How the passport number format works
- Format
- 8 alphanumeric characters (letters exclude I and O to avoid confusion with digits); passports issued before November 2022 used a fixed "X" + 7 digits pattern, current passports have no fixed internal structure
- Example
- X1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Passports issued since the October 2022 redesign deliberately have no fixed letter/digit structure within the 8 characters, as an anti-fraud measure — this check accepts the full alphanumeric range minus I/O
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-HJ-NP-Z0-9]{8}$A Swiss passport number is 8 alphanumeric characters, using letters other than I and O (to avoid confusion with digits) mixed with digits, and issued by the Federal Office of Police (fedpol). Passports issued before the October 2022 redesign followed a fixed pattern — an “X” followed by 7 digits, e.g. X1234567 — but current passports deliberately abandon any fixed internal structure within those 8 characters, a design choice fedpol adopted specifically to make the number harder to forge by pattern-matching.
What this checker verifies
This tool confirms the input is exactly 8 characters drawn from the permitted letters and digits (excluding I and O), which covers both the older fixed-pattern numbers and the newer structure-free ones.
What a pass doesn’t confirm
Because current Swiss passport numbers have no fixed internal pattern by design, this checker can’t verify anything beyond character set and length — there’s no positional rule or check digit left to recompute. A pass doesn’t confirm fedpol 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 Swiss passport number look like?
8 characters drawn from letters (excluding I and O) and digits, e.g. X1234567 for older-style documents, issued by the Federal Office of Police (fedpol).
Why don't newer Swiss passports follow a fixed letter-digit pattern?
Passports issued before the October 2022 redesign used a fixed "X" plus 7 digits pattern. Current passports deliberately have no fixed internal structure within the 8 characters, as an anti-fraud measure — this checker accepts the full permitted alphanumeric range.
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 fedpol's own records.
