The authority said it took steps after discovering the tax number, 121212-1212, was used by hospitals and clinics to teach healthcare staff how to work different databases, the Swedish news agency TT reported Wednesday.

"If we hadn't blocked it, a newborn could have ended up with a load of incorrect health information tied to their ID number," Tax Agency spokesperson Ingegerd Widell said.
