Udakishunganj is a community development block and subdivision headquarters town in Madhepura district, Bihar, situated in the alluvial plains of the Kosi river basin in northeastern Bihar. The Kosi river — often called the "Sorrow of Bihar" for its history of dramatic course changes and flooding — has shaped much of the region's settlement patterns, agriculture, and infrastructure planning for generations.
Administrative position
Udakishunganj serves a dual administrative role: it is both a community development block in its own right and the headquarters of Udakishunganj subdivision, which groups together several neighbouring blocks under a Sub-Divisional Officer based in the town. The block itself is organised into gram panchayats covering roughly 44 villages — see our full panchayat and village list.
Population
Published census figures put Udakishunganj block's population at approximately 136,937 as of the 2001 census; more recent block-level figures from the 2011 census (or later) were not available from the sources consulted for this page. For current, authoritative population data, the District Census Handbook for Madhepura, published by the Census of India / Directorate of Census Operations, Bihar, is the definitive source.
Why udakishunganj.com exists
Most information about small Bihar blocks like Udakishunganj is scattered across district administration pages, Wikipedia stubs, and generic listing sites — making it hard to find practical, block-specific answers to everyday questions like "where do I get my ration card e-KYC done" or "which panchayats make up this block." This site exists to bring that hyperlocal, practical information into one place, always pointing back to the official government source for anything that needs verification.
The bottom line
Udakishunganj's identity is shaped by its place in the Kosi basin and its dual role as block and subdivision headquarters — practical, everyday context that's easy to lose in generic statewide coverage of Bihar.
