How the passport number format works
- Format
- 2 letters followed by 6 digits
- Example
- FZ123456
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- No official checksum digit is documented for this format, unlike Brazil's CPF/CNPJ tax IDs
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{2}[0-9]{6}$A Brazilian passport number is 2 uppercase letters followed by 6 digits, e.g. FZ123456, issued by the Polícia Federal, the agency responsible for both passport issuance and border control in Brazil. That’s worth contrasting with Brazil’s other major ID numbers: the CPF (individual taxpayer number) and CNPJ (company registry number) both carry well-documented check-digit algorithms, but no equivalent checksum has been published for the passport format.
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 letter typed where a digit belongs.
What a pass doesn’t confirm
Because no checksum is documented for this format — unlike CPF or CNPJ — matching the 8-character shape is the strongest signal a client-side check can give here. A pass doesn’t confirm the Polícia Federal 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 Brazilian passport number look like?
2 uppercase letters followed by 6 digits, e.g. FZ123456, issued by Brazil's Polícia Federal.
Does the passport number have a check digit like CPF does?
No. Unlike Brazil's CPF and CNPJ tax identifiers, which carry documented check-digit algorithms, no official checksum is published for the passport number format — this checker validates shape only.
Does this confirm the passport is valid?
No. It only checks the 8-character shape. Confirming the passport was actually issued or is currently valid requires the Polícia Federal's own records.
