How the passport number format works
- Format
- 3 letters followed by 6 digits
- Example
- PAA123456
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Older Spanish passports used a shorter 2-letter-prefix format that is no longer issued; this check covers the current 3-letter-prefix format
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{3}[0-9]{6}$A Spanish passport number is 3 uppercase letters followed by 6 digits, e.g. PAA123456, issued by the Cuerpo Nacional de Policía, part of Spain’s Dirección General de la Policía. That 3-letter prefix is a relatively recent standard — older Spanish passports used a shorter, 2-letter-prefix format that has since been retired, so a passport number matching the old shape won’t pass this checker even though it may still appear on an unexpired older document.
What this checker verifies
This tool confirms the input is exactly 3 letters followed by 6 digits, catching an obvious typo like a missing digit or a letter count that’s off by one — the kind of error that slips in when a number is retyped rather than copied from 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 targets the current 3-letter-prefix format specifically, so it deliberately doesn’t also accept the discontinued 2-letter style. 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 Spanish passport number look like?
3 uppercase letters followed by 6 digits, e.g. PAA123456, issued by Spain's Cuerpo Nacional de Policía under the Dirección General de la Policía.
Were Spanish passport numbers always this shape?
No — older Spanish passports used a shorter, 2-letter-prefix format that is no longer issued. This checker covers the current 3-letter-prefix format used on passports issued today.
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 Cuerpo Nacional de Policía's own records.
