China ID Card - An Introduction

by Matt Slater October 31, 2018

China ID Card

If you have done business with a Chinese company there is a good chance that their staff have provided you with a scan or photo of their China ID Card.

This ID Card, also known as the Resident Identity Card, is compulsory for all Chinese citizens and contains much information about the holder.

Each China ID Card has a unique 18-digit Citizen Identity Number and knowing this number alone can tell you the holder's date of birth, place of birth and gender.

What is a China ID Card?

The official name of the China ID Card is displayed on the front of each card in large Chinese characters:

中华人民共和国 (People's Republic of China)
居民身份证 (Resident Identity Card)

    Having an ID Card is compulsory for all citizens of Mainland China and most Chinese carry their card on their person most of the time.

    The China ID Card is the size of a regular credit card, is of a standard design and contains important information on both sides.

    Here is a sample of the front of a China ID Card:

    Here is the back of the China ID Card, which usually contains a color photo of the individual on the right-hand side:

    What Information is Contained in a China ID Card?

    The following details are each displayed on the China ID Card:

    Front of China ID Card

    • Issuing Authority (签发机关) - this gives the location of the public security bureau which issued the card
    • Period of Validity (有效期限) - the period given depends on the age of the individual, citizens over 46 years are given a "long-term" card with no expiry date

    Back of China ID Card

    • Name (姓名) - in China the surname is written first & the vast majority of Chinese citizens have a single character surname
    • Gender (性别) - must be male (男) or female (女)
    • Ethnicity (民族) - China recognizes 56 different ethnic groups, with Han (汉) being by far the most common at over 90%
    • Date of Birth (出生) - written in form Year (年) Month (月) Day (日)
    • Address (住址) - although many Chinese citizens move away from home for work, this address usually refers to their "hometown address"
    • Citizen Identity Number (公民身份号码) - read more about this below

    How does the China ID Card Citizen Identity Number work?

    All Chinese citizens are issued with a unique 18-digit Citizen Identity Number which stays with them for their whole life.

    This national identification code follows a set pattern from which some basic information can be determined, such as their place and date of birth.

    Here is a breakdown of how the number is created:

    1 1 0 1 0 1 Y Y Y Y M M D D 1 2 3 X
    Address Code Date of Birth Code Order Code Checksum

    Address Code

    The address code pinpoints to a specific administrative division (in most cases a district or county) where a Chinese citizen was born.

    The first 2 digits of the Citizen Identity Number represents the province, the next 2 digits the city and the final 2 digits the district or county.

    There are nearly 3000 different address codes so it wouldn't be practical to list them all here, but here are the province codes (i.e. the first 2 digits of the Citizen Identity Number) for each region of China:


    Even if a Chinese citizen changes their hukou (household registration) to a different province, their citizen identity number doesn't change.

    An interesting example of this is that older citizens of Chongqing have ID numbers beginning with 51 rather than 50, as Chongqing was carved out of Sichuan in 1997 to create a new province.

    Date of Birth Code

    These 8 digits are simply the individual's date of birth in the format Year, Month, Day.

    Order Code

    Interestingly with this 3-digit number, odd number are issued to males and even numbers to females. No other discernible information is revealed.

    Checksum

    This digit is simply a check that the Citizen Identity Number is valid.

    This website claims to generate valid China ID Card numbers and can also be used to identify all of the address codes.
