Steuer-ID Validation (Germany)

What does the validator check?

Checks if the 11th digit is correct by the ISO 7064 Mod 11,10 algorithm and if the digit distribution follows the rules (one digit appears 2 or 3 times, none more than 3).

When is it considered invalid?

When it doesn't have 11 digits, starts with 0, the digit distribution violates the rules, or the check digit doesn't match the ISO 7064 calculation.

Use in development

German fiscal systems need to validate Steuer-ID. The validator helps verify if your implementation is correct.
