Tool Introduction

The “Administrative Sub-region Division Query” tool aims to help users quickly obtain detailed division information of all sub-regions under a specified parent administrative region ID. Whether it's provincial, city, district/county, township, or village committee, you can query its direct subordinate administrative units by entering the corresponding parent ID. The query results will be presented in a clear table format, including rich geographical and administrative information such as area ID, name, level, longitude, latitude, zip code, area code, and pinyin, facilitating your data organization and analysis.

Administrative Division Hierarchy System

China's administrative division system is a multi-level structure, and the “level” field of this tool clarifies the administrative level of each region:

• 1: Provincial - Includes provinces, autonomous regions, municipalities directly under the central government, and special administrative regions.
• 2: City-level - Includes prefecture-level cities, autonomous prefectures, leagues, etc.
• 3: District/County-level - Includes municipal districts, counties, autonomous counties, banners, autonomous banners, forest areas, special zones, etc.
• 4: Township-level - Includes townships, ethnic townships, towns, sub-districts, etc.
• 5: Village Committee-level - Includes villagers' committees, residents' committees, and other grassroots units.

Understanding these levels helps you more accurately locate and query the required administrative regions.

How to Use

1. In the “Parent ID” input box on the tool page, enter the administrative region ID for which you want to query its subordinate sub-regions. For example, if you want to query all districts and counties in Shanghai, you need to enter Shanghai's administrative ID (e.g., “310000”).
2. Ensure the entered ID is valid.
3. Click the query button, and the tool will return all matching administrative sub-region information based on the parent ID you provided.
4. Results will be displayed in a paginated table format. You can view 20 data entries per page and browse all results using the pagination controls at the bottom.

Frequently Asked Questions

• Q: How to get the correct parent ID?
• A: You usually need to first query the detailed information of a certain region (e.g., using an area name query tool) to obtain its ID, which can then be used as the “Parent ID” for querying subordinate regions with this tool. For example, to query the districts and counties of Beijing, you need to first obtain Beijing's ID.
• Q: What does “--” in the query results mean?
• A: This means that there is no corresponding data or the data is missing for this field in the current query results. For example, a village committee-level region may not have independent area code information, in which case “--” will be displayed.
• Q: Which fields are supported in the output results?
• A: The output results support detailed fields such as Provincial Code, Area Name Abbreviation, Longitude, Latitude, City Code, Area Code, Pinyin Initial, Township ID, Area ID, Full Pinyin of Area Name, Parent Code, Village Committee ID, Area Level, Area Name, Simple Pinyin, Zip Code, District/County Code, and Full Name.
• Q: Why are the query results empty?
• A: Possible reasons are that the “Parent ID” you entered is incorrect, does not exist, or the administrative region corresponding to that ID currently has no subordinate sub-region divisions. Please check if the entered ID is correct.

Notes

• The “Parent ID” is a required parameter. Please make sure to enter the correct administrative region code, otherwise no results will be found.
• This tool supports paginated display, with 20 data entries shown per page by default. If there are many query results, please pay attention to flipping pages to view them.
• Please distinguish between the “id” and “parentId” fields. “id” is the unique identifier of the current region, while “parentId” is the ID of its parent region.
• The definition of the “level” field is crucial for understanding the hierarchical relationship of administrative regions. Please pay attention to this field according to your needs.
