Postcode Lookup

Data from the chinese-postcode project (ISC): 2957 rows across 31 province-level units and 344 cities, down to district level. Two limitations: each district contributes a single representative postcode (Chaoyang in Beijing has both 100020 and 100102; this table lists 100102), and the district list is a snapshot that still contains a few abolished districts (Chongwen, merged into Dongcheng in 2010). Postcodes rarely change, but names may be stale — for anything official, check with China Post.
