Область применения

This standard applies to the assignment of a unique, unchanging legal number to citizens of the People's Republic of China. It defines the coding object, structure, and representation format for the citizen identification number. This standard is mandatory for all systems processing Chinese citizen ID data. It replaces the previous GB 11643-1989 standard.

Технические требования

The standard specifies an 18-digit feature combination code consisting of a 17-digit master number and a 1-digit check number. The structure is divided into four segments: a 6-digit address code representing the administrative division, an 8-digit birth date code formatted as YYYYMMDD, a 3-digit sequence code where odd numbers are assigned to males and even numbers to females, and a 1-digit check code. System developers must ensure the full 18-digit structure is implemented without spaces. The address code must comply with GB/T 2260, and the birth date code must comply with GB/T 7408.

Методы испытаний

The standard outlines the validation method using the ISO 7064:1983, MOD 11-2 check code system. It provides a specific mathematical formula and a table of weighting factors to calculate the check digit. Developers must implement this exact algorithm to validate the accuracy of ID number entry or transcription. If the calculated check digit is 10, it is represented by the Roman numeral X.
