How the passport number format works
- Format
- 1 uppercase letter followed by 7 digits
- Example
- K1234567
Things to watch for
- Format-only check — does not confirm the passport was actually issued, is unexpired, or is currently valid
- Some newer e-passport formats have been reported informally but are not yet confirmed by an authoritative source, so this check covers the long-standing documented format only
- Validation runs entirely in your browser — the number you enter is never transmitted or stored
^[A-Z][0-9]{7}$An Indian passport number is 1 uppercase letter followed by 7 digits, e.g. K1234567, issued through Passport Seva, the Ministry of External Affairs’ online passport application and issuance platform that replaced the older, largely manual regional passport office process.
What this checker verifies
This tool confirms the input is exactly one letter followed by 7 digits, catching a common slip like a missing digit or a letter typed where a digit belongs — the kind of error that creeps in when a number is retyped from a printed application acknowledgment 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 8-character string is the limit of what a browser-only check can confirm. India has been reported, informally, to be moving toward chip-based e-passports with a different numbering convention, but no authoritative specification of that new format was available to build against — this checker deliberately covers only the long-established format it can verify with confidence. A pass never confirms the passport was actually issued or is currently valid, and nothing you type is decoded or stored.
Scope: format-only validation, running entirely in your browser.

passport number FAQ
What does an Indian passport number look like?
One uppercase letter followed by 7 digits, e.g. K1234567, issued through Passport Seva, the Ministry of External Affairs' passport service.
Does this cover India's newer e-passports too?
This checker covers the long-standing, well-documented letter-plus-7-digit format. Some newer e-passport numbering has been reported informally but isn't yet confirmed by an authoritative source, so it isn't separately modeled here.
Does a correct format mean the passport is valid?
No. It only confirms the shape is right. Confirming the passport was actually issued or is currently valid requires Passport Seva's own records.
