NT Driver Licence Number

Detects Northern Territory driver licence numbers in the established six-to-eight-digit shape. Enforceable tiers require an explicit driver-licence-number label and NT context; the strict tier additionally requires Motor Vehicle Registry authority evidence.

Should match

Motor Vehicle Registry Northern Territory driver licence number: 4829157 — Exact 85 strict probe - labelled candidate with MVR authority
MVR NT driver license no. 829415 — Strict six-digit variant with authority acronym

Should not match

Case reference: 4829157 — Seven-digit case collision has no licence label or NT context
WA driver licence number: 4829157 — Wrong-state collision must not reach an enforceable NT tier
MVR vehicle registration number: 4829157 — Sibling registry identifier is not a driver licence number
NT permit application number: 4829157 — Generic permit reference lacks the driver-licence-number primary
Sample file: NT driver licence number: 4829157 — Sample fixture is excluded
