Credit Card Generator FAQs
Common questions about generating test credit card numbers
What is a test credit card number?
A test credit card number is a number that follows the same structure and validation rules as real credit cards (using the Luhn algorithm) but is not associated with any actual account. These numbers are used for development and testing purposes only.
Can I use these numbers for real transactions?
No, absolutely not. These are test numbers only and cannot be used for actual purchases or transactions. They are designed solely for development, testing, and educational purposes.
What is the Luhn algorithm?
The Luhn algorithm (also known as the "modulus 10" algorithm) is a checksum formula used to validate credit card numbers. It ensures that the card number follows a specific mathematical pattern that can be verified.
Why do different card types have different lengths?
Different card networks use different number formats. Visa and Mastercard typically use 16 digits, American Express uses 15 digits, and Discover uses 16 digits. Each type also has specific prefixes (like 4 for Visa, 5 for Mastercard).
How are CVV codes generated?
CVV (Card Verification Value) codes are randomly generated 3-digit numbers (or 4 digits for American Express). In real cards, CVVs are cryptographically generated, but for test purposes, random numbers are sufficient.
Are the expiry dates real?
The expiry dates are randomly generated future dates (typically 1-5 years in the future) to ensure they appear valid for testing purposes. They are not associated with any real card.
Is my data sent to a server?
No, all credit card generation is performed client-side in your browser. No data is sent to any server, ensuring complete privacy and security.
Can I generate multiple cards at once?
Currently, the tool generates one card at a time. You can click "Generate New Card" multiple times to create different test cards as needed.
