What is a MasterCard Credit Card?
MasterCard is a global leader in payment processing, providing the technology that connects consumers, financial institutions, merchants, and governments. A MasterCard credit card number typically consists of 16 digits and always follows specific identification standards.
Understanding the structure of a MasterCard number is essential for payment gateway integration, security testing, and data validation.

Frequently Asked Questions
Is this a real credit card generator?
No. This tool generates mathematically valid numbers for testing and development purposes only. These cards cannot be used for actual purchases as they lack a real bank account connection.
What is the Luhn Algorithm?
Also known as the "modulus 10" algorithm, it is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers and IMEI numbers.
Does it support the new 2-series BINs?
Yes, our validator and generator are fully updated to support both the traditional 5-series (51-55) and the newer 2-series (2221-2720) MasterCard ranges.
Is my data safe here?
Completely. All validation and generation happens locally in your browser. We never transmit or store any card numbers you enter on our servers.
