About Credit Card Generator
Purpose of This Tool
The Credit Card Generator is a free web-based tool designed to help developers, testers, and educators generate valid test credit card numbers that can be used during development and testing processes of payment systems and applications.
When developing or testing applications that handle credit card payments, it's often necessary to use credit card numbers that pass validation checks but don't represent actual financial accounts. This tool fulfills that need by creating random but structurally valid credit card numbers.
Technical Details
All generated credit card numbers:
- Follow the standardized prefixes for each card type (e.g., Visa starts with 4)
- Contain the correct number of digits for the specific card type
- Pass the Luhn algorithm check (mod 10 check digit)
- Can be generated in various formats (JSON, XML, CSV) for easy integration
The generator creates numbers that will pass basic validation checks performed by payment processing systems, but they cannot be used to complete actual financial transactions as they are not connected to any actual accounts.
Supported Card Types
| Card Type | Prefix | Length |
|---|---|---|
| Visa | 4 | 13, 16, 19 |
| Mastercard | 51-55, 2221-2720 | 16 |
| American Express | 34, 37 | 15 |
| Discover | 6011, 644-649, 65 | 16, 19 |
| JCB | 3528-3589 | 16, 19 |
| Diners Club | 300-305, 36, 38-39 | 14, 16, 19 |
