Portugal Administrative Divisions

Portugal is divided into 18 districts (Distritos) and 2 autonomous regions (Regiões Autónomas), which form the top-level administrative units. These are subdivided into 308 municipalities (Concelhos). The smallest administrative level consists of 3,092 parishes (Freguesias). Major districts include Aveiro, Azores, and Beja.

Portugal has 3 administrative levels. Level 1: 18 districts (Distritos) and 2 autonomous regions (Regiões Autónomas). Level 2: 308 municipalities (Concelhos). Level 3: 3,092 parishes (Freguesias).

Portugal operates on a 3‑level system starting with 20 districts, then municipalities, and parishes as the smallest administrative units.

In Portugal, districts and autonomous regions both sit at administrative level 1 but serve different functions. Districts (distritos) — there are 18 — typically group multiple smaller municipalities under a shared administration. Autonomous regions (regiões autónomas) — there are 2 — are a larger city or urban area that handle its own administration independently.

Portuguese administrative divisions have specific local names at each level. In Portuguese, districts are called Distritos; autonomous regions are called Regiões Autónomas; municipalities are called Concelhos; parishes are called Freguesias. 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 Portugal change as governments reorganize regions, merge municipalities, or create new administrative units to reflect population shifts and political decisions. Changes most commonly affect the parishes level, where Portugal currently has 3,092 units. Businesses that rely on Portuguese administrative data should use a regularly updated reference dataset to avoid mismatches in geocoding, tax jurisdiction mapping, and compliance reporting.
