  format 999-999-999-999V for customers and vendors subject to VAT, or 999-999-999-999N for customers and vendors not subject to VAT.

• https://www.ntrc.gov.ph/images/journal/j20141112a.pdf j20141112a.pdf (attached just in case) explains where TIN comes from, and also explains the TIN structure (originally retrieved from).

  The unique TIN consists of 9-12 digit numeric code. The first nine digits is the TIN proper and the last three digits is the branch code (in the case of business entities). The first digit thereof identifies the type of taxpayer. The digit zero ("0") signifies a corporation and digits 1 to 9 denote individual taxpayers. The succeeding 7 digits are sequential and the ninth digit is the check digit.

  In 1998, RMO 34-98 prescribed the procedures and guidelines to standardize the encoding of taxpayer's data. For individual taxpayers, TIN should be encoded in the nine-digit form of 123 - 456 - 789. If the last three characters (10th-12th digit) are not encoded, the default value should always be 000.

  In case of business entities, the TIN is usually encoded in the twelve-digit form (123-456-789-000), the last three digits of which stand for the branch code. It should be mentioned, however, that the BIR is soon to implement a thirteen-digit TIN for business entities which are operating with more than a thousand branches.

  Head office’s nine-digit TIN, plus a three-digit branch code

• According to https://github.com/arthurdejong/python-stdnum/files/3269661/VAT_by_Countries.pdf (attached to #124) it is called "Tax Identification Number" (short TIN) and it is 12 digits long (ex. xxx xxx xxx xxx).

  The TIN consists of 9-12 digits; the first nine digits are actual TIN, whereas the last three digits are the branch code (for corporate entities). But it is 000 for a singular citizen.

  The first nine digits or the original number of TIN identifies the citizenship category. TINs beginning with 1-9 refers to individuals. If a TIN starts with zero (0), it relates to a partnership business.
