Mexico Passport Number
Detects Mexican passport numbers issued by the Secretaría de Relaciones Exteriores (SRE). Older passports use a single letter followed by 7-8 digits; newer books carry an 8-9 character alphanumeric serial. Because the format is short and loosely structured, corroborative keyword proximity is strongly recommended to reduce false positives.

- Confidence justification
- Medium confidence: the alphanumeric body is only 8-9 characters and lacks a fixed prefix, so the pattern can match unrelated reference codes and serial numbers. Corroborative passport keywords within 300 characters are essential for reliable detection.

Known false positives
