Usage Notes

China's administrative divisions are organized into several types:
- 4 Municipalities (直辖市) - directly under central government control
- 22 Provinces (省) - standard provincial administrative regions
- 5 Autonomous Regions (自治区) - regions with large ethnic minority populations
- 2 Special Administrative Regions (特别行政区) - Hong Kong and Macau
All codes follow the format 'CN-' followed by two letters
Municipalities have provincial-level status in China's administrative hierarchy
The autonomous regions have the same political status as provinces but with more legislative rights
Special Administrative Regions (Hong Kong and Macau) operate under the "One Country, Two Systems" principle

Special Cases

The four municipalities (Beijing, Shanghai, Tianjin, and Chongqing) are directly administered by the central government
Hong Kong (CN-HK) and Macau (CN-MO) maintain separate political and economic systems
Taiwan (CN-TW) is listed for completeness but its political status is subject to international dispute

Data Usage

When specifying locations in China in your API requests, please use these exact codes
For addresses in Special Administrative Regions, use their specific codes (CN-HK or CN-MO)
Consider regional differences in address formats, particularly for Special Administrative Regions

Note: Taiwan's inclusion in this list is for technical completeness and follows ISO standards. Its political status is subject to different interpretations internationally.
