Recent projects used to judge the legality of the id card original thinking of regular online a lot of, just copy and paste the one, who wanted to meet a id number with X-ray test, the test says change X to Numbers, is not the correct id number, you write wrong, id long ago heard that regular can only judge the format is correct, and calculated to id for the correctness of algorithm.

Look at the following id common sense, then look at the code, your logic is clear.
Our country's id number is divided into 15 and 18.Id is a national identity number, the number is not random. Resident identity card number, according to the showing of the People's Republic of China national standard GB 11643-11643] in the regulations on citizen id Numbers, citizenship combined code number is characteristics, by 17 digit code of ontology and a number of check code.The order from left to right in turn for: six figures address code, eight digit birth date code, the three digital sequence code and a digital check code.Resident identity card is the national legal proof of valid certificates of the identity of the individual citizens.
- The structure of the number
Citizen identity number is characteristics of combination code, the seventeen of digital ontology yards and a check code.The order from left to right in turn for: six figures address code, eight digit birth date code, the three digital sequence code and a digital check code.
2．Address code
Encoding the object the permanent residence county (city, flag, area) of administrative division code, shall be governed by the provisions of the GB/T2260.
3．Birth date code
said coding object birth year, month, day, according to the provisions of the GB/T7408, year, month, day without separators between code.
4．The order code
said at the same address code identified areas within the scope of the people born in the same year, in the same month, on the same day of serial number, sequence code odd number assigned to the male, the even assigned to women.
5．Check code
according to the previous 17 digit word, according to ISO7064:1983 MOD11-2 check code calculated check code.
- Address code
In north China： The Beijing municipal|110000，tianjin|120000，In hebei province|130000，Shanxi Province|140000，The Inner Mongolia autonomous region|150000，
In the northeast： Liaoning province|210000，Jilin province|220000，Heilongjiang province|230000，
East China area： Shanghai|310000，Jiangsu province|320000，Zhejiang province|330000，In anhui province|340000，Fujian province|350000，Jiangxi province|360000，In shandong province|370000，
In central China： Henan province|410000，Hubei province|420000，Hunan province|430000
In south China： Guangdong province|440000，The guangxi zhuang autonomous region|450000，Hainan province|460000，
In the southwest： chongqing|500000，Sichuan province|510000，The guizhou province|520000，In yunnan province|530000，The Tibet autonomous region|540000，
The northwest region： Shanxi province|610000，Gansu province|620000，Qinghai province|630000，The ningxia hui autonomous region|640000，The xinjiang uygur autonomous region|650000，
Special area：The Taiwan region(886)|710000，The Hong Kong special administrative region（852)|810000，The Macao special administrative region（853)|820000
Said the first, two provinces (autonomous regions and municipalities directly under the central government, special administrative region).
The third and fourth said city (prefecture, autonomous prefectures and African union (au) and the national municipality directly under the central government's municipal districts and counties of summary code).Among them, 01-20: pp.49-60 70 provinces municipalities directly under the central government;21 to 50 said region (autonomous prefectures and au).
Fifth, said the county (municipal, county-level city, flag).01-18 municipal district or region (autonomous prefectures and au) governs county;21-80 counties (banners);81-99 indicates directly under province county.
- Birthday period code
id number 7 to 14 encoding the object birth year, month, day, one year with four digits, said no separators between year, month, day.For example, May 11, 1981 in 19810511.
- The order code
id number to fifteenth to address identified areas within the scope of seventeen, born of the same year, month, the staff of serial number.17 odd among men, even among women
- Check code
as a private check code, it is calculated by number unit according to the unified formula, if someone's tail number is 0-9, X will not appear, but if the tail is 10, then to use X to replace, because if made tail number 10, then this person id card becomes a 19, and violated the national standard, the number 19 and China's computer application system does not recognize identification number 19.Ⅹ is Roman numeral 10, with 10 X instead of, can guarantee citizen id card is in line with national standards.
- The calculation method of id check code
1、 will be in front of the id card number 17 digit number multiplied by the coefficient of different respectively.From the first to 17 coefficient respectively: 7-9-10-5-8-4-5-8-4-3-7-9-7-9-10-4-2.
2、 the coefficient of 17 Numbers and the result of the multiplication addition.
3、 in and out, and divided by 11, the remainder is how much?
4、 the remainder may have only 0-1-2-3-1-2-3 - the 7-8-9-10 this 11 Numbers.Its respectively corresponding to the last id number is 1-0 - X - 9-8-7-9-8-7-3-2.(that is, the remainder 0 corresponds to 1, the remainder corresponding to 0, 1 remainder 2 corresponding X...)
5、Through that if the remainder is above 3, in the id card on the 18th of digital is 9.If the corresponding number is 2, the last of the id card number is the Roman numerals x.
