About this dataset
Postal Codes Dataset for Vietnam (VN)
This dataset contains Vietnamese postal codes across every province on the 2025 administrative structure (Decree 19/2025), at ward-level granularity.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
Administrative names and codes (province/ward) are sourced from provinces.open-api.vn v2, official General Statistics Office data under Decree 19/2025. Postal codes are sourced from gatewayexpress.vn, a third-party aggregator reproducing the official VNPost/MIC ward-level list, cross-checked against an independent aggregator (mabuudien.net).
Licensing status — read before commercial use. This dataset's licence status is unresolved for the postal layer: neither aggregator is the rightsholder for the underlying VNPost/MIC codes, and no explicit redistribution licence has been confirmed from either. See ATTRIBUTION.txt for the full disclosure. Contact datahub@datopian.com before relying on this dataset under a licence that requires a confirmed redistribution grant.
Usage
The dataset files are available in CSV format and can be accessed and downloaded using the links provided in datapackage.yaml.
postal_code and admin_code1 must be read as text (dtype=str) — a naive pd.read_csv() can otherwise mis-handle leading zeros.
