In Germany, a tax ID (Steueridentifikationsnummer) is not the same as an SSN (Social Security Number) used in the United States. Every resident in Germany is assigned a unique 11-digit tax ID at birth or upon registration with the local authorities, which is used specifically for tax purposes and remains unchanged throughout one's life. Unlike the SSN, it's solely for tax identification and not used for other identification purposes.
