How the passport number format works
- Format
- 1 uppercase letter followed by 8 digits
- Example
- G20693408
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Mexican passport numbers always start with a letter — despite some informal claims of an all-digit format, every documented real-world example uses letter + 8 digits
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z][0-9]{8}$A Mexican passport number is 1 uppercase letter followed by 8 digits, e.g. G20693408, issued by the Secretaría de Relaciones Exteriores (SRE), Mexico’s foreign ministry, through its network of delegations and consulates. Every documented real-world example follows this letter-first pattern — some informal sources online describe an all-digit format, but that claim isn’t backed by an actual passport number, so this checker doesn’t accept it.
What this checker verifies
This tool confirms the input is exactly 1 letter followed by 8 digits, catching an obvious typo like a missing digit or a number where the leading letter should be.
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. A pass doesn’t confirm the SRE 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 Mexican passport number look like?
1 uppercase letter followed by 8 digits, e.g. G20693408, issued by Mexico's Secretaría de Relaciones Exteriores (SRE).
Are there Mexican passports with an all-digit number?
Every documented real-world example uses a leading letter plus 8 digits, despite some informal claims of an all-digit format circulating online — this checker follows the letter-plus-digits pattern that's actually corroborated.
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 SRE's own records.
