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.
Most recent COD-AB review conclusion: The COD-AB does not require any update.
An edge-matched (COD-EM) dataset is available
COD-EM HDX link:

OCHA country status: Operational (country office).
Most recent COD-AB review date: January 2025.
Deepest administrative level: ADM4.

Live featureserver:

Deepest administrative level with complete coverage: ADM3.
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. 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.
Note: ADM0 is not affected by the September/October 2024 administrative feature renaming exercise.
Typical feature type: oblast (region) with three exceptions.
P-code format: UAnn.
COD-PS compatibility: ADM0, ADM1, ADM2.
OCHA region: Europe.
Feature count: 27.
The ADM1 layer can be linked by P-CODE to the ADM1 Population statistics.
Note: Kyiv (city) [UA80] and Sevastopol [UA85] are each a 'city with special status' rather than an 'oblast'.
Note: Crimea [UA01] is an 'autonomous republic' rather than an 'oblast'.
Note: However, Ukraine Population Statistics are only available on special request.
ADMINISTRATIVE LEVEL 4 metadata:
Typical feature type: ADM4 features may be of 'city', 'settlement', or 'village' type. However, all 'village' features are currently categorized in the 'ADM4_TYPE' as a 'settlement'. This is expected to be resolved in 2026.
P-code format: UAnnnnnnnnnn.
Feature count: 29707.
COD-PS compatibility: no ADM4 population statistics are available.

Note: 329 ADM4 features were affected by the September/October 2024 administrative feature renaming excercise.

Note: The COD-AB ADM4 boundary attributes for this COD-AB have not been adjusted.
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.
