Estonia Administrative Divisions

Estonia is divided into 15 counties (Maakonnad), which form the top-level administrative units. These are subdivided into 24 urban municipalities (Linnad) and 55 rural municipalities (Vallad). The smallest administrative level consists of 8 administrative districts (Linnaosad). Major counties include Harju, Hiiu, and Ida-Viru.

Estonia has 3 administrative levels. Level 1: 15 counties (Maakonnad). Level 2: 24 urban municipalities (Linnad) and 55 rural municipalities (Vallad). Level 3: 8 administrative districts (Linnaosad).

Estonia operates on a 2‑level system starting with 15 counties, followed by rural municipalities, 4 urban municipalities as the smallest administrative units.

In Estonia, urban municipalities and rural municipalities both sit at administrative level 2 but serve different functions. Urban municipalities (linnad) — there are 24 — are typically a larger city or urban area that govern itself independently. Rural municipalities (vallad) — there are 55 — group multiple smaller municipalities under a shared administration.

Estonian administrative divisions have specific local names at each level. In Estonian, counties are called Maakonnad; urban municipalities are called Linnad; rural municipalities are called Vallad; administrative districts are called Linnaosad. These local-language terms appear in official documents, legal records, and government databases, so matching them correctly is important for data integration and compliance.

Administrative boundaries in Estonia change as governments reorganize regions, merge municipalities, or create new administrative units to reflect population shifts and political decisions. Changes most commonly affect the administrative districts level, where Estonia currently has 8 units. Businesses that rely on Estonian administrative data should use a regularly updated reference dataset to avoid mismatches in geocoding, tax jurisdiction mapping, and compliance reporting.
