generated (3 digits for most cards, 4 for Amex) and the expiry dates are set 1-6 years in the future. While they look realistic, they're not validated against any real system. These are purely for visual testing and form validation, not actual payment processing.
