The actual boundaries were most recently adjusted in: January 2025. Boundary information source: State Scientific Production Enterprise “Kartographia”. Contributor: OCHA Field Information Services Section (FISS). COD-AB quality level: cod-enhanced (geometry and attributes verified and standardized) and live services available. https://codgis.itos.uga.edu/arcgis/rest/services/COD_External/UKR_pcode/FeatureServer[feature server](https://codgis.itos.uga.edu/arcgis/rest/services/COD_External/UKR_pcode/FeatureServer). Most recent COD-AB review conclusion: The COD-AB does not require any update. OCHA country status: Operational (country office). An edge-matched (COD-EM) dataset is available Most recent COD-AB review date: January 2025. Deepest administrative level: ADM4. COD-PS HDX URL: https://data.humdata.org/dataset/cod-ps-ukr. Deepest administrative level with complete coverage: ADM3. COD-EM HDX link: https://data.humdata.org/dataset/cod-em-ukr. Administrative level required by humanitarian community: ADM2. Note: The Ukrainian government has not fully implemented its new administrative structure reforms in the Autonomous Republic of Crimea [UA01] and Sevastopol [UA85]. Consequently, 31 ADM4 features within the Sevastopol ADM3 polygon retain P-codes that do not correctly conform to [UA85]. This will be rectified in a COD-AB update once the government has regained control of the Crimean Peninsula. Note: Some administrative feature names were adjusted in a September/October 2024 administratrive feature renaming exercise. See reference table at https://data.humdata.org/dataset/cod-ab-ukr. Note: The Ukraine COD-AB was most recently adjusted in early 2024 - affecting administrative level 3 (hromadas) only. Note: The population statistics common operational dataset (COD-PS-UKR) is only available via special request. See [Ukraine - Subnational Population Statistics](https://data.humdata.org/dataset/cod-ps-ukr). Users should use the 'Request Data' button. Note: Limitations of the Ukrainian-to-Russian transliteration method mean that more than one Ukrainian name may be represented by a single Russian feature name. Note: Feature name attribute fields in this dataset incorrectly use 'UA' to represent the Ukrainian language. The correct language code is 'UK'. This will be resolved in 2026.
