How the passport number format works
- Format
- 2 letters followed by 6 digits
- Example
- EM123456
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- 8 characters total, distinct from Belgium's separate 11-digit National Register Number (RRN) used for other ID purposes
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{2}[0-9]{6}$A Belgian passport number is 2 uppercase letters followed by 6 digits, e.g. EM123456 — 8 characters total, issued by FPS Foreign Affairs (Federale Overheidsdienst Buitenlandse Zaken). It’s worth not confusing this with Belgium’s separate 11-digit National Register Number (RRN), the all-purpose identifier used for tax filings, social security, and other government interactions — the two numbers serve entirely different purposes and neither substitutes for the other.
What this checker verifies
This tool confirms the input is exactly 2 letters followed by 6 digits, catching an obvious typo like a missing digit or a digit count that’s off by one.
What a pass doesn’t confirm
No check digit is documented for this format, so matching the 8-character shape is the strongest signal a client-side check can give. A pass doesn’t confirm FPS 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 Belgian passport number look like?
2 uppercase letters followed by 6 digits, e.g. EM123456, issued by FPS Foreign Affairs (Federale Overheidsdienst Buitenlandse Zaken).
Is this the same as Belgium's National Register Number?
No. This 8-character passport number is separate from Belgium's 11-digit National Register Number (RRN), which is used for tax, social security, and other identification purposes, not travel documents.
Does a valid format confirm the passport is real?
No. It only checks the 8-character shape. Confirming the passport was actually issued or is currently valid requires FPS Foreign Affairs' own records.
