In 1 May 2014 correspondence with the Research Directorate, an official at the Embassy of Canada in Beijing provided the following information on the use of the letter "X" as the last digit of the identification number on resident identity cards [RICs] in China:
The State Council of PRC [the People's Republic of China] issued a decision on citizen identification number system effective Oct. 1, 1999. Citizen identification number is made in accordance with GB11643-1999 national standard.
It consisted of 18 digits:
first 6 are Address code (Administrative area code),
the 7th-14th digits are Birth date code (YYYY/MM/DD),
the 15th-17th digits are Sequence code (for people with same DOB and address code, odd number for Male, and even number for Female),
last digit is Check code (from 1-10). Check formula is
18
Σ (ai x Wi) ≡ 1(mod 11)...(1)
i=1
If the character value is 10, "X" will be used instead of 10.
