Encoding Rules for Second Generation ID Numbers in Mainland China 

The second-generation citizen ID card in mainland China has a total of 18 digits. According to the regulations on the citizen ID number in the National Standard of the People's Republic of China GB 11643-1999: the citizen ID number is a feature combination code, which consists of a 17-digit body code and a 1-digit school code composition.

From left to right are:

• 6-digit address code: indicates the code of the province (municipality, autonomous region), city and county where it is located;
• 8-digit birth date code: Indicates the citizen's birth year (4 digits), month (2 digits), and day (2 digits);
• 3-digit sequence code: the sequence code representing the same place of birth, where odd numbers represent males and even numbers represent females;
• 1-digit check code: Check code generated from the preceding 17 digits (calculated according to ISO 7064:1983.MOD 11-2).

The following figure clearly shows the coding rules of the second generation ID number in mainland China ▼

The following will introduce the coding rules of the second-generation citizen ID card in detail, according to the resident's place of birth (address code), date of birth, sequence code and check code.

Positions 1-6: Location

The 1st to 6th digits are the address code, indicating the administrative division code of the county (city, district) where the person's permanent residence is located.

Among them, the first two represent specific provinces (municipalities directly under the Central Government, autonomous regions, special administrative regions), and the codes are as follows:

• 11-15: Beijing-Tianjin-Hebei Jinmeng
• 21-23: Liao Ji Hei
• 31-37: Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi and Shandong
• 41-46: Henan, Hubei, Hunan, Guangdong, Guiqiong
• 50-54: Yuchuan Guiyun Tibet
• 61-65: Shaanxi-Gansu Qingning New

The 3rd and 4th digits are the city code, and the 5th and 6th digits are the district and county codes.The location on the ID number is represented by this 6-digit code.

Nos. 7-14: Date of birth

• The 7th to 14th digits are the date of birth code, indicating the citizen's birth year, month, and day, a total of 8 digits.Among them, the year is 4 digits, and the month and day are 2 digits (less than two digits are preceded by 0).
• Such as: 19970430, which means born on April 1997, 4.

Bits 15-17: Sequence code

• The 15th to 17th bits are the sequence code.Sequence code refers to the sequence number assigned to people born in the same year, month, and day in the same region, with a total of 3 digits.
• Among them, odd numbers are assigned to men and even numbers are assigned to women.

Bit 18: Check Digit

The last digit of the ID number is the check digit.The check digit is based on the first 17 digits, according to the specified calculation rules.

The check code is calculated as follows:

1. For the first 17 digits, each digit is multiplied by a corresponding factor, and these products are summed to obtain the value A.The factor used in this step is a fixed sequence of 17 digits: 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4 ,2.That is to say, for the 17 numbers obtained earlier, the first number is multiplied by 1; the second number is multiplied by 7; the third number is multiplied by 2 ... and so on.For example, the first 9 digits of an ID number are 43050220040304292, then according to the algorithm requirements, the calculation formula is:A = 4 * 7 + 3 * 9 + 0 * 10 + 5 * 5 + ... + 2 * 2
2. Divide the sum from step 1 by 11 and get the remainder.For example, after multiplying the 17-digit ID number and the factor in the above example, the calculated sum is 207, and then calculate 207 / 11 The remainder of , yields 9.
3. According to the remainder obtained in step 2, compare the check code table below to obtain the corresponding check code (where X represents 10 in Roman numerals).

• According to the above comparison table, when the remainder is 9, the corresponding check code is 3, so the resident's citizenship number should be430502200403042923.
