Norway Passport Number

Detects Norwegian passport numbers issued by the police (politiet). The 2020 series uses a nine-character document number: ordinary (C) and emergency (K) passports are one prefix letter plus two characters that may be letters or digits plus six digits (specimen CCC002251); diplomatic (FG), service (FH), special (FJ), travel-document (FK) and foreigner (FL) passports are a two-letter prefix plus one letter-or-digit plus six digits. Pre-2020 series passports (in circulation until October 2030) carry an eight-digit document number.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: the 2020-series prefix-anchored nine-character shape is structurally distinctive, but the legacy eight-digit form is a plain digit run, so corroborating passport keywords are required on every tier and the legacy form is additionally held to a min-2-unique-terms evidence bar. recommended_confidence is the evidence-gated 75 workhorse tier per registry convention.

Proximity: 300 characters

Should match

Passport number CCC002251 was checked against the register by politiet — 2020-series ordinary passport number (national control-guide specimen) with label context
passnummer C1A123456 (norsk pass) — 2020-series ordinary passport with digit in the second position
FG1234567 — 2020-series diplomatic passport number (FG prefix)
Emergency travel: pass K2B654321 utstedt i dag — 2020-series emergency passport number (K prefix)
passport no. 28454393 (issued 2015, pre-2020 series) — Legacy eight-digit passport number

Should not match

CCC00225 — Eight characters in the 2020-series form — one digit short
ABC123456 — Nine characters but the prefix letter A is not an issued Norwegian passport series
ccc002251 — Lowercase — passport numbers are printed uppercase (pattern is case-sensitive)
FM1234567 — FM is not an issued two-letter prefix (only FG, FH, FJ, FK, FL)
284543931 — Nine digits — too long for the legacy eight-digit form and not a valid 2020-series shape

Known false positives

Eight-digit runs such as dates written as DDMMYYYY, invoice or order numbers can match the legacy form. Mitigation: The legacy regex is only exported in a 75 tier requiring two unique passport-evidence terms plus the template-exclusion NOT-group; AllDigitsSameFilter suppresses repeated-digit placeholders.
Nine-character product or serial codes beginning with C, K or F could match the 2020-series form. Mitigation: Every tier requires passport keywords within the 300-character proximity window; the prefix letters and trailing six-digit block keep the collision surface small.
