FAQ

What is the Luhn algorithm used for?

The Luhn algorithm, also known as the modulus 10 algorithm, is a checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, and various government ID numbers.

How are my inputs processed?

When you use these tools, your data is sent to Elysia Tools servers for processing. Text inputs are never stored, and any uploaded files are automatically deleted after 6 hours to ensure your privacy.

Can I validate multiple numbers at once?

Yes, many of our 6 Luhn tools support bulk processing, allowing you to verify or generate check digits for lists of numbers efficiently through our server-side infrastructure.
