Digital encoding rules address code of mainland China resident identity card numbers are as follows:
first, two represent the province (autonomous regions, municipalities and special administrative regions).
Third, four bits represent the (yard summary prefecture-level cities, autonomous prefectures and regions, and municipalities in their district and Union County) city. Among them, 01-20,51-70 represents the prefecture-level cities; 21-50 represents areas (prefectures and leagues).
Fifth, six represent the county (district, county-level cities, flag). 01-18 represents the prefecture-level cities, autonomous prefectures, regional, county-level city under the jurisdiction of the AU; 21-80 represents a county (banner); 81-99 represents the province directly under the county-level administrative units.
Birth date code
1. (ID number seventh to fourteenth) an encoding target birth year, month, day, year in which is represented by four digits without separators between year, month, day. For example: May 11, 1981, says with 19,810,511.
Order code
1. (ID number fifteenth to seventeen) within the region identified by the address code of the same year, month, people born scheduled sequence number. Which seventeenth odd given to men, women give an even number.
Check code
1. As the tail number of the checksum is calculated in accordance with the unified formula Prepared by the number, if someone's tail number is 0-9, X will not occur, but if the tail number is 10, so you have to use X instead, because if done with tail number 10, then the person's identity becomes 19, and 19 numbers in violation of national standards, and China's computer application system does not recognize the 19 ID number. Ⅹ is the Roman numeral 10, to replace the X-10, it can guarantee citizens' identity cards in line with national standards.
