TIN Structure: The Taxpayer Identification Number (TIN) follows the format TIN = F || SEQ || K, where:

  • "F" is a fixed number, either 6 or 9.
  • "SEQ" represents 8 digits generated from a sequence of natural numbers (e.g., 00000001, 00000002).
  • "K" is a control number calculated using the algorithm described below.

The TIN is composed of a ten-digit number N9N8N7N6N5N4N3N2N1K, where the tenth digit (K) serves as the control number.

To validate the correctness of the taxpayer's identification number, follow the algorithm outlined in steps 2-8:

  1. Extract digits N9 to N1 from the TIN.
  2. Multiply each digit by the corresponding number in the sequence 9, 8, 7, 6, 5, 4, 3, 2, 1, and sum the results: A = Σ(Ni * i), where i = 1,…,9.
  3. Divide the sum (A) by the two-digit number formed by the first two digits of the TIN (N9N8): B = A mod N9N8.
  4. If B < 10, set K = B. If B >= 10, add the individual digits of B: Z = Σ(Sm), where m is the position of the digit.
  5. If Z < 10, set K = Z. If Z >= 10, repeat the process of adding digits until Z < 10, and the final Z becomes the control number K of the TIN.
