RS and LR Plot Information on Banglarbhumi (Hal Dag vs Sabek Dag Explained)
RS and LR confusion is one of the single biggest reasons people get stuck during property verification in West Bengal. A seller shows you an old RS dag number, the current portal record shows an LR number, and suddenly nobody is sure if they’re even talking about the same piece of land.
This guide explains what RS and LR actually mean, how the Hal Dag to Sabek Dag mapping tool works on Banglarbhumi, and how I personally use it to confirm that an old reference and a current reference point to the same parcel.
What RS and LR Actually Mean
RS generally refers to older survey references from an earlier settlement operation. LR (Land Reforms) typically refers to the later, updated record set that superseded the RS survey in most Mouzas.
Over time, plot numbers can change between these two survey systems — a plot that was Dag number 120 under RS might become Dag number 87 under LR, even though it’s physically the same land. This renumbering is exactly why RS-LR mapping exists as a dedicated service.
Hal Dag vs Sabek Dag
- Hal Dag refers to the current (present) plot number in use.
- Sabek Dag refers to the earlier (previous) plot number from an older survey.
Depending on which document you’re holding, you may need to map Hal Dag to Sabek Dag, or Sabek Dag to Hal Dag, to confirm the two numbers refer to the same parcel.
When You Actually Need RS-LR Mapping
From what I’ve seen helping people verify land, this comes up most often in these situations:
- A seller or family member is showing you an old deed with an RS dag number, but current Banglarbhumi records use LR numbering.
- You’re dealing with inherited or ancestral land where the paperwork spans multiple survey generations.
- A boundary or ownership dispute references an old plot number that doesn’t match today’s Khatian.
- You want to confirm a Mouza map or RoR document is describing the exact same land as an older document you already hold.
Steps to Check RS-LR Information on Banglarbhumi
- Go to the Banglarbhumi portal.
- Open Citizen Services.
- Select RS LR Information.
- Choose District, Block, and Mouza.
- Select the mapping direction you need: Hal Dag to Sabek Dag, or Sabek Dag to Hal Dag.
- Enter the plot number you have.
- Enter the captcha.
- View the results.
The result screen shows the corresponding plot number under the other survey system, letting you confirm whether the old and new references genuinely match the same parcel.
A Practical Example of How This Helps
Here’s the exact situation this tool is built for: a seller shows you an old deed referencing RS Dag 45. When you search current records on Banglarbhumi, you find LR Dag 112 registered in the seller’s name in the same Mouza.
Instead of assuming these are unrelated numbers (or worse, assuming they must be the same land without checking), use the RS-LR mapping tool to confirm the connection directly. If the tool maps RS 45 to LR 112, you now have documented confirmation that both references describe the same parcel.
If the mapping tool returns a different LR number than the one on the current record, that’s a red flag worth investigating further before you proceed with any transaction.
Common Issues When Mapping RS and LR Numbers
| Issue | Likely Cause | Fix |
|---|---|---|
Mapping tool shows no result | Mouza may not have digitized RS-LR mapping data available online | Visit the BL&LRO office with both documents for manual verification |
Multiple LR numbers appear for one RS number | Original plot was subdivided during the LR survey | Cross-check area and boundaries with your deed to identify the correct sub-plot |
Numbers don’t match what the seller claims | Seller may be using an outdated or incorrect reference | Do not proceed until the discrepancy is resolved through the official mapping or the land office |
Mouza name looks slightly different on old documents | Mouza names can have minor spelling variations across survey eras | Confirm using JL number rather than name spelling alone |
FAQs
Is RS-LR mapping available for every Mouza?
Availability depends on how completely a given Mouza’s historical records have been digitized. If the online tool doesn’t return a result, the BL&LRO office can usually confirm the mapping manually.
Which number should I trust more, RS or LR?
For current transactions, ownership, and mutation purposes, the LR (current) record is what matters. RS numbers remain useful mainly for historical comparison and resolving old disputes.
Can RS-LR mismatch block a mutation or sale?
It can cause delays if the department can’t confirm the old and new references describe the same land. Resolving the mapping before you apply for mutation or file a sale deed avoids this holdup.
Final Thoughts
RS-LR confusion is common precisely because West Bengal’s land records span multiple survey generations. Whenever an old document and a current Banglarbhumi record don’t obviously line up, use the RS-LR mapping tool before assuming anything — it’s the fastest way to confirm you’re dealing with the same parcel of land.
