Which city and county does 0728 on the ID number represent? The first two don't know.

The first two digits of the ID number represent the information of provinces and cities, and 0728 in different provinces and cities represents different cities and counties. So if you don't know the first two digits of your ID card, you can't be sure which city and county it belongs to.

The digital coding rules of the address code in the resident ID card number are as follows:

The first and second digits represent provinces (autonomous regions, municipalities directly under the Central Government and special administrative regions).

The third and fourth representative cities (summary codes of prefecture-level cities, autonomous prefectures, leagues, municipalities directly under the Central Government, municipal districts and counties). Where 0 1-20 and 5 1-70 represent provinces and municipalities directly under the central government; 2 1-50 indicates regions (autonomous prefectures and leagues).

The fifth and sixth representatives represent counties (municipal districts, county-level cities and banners). 0 1- 18 refers to the county-level cities under the jurisdiction of municipal districts or regions (autonomous prefectures and leagues); 2 1-80 stands for county (flag); 8 1-99 stands for county-level cities directly under the provincial government.
