The reasons are as follows

First, the student registration number is the only number registered by the student and filed by the school and the Education Bureau. The student registration number consists of 16 digits. The student registration number is generated according to the student's ID number. A student has a number, which will remain unchanged for life in principle throughout the student's study career. There are three types of student registration numbers: official student registration numbers prefixed with "G", temporary student registration numbers prefixed with "L" and student registration numbers prefixed with "J". The more common ones are the official student number prefixed with "G" and the temporary student number prefixed with "L".

Second, the student number is the student number. The school prints this number on the campus card, so that the campus card can also use this number to show your identity. Secondly, this number can be said to be a very important number in college life. The school assigns a number to each student to facilitate student management. Generally, everyone's student number will not be repeated, and the number will generally contain information such as year and class.
