About Subdivisions in Bihar

Bihar has 536 subdivisions (also known as tehsils, mandals, or subdivisions in other parts of India) spread across 39 districts. These administrative divisions form the crucial sub-district tier in India's multi-level governance structure, sitting between districts at the top and development blocks/villages at the grassroots level.

Each subdivision in Bihar is headed by a Tahsildar (also called Subdivision Officer or Tehsildar), a key revenue officer who holds significant administrative and quasi-judicial powers within the jurisdiction. The Tahsildar is responsible for land revenue collection, maintaining land records and property documentation, issuing essential government certificates, conducting local elections, implementing welfare schemes, and serving as a first-level magistrate for minor disputes. Citizens frequently visit subdivision offices for income certificates, caste certificates, residence certificates, property mutations, and other critical documentation needs.

Understanding the subdivision structure of Bihar is essential for accessing government services, finding local administrative offices, and understanding the regional administrative geography.
