Subordinate Administrative Region Lookup: Core Features and Principles
When you need to retrieve all child units under a specific administrative region (such as a province or city), simply enter the region's unique ID. Based on China's standard administrative division coding system, this tool returns complete data in real-time across 5 administrative levels (Province → City → District/County → Township → Village). The output includes 12 key data points such as the administrative region ID, name, level, and latitude/longitude coordinates.
Why Choose Our Subordinate Administrative Region Lookup?
- Comprehensive Level Coverage: Supports queries across levels 1 to 5, including differentiated processing for special administrative regions (e.g., direct-administered municipalities, autonomous prefectures).
- Multiple Data Dimensions: In addition to basic names and IDs, it provides practical fields like postal codes, area codes, and Pinyin.
- Standardized Results: Strictly follows the GB/T 2260 administrative division codes to ensure data authority and accuracy.
How to Use
- Obtain the 6-digit ID of the target administrative region (e.g., 110000 for Beijing).
- Paste or type the ID into the input box.
- Click the query button to get the results in JSON format.
Frequently Asked Questions (FAQ)
Q: How can I verify if an administrative region ID is correct?
Simply enter the 6-digit ID to query. If it returns an empty result, the ID is incorrect. Examples of valid IDs: Shanghai is 310000, Guangzhou is 440100.
Q: Why is postal code data missing for village-level administrative units?
In China, village-level units typically share the postal code of their parent township. The tool will display the parent postal code. For example, a village committee in Chaoyang District, Beijing, will show 101499 (the postal code for Chaoyang District).
Important Notes
Please ensure the 6-digit ID you enter corresponds to a provincial or municipal unit (e.g., to query at the district/county level, use the parent city's ID). The latitude and longitude coordinates represent the administrative center, not precise boundary data. Special coding rules apply to Hong Kong, Macau, and Taiwan.
Technical Notes & Best Practices
We recommend developers use the latitude and longitude data in conjunction with Geohash. Typical use case: If a logistics system needs the coordinates of all districts and counties in Zhejiang Province, first query the ID 330000 to get the 11 prefecture-level cities, then query each city for its subordinate districts and counties to ultimately obtain the geofencing data for all 90 district/county units.
