India Passport Number
Detects Indian passport numbers issued by the Ministry of External Affairs. The standard format is a single letter (A-Z excluding Q, X and Z, which are not used as the leading character) followed by 7 digits, sometimes printed with a space between the letter and the digits (e.g. 'K1234567' or 'K 1234567'). Corroborative keyword proximity is strongly recommended because the body is only 7 digits.

- Confidence justification
- Medium confidence: the single-letter prefix plus 7 digits is short and overlaps with many reference codes and serial numbers. Corroborative passport keywords within 300 characters are essential for reliable detection.
