China administrative division codes, 1981–2025

This dataset covers the province, prefecture and county levels in its declared 1981–2025 source range. It is not a current 2026 register, a street or village directory, or a postcode database.

The ZIP includes history.csv (6,824 rows), snapshot-2025.csv (3,212 rows), successors.csv, the unchanged source JSON, field definitions and license notices. CSV files use UTF-8 and headers in the selected language. Import code columns as text. The PDF explains the fields and includes the same worked boundary check; the full data is in the ZIP.
