How the passport number format works
- Format
- 2 letters followed by 7 digits
- Example
- TZ1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- The 2-letter prefix is not case-sensitive on the document itself, though this check normalizes input to uppercase
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{2}[0-9]{7}$A Japanese passport number is 2 letters followed by 7 digits, e.g. TZ1234567, issued by Japan’s Ministry of Foreign Affairs (外務省, Gaimusho) through passport offices nationwide. The 2-letter prefix varies with the issuing office and passport type rather than following a single nationwide rule, and this checker normalizes whatever case you type into uppercase before matching, since the printed prefix isn’t meaningfully case-sensitive.
What this checker verifies
This tool confirms the input is exactly 2 letters followed by 7 digits, catching an obvious typo like a missing digit or a stray character carried over when the number is retyped from a scan of the passport’s data page.
What a pass doesn’t confirm
No check digit is documented for this format, so a correctly shaped 9-character string is the limit of what a browser-only check confirms. This checker doesn’t validate the 2-letter prefix against a specific list of issuing offices, since Japan hasn’t published one. A pass doesn’t confirm the Ministry of Foreign Affairs actually issued that number, that the passport is unexpired, or that it belongs to a real holder, and nothing you type is decoded or stored.
Scope: format-only validation, running entirely in your browser.

passport number FAQ
What does a Japanese passport number look like?
2 letters followed by 7 digits, e.g. TZ1234567, issued by Japan's Ministry of Foreign Affairs (外務省, Gaimusho).
Does letter case matter when I type it in?
No. This checker normalizes input to uppercase before matching, since the prefix isn't meaningfully case-sensitive on the document itself.
Does this confirm the passport is valid?
No. It only checks the 9-character shape. Confirming the passport was actually issued or is currently valid requires the Ministry of Foreign Affairs' own records.
