Check digit
None enforced. Austria uses an internal check procedure not publicly documented; we deliberately do not reject on it.
Vatline does not reject on this check. Only the structure is enforced, so a format-valid number can still turn out to be unregistered. Rejecting a genuine customer costs more than one extra lookup.
Watch out for
- Austria publishes no public check key; a format-valid number can still be unregistered.
