    Function analyzeNTN

    • Analyzes a Pakistani National Tax Number (NTN).

      • Individuals use their 13-digit CNIC as their NTN (since the Finance Act 2015).
      • Companies and associations of persons have a 7-digit NTN, often written with an 8th check digit as 1234567-8.

      FBR does not publish the check-digit algorithm, so the check digit is not verified; this validates the format only.

      Parameters

      • ntn: string

        NTN in any common format

      Returns NTNInfo | null

      NTN details, or null if the format is invalid
