This number, to some extent, has a function similar to that of the social security number in the United States, and each citizen has a unique number that remains unchanged for their entire lifetime. The ID card is used for residential registration, army enrollment registration, registration of marriage/divorce, going abroad, taking part in national exams, and other social or civil matters.įrom October 1, 1999, the PRC State Council approved the establishment of a citizen identification number system, and currently consists of an 18-digit code.

In 15 digit IDs, III is an identification number created through certain mathematical methods (the last digit might be an English letter, such as X). The sum modulus 11 is used as an index into the ordered set, with the first index being zero. To calculate the checksum, each digit in order is multiplied by a weight in the ordered set and summed together.

The final character, C, is a checksum value over the first 17 digits. The sequential code is odd for males and even for females. RRRRRR is a standard code for the administrative division where the holder is born (county or a district of a city), YYYYMMDD is the birth date of the holder, and SSS is a sequential code for distinguishing people with identical birthdates and birthplaces. The ID number has 18 digits and is in the format RRRRRRYYYYMMDDSSSC, which is the sole and exclusive identification code for the holder (an old ID card only has 15 digits in the format RRRRRRYYMMDDIII). In the PRC, an ID card is mandatory for all citizens who are over 16 years old. What is Chinese Id Card Number or Resident Identity Card?
