What is the Dag number?

It's West Bengal's parcel identifier — the unique number assigned to a plot of land. Also called 'plot number' or 'survey number' locally. It appears in Khatian and property documents.

What's the difference between RS and LR?

RS (Revenue Survey) and LR (Land Records) are two historical survey systems used in West Bengal. Older documents may reference RS; newer ones may use LR. Banglarbhumi integrates both systems.

How do I know if my document uses RS or LR?

Check the date on your property deed or document. Older documents tend to use RS Dag numbers. Search Banglarbhumi to cross-reference and find equivalent LR numbers.

Are Banglarbhumi records free?

Yes. All Khatian, Dag-based documents, and land records are free from Banglarbhumi (banglarbhumi.wb.gov.in). Do not pay agents for extracts.

Survey Numbers in West Bengal

Q: What is the Khatian?

It's the ownership register listing all land held by one person in a village, identified by Dag number. Shows area, boundaries, and ownership.

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.
