How the passport number format works
- Format
- 1 or 2 letters (issuing-office code) followed by 6-7 digits
- Example
- C1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Sources on Indonesia's exact digit count and letter position disagree in places, so this check intentionally covers a range (1-2 letters, 6-7 digits) rather than one overly precise pattern
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z]{1,2}[0-9]{6,7}$An Indonesian passport number is 1 or 2 letters, denoting the issuing office, followed by 6 or 7 digits, e.g. C1234567, issued by the Direktorat Jenderal Imigrasi (Directorate General of Immigration) under Indonesia’s Ministry of Law and Human Rights. Worth being upfront about here: publicly available sources on Indonesia’s exact letter and digit count don’t fully agree with each other, so this checker deliberately covers a documented range rather than a single overly precise pattern.
What this checker verifies
This tool confirms the input is 1 or 2 letters followed by 6 or 7 digits, which is a genuinely broad check by design — built to match what’s actually corroborated rather than a stricter shape that available sources can’t consistently confirm.
What a pass doesn’t confirm
Because sources disagree on the finer details of Indonesia’s format, this checker can’t validate beyond that general letter-and-digit range — there’s more precision here than any one public source reliably supports. A pass doesn’t confirm the Directorate General of Immigration 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 — and intentionally permissive given the inconsistent public documentation.

passport number FAQ
What does an Indonesian passport number look like?
1 or 2 letters denoting the issuing office, followed by 6 or 7 digits, e.g. C1234567, issued by Indonesia's Direktorat Jenderal Imigrasi (Directorate General of Immigration).
Why does this checker accept a range instead of one exact shape?
Public sources on Indonesia's exact letter count and digit count disagree in places, so rather than pick one source and risk being falsely precise, this checker intentionally covers the documented range — 1 or 2 letters, 6 or 7 digits.
Does a valid format confirm the passport is real?
No. It only checks the general shape. Confirming the passport was actually issued or is currently valid requires the Directorate General of Immigration's own records.
