Overview
West Bengal uses Dag numbers (also called plot numbers or survey numbers) to identify land parcels. The Khatian is the ownership register. RS (Revenue Survey) and LR (Land Records) are the two historical survey systems that may appear in your documents — Banglarbhumi integrates both. The Banglarbhumi portal lets you search and download records free.
