About this dataset
Postal Codes Dataset for Singapore (SG)
This dataset lists Singapore postal codes, one row per postal code, with the building or road name, CDC district, URA planning area and subzone, and building-level coordinates.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
- Postal codes, building and road names, and building-level coordinates: © OneMap, Singapore Land Authority (address dump), Singapore Open Data Licence v1.0.

The Singapore Open Data Licence permits commercial and non-commercial use, copying, distribution, transmission, and adaptation, provided attribution accompanies any redistribution.

subzone polygon (codes with no such record, non-numeric codes and records without a usable coordinate dropped);
place_name set to the building name, or the road name when there is no building; planning area and subzone
names title-cased; CDC district derived from the subzone's URA region; coordinates rounded to 7 decimal places
and blanked when outside Singapore.
