Disclaimer: These numbers are for testing and development purposes only. They are generated using the Luhn algorithm to appear valid but do not represent actual accounts or financial instruments.
How to Use the Credit Card Generator
Select the desired credit card network (Visa, Mastercard, Amex, Discover, or JCB).
Choose how many dummy cards you want to generate and select your preferred output format (New Line, CSV, or JSON).
Click "Generate Card Numbers" to instantly create mathematically valid dummy details for testing.
Features & Capabilities
Luhn Algorithm Valid
All generated card numbers mathematically pass the Luhn algorithm check (Modulus 10), allowing them to bypass basic frontend validation scripts during testing.
Bulk Data Formats
Export your dummy data precisely how your database needs it. Download the batch as formatted CSV for spreadsheets or raw JSON for automated test seeding.
Full Profile Generation
Beyond just the 16-digit PAN, the tool generates realistic cardholder names, future expiration dates, and network-accurate CVV codes (e.g., 4 digits for Amex).
100% Privacy Preserved
The generation process occurs entirely locally within your browser. The dummy profiles are never logged or stored on external servers.
Frequently Asked Questions
Can I use these numbers to buy things?
No. These are "dummy" or "fake" credit card numbers. While they look real and pass algorithmic formatting checks, they are not linked to any real bank accounts and have no monetary value. Any transaction attempt will be declined by payment gateways.
What is the Luhn Algorithm?
The Luhn algorithm, or modulus 10 formula, is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers and IMEI numbers. It prevents accidental errors (like typos) but does not protect against malicious attacks.
