Should match

• 123456789012 — Standard 12-digit Indonesian SIM number
• 987654321098 — Another valid 12-digit format
• 123456789013 — 12-digit number with leading zero

Should not match

• 12345678901 — Too few digits (11 instead of 12)
• 1234567890123 — Too many digits (13 instead of 12)
• template example placeholder record identifier — Template/sample context should be excluded even when anchor words are present

Known false positives

• Generic numeric sequences matching the driver's license format appearing in unrelated contexts. Mitigation: Require corroborative evidence keywords within the proximity window to confirm driver's license context.
