How the passport number format works
- Format
- 9 alphanumeric characters: 2 letters followed by 7 more letters/digits, the last of which is always a digit
- Example
- AB1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Middle characters can be letters or digits, but the final character is always a digit
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{2}[A-Z0-9]{6}[0-9]$A Dutch passport number is 9 characters: 2 letters followed by 7 more characters that can mix letters and digits, e.g. AB1234567. Passports are issued through Dutch municipalities on behalf of the Ministry of Foreign Affairs, which is why the exact character mix in the middle varies more than in many other countries’ formats — but one rule holds regardless: the final character is always a digit, never a letter.
What this checker verifies
This tool confirms the input opens with 2 letters, allows either letters or digits through the next 6 characters, and requires the 9th and final character to be a digit — catching a typo like a letter mistakenly placed in that last position.
What a pass doesn’t confirm
No check digit is documented for this format, so matching the 9-character pattern, including the fixed trailing digit, is the strongest signal a client-side check can give. A pass doesn’t confirm the passport was actually issued, is unexpired, or 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 Dutch passport number look like?
9 characters: 2 letters followed by 7 more characters that can be letters or digits, e.g. AB1234567, issued via Dutch municipalities on behalf of the Ministry of Foreign Affairs.
Is there a rule for the very last character?
Yes — regardless of what the middle characters are, the final character of a Dutch passport number is always a digit, never a letter.
Does a valid format confirm the passport is real?
No. It only checks the 9-character shape. Confirming the passport was actually issued or is currently valid requires the issuing municipality's own records.
