The national online e-student ID number is a student's personal identity code (19 digits) and a unified code for the basic information of the personnel in the education system. It consists of type code (1 digit), citizen identity number (18 digits) or personal identity self-coding (18 digits). Personal identity self-coding (18th digit) is an educational identity number given to the educated individual by the Ministry of Education according to these rules when the educated individual does not have a citizenship number (the second generation) or the original citizenship number is not available. Personal identity self-coding (18 bits) is a feature combination code, which consists of a 17-bit digital ontology code and a check code. The order from left to right is: six-digit address code, eight-digit date of birth code, three-digit serial code and one-digit check code.

Temporary student number: the national temporary student number coding rule is L+ the number generated according to the ID number coding rule (6-digit school district code +8-digit birth date +4-digit random code).

Official student number: with ID number: G+ ID number. No ID number: J+ ID number generation rules.
