About this dataset
Postal Codes Dataset for Mongolia (MN)
This dataset lists the five-digit unified postal codes of Mongolia with place names and
administrative divisions: the aimags and Ulaanbaatar, with the
city districts of Ulaanbaatar in admin_name2. It carries no coordinates.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
- Postal codes and place names: © Communications Regulatory Commission of Mongolia, "Unified Postal Code" (Шуудангийн нэгдсэн код), published on the national open-data portal under Minister's Order A/24 (2024-09-30). The portal does not state a machine-readable reuse licence; the file is treated as government open data on the basis of its formal publication under that order.
Changes made to the source data: admin_code1 derived as ISO 3166-2:MN by a name-based crosswalk
(not the source's own area codes); each area header row of the source added as a data row for the
area's base code; all Ulaanbaatar districts grouped under Ulaanbaatar (MN-1).
Not endorsed by, or affiliated with, the Communications Regulatory Commission of Mongolia.
Known limitations
- The source states no machine-readable reuse licence (see above).
- "Сүхбаатар" is both a district of Ulaanbaatar and a separate aimag (MN-051); they are told apart by the source's area header (district vs aimag).
Usage
The dataset files are available in CSV format and can be accessed and downloaded using
the links provided in datapackage.yaml.
