Types of TINs:

- 10-digit TINs shall be issued to enterprises and organizations that are legal persons; representatives of households, household businesses and other individuals;

- 13-character TINs shall be issued to dependent units and other entities;

Structure of TIN: N1N2N3N4N5N6N7N8N9N10 - N11N12N13


- The first two digits N1N2 indicate the province that issues TINs

- Each individual is issued 01 unique TIN to use throughout their whole life. Any dependant of that individual shall be issued with a TIN for the purpose of claiming personal exemption for personal income taxpayers. The TIN issued to the dependant is also his/her personal TIN, which is used when paying his/her tax;

- Enterprises, organizations and individuals responsible for deducting and paying tax on behalf of taxpayers shall be issued with separate TINs for use when deducting tax;

- Issued TINs shall not be reissued to another taxpayer;
