Germany TIN validator
Review the expected Germany Steuer-IDstructure before you save it, send it to an API, or include it in a tax workflow. Interactive validation appears only after this country's rules pass authoritative-source verification.
Private by design
Transient validation, no public history
TINs are sent securely to the canonical validation API, processed in real time, and not persistently stored by the public checker.
How Germany tax IDs are formatted
In Germany, the tax identifier is commonly known as Steueridentifikationsnummer (Steuer-ID). The expected format is 11 digits (XX XXX XXX XXX); official rules include a mod-11 check digit. Teams usually need a Germany Steuer-ID check around steuererklärung (tax return), lohnsteuerbescheinigung, banking, or before a record moves into billing, onboarding, or compliance review.

How to check a Germany Steuer-ID
Use this check before a record reaches billing, tax reporting, or manual review.
Enter the Steuer-ID
Paste or type the Germany tax identifier exactly as it appears in your source record. Spaces and separators are fine when they are part of the expected format.
Review the format result
Check whether the number matches the Germany syntax currently implemented here. The result does not query a tax-authority registry or confirm ownership.
Confirm important records
For onboarding, tax reporting, or compliance work, treat the result as a data-quality signal and confirm high-risk records with Bundeszentralamt für Steuern or your internal process.
