FAQ
Common questions
What is the corporate number?
The thirteen-digit identifier the National Tax Agency assigns to every corporation in Japan. It stays with the entity for life and is the number a profile call takes.
Is this the commercial registry?
The corporate number register is the national publication the tax side runs, and the commercial registries at the Legal Affairs Bureaus hold the filings behind it. The search reads the national corporate number register.
Can I search by company name?
Yes. The register is searched by name as well as by number, and a name returns the nearest candidates ranked, with their corporate number and status.
