Guinea-Bissau is divided into 9 regions, which constitute the first level of administrative division in the country's two-tier system. These regions serve as the primary units for implementing national policies and delivering government services to local populations. Regional administrations are responsible for coordinating development projects, maintaining public infrastructure, and overseeing healthcare and education facilities within their territories. They act as intermediaries between the central government in Bissau and the smaller administrative units below them, facilitating communication and resource allocation. Each region is governed by appointed officials who manage local affairs while ensuring compliance with national directives and regulations.
