German tax identification number (Steuer-ID, IdNr.)

ID steuerid

DatatypePersonal data (PII)identifier

Steuerliche Identifikationsnummer (IdNr., Steuer-ID), the personal tax number that the Federal Central Tax Office (BZSt) assigns once to every person registered in Germany and that stays the same for life. It has 11 digits that are chosen at random and hold no personal data. The first digit is never 0; in the first ten digits one digit occurs twice (since 2016 also three times, never three in a row) and the others at most once. The last digit is an ISO 7064 MOD 11,10 check digit. It is often printed in groups, as in 36 574 261 809. It is not the Steuernummer that a tax office gives.
