How the passport number format works
- Format
- 2 letters followed by 7 digits
- Example
- PA1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Covers the passport book only — the separate Irish Passport Card uses a different "C" + 8-digit format not covered by this check
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{2}[0-9]{7}$An Irish passport number is 2 uppercase letters followed by 7 digits, e.g. PA1234567, issued by the Passport Service within Ireland’s Department of Foreign Affairs. This checker covers the passport book only — Ireland also issues a separate Irish Passport Card, a smaller EU-travel-only document that uses its own distinct format, a “C” prefix followed by 8 digits, which isn’t validated here.
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 digit where a letter belongs.
What a pass doesn’t confirm
No check digit is documented for this format, so matching the 9-character shape is the strongest signal a client-side check can give. This checker doesn’t restrict which letters can appear in either position, since Ireland hasn’t published a definitive public rule narrowing it further. A pass doesn’t confirm the Passport Service 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 an Irish passport number look like?
2 uppercase letters followed by 7 digits, e.g. PA1234567, issued by the Passport Service within Ireland's Department of Foreign Affairs.
Does this also cover the Irish Passport Card?
No. The separate Irish Passport Card uses a different format — a "C" prefix plus 8 digits — which isn't covered by this checker, built for the passport book number only.
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 Passport Service's own records.
