What is the Luhn Check Algorithm?

The Luhn Check Algorithm, also known as the Luhn Formula or Mod 10 Algorithm, is a simple checksum formula used to validate a variety of identification numbers, most notably credit card numbers. It checks the card number for any errors and ensures that it is correctly formatted.

Luhn Algorithm Example

Key Features of the Luhn Check Algorithm Test

• Validate credit card numbers easily
• Check for incorrect formatting
• Identify invalid card numbers
• Simple and effective
• Works with other identification numbers

How Does It Work?

The Luhn Check Algorithm works by summing the digits of the card number. It then applies a specific algorithm to double the value of every second digit and adds these to the sum. If the total modulo 10 is 0, the card number is valid.
