What is a Land Survey Number & How to Check It Online?
A Clear Guide by Raaj Real Estates – Trusted Experts in Villa Plots in Chennai
If you’re planning to buy villa plots in Chennai — especially in fast-growing areas like Meppur, Poonamallee, or Thirumazhisai — one crucial detail you must verify is the land survey number. It’s more than just a number; it serves as legal proof of a land parcel’s identity, boundary, and ownership. Whether you’re investing or building your dream home, knowing how to check the land survey number ensures a smooth and secure property transaction.
🏷️ What is a Land Survey Number?
A land survey number (also called a cadastral number) is a unique identifier assigned to every plot of land by the Revenue Department. It helps maintain official land records, track legal ownership, and clearly define property boundaries — whether it’s in an urban layout or a gated community in the suburbs of Chennai.
🔑 Survey Number vs Door Number – What’s the Difference?
| Survey Number | Door Number |
|---|---|
| Identifies a land parcel | Identifies a building or flat |
| Used for ownership, tax records, and land transactions | Used for addressing and postal services |
| Assigned by Revenue Department | Assigned by Municipality or Corporation |
| Permanent unless land is split or merged | Can change due to city planning |
If you’re purchasing plots for sale in Poonamallee or surrounding areas, the survey number is the key reference in all legal documents.
📌 Why Survey Numbers Are Important in Land Transactions
When investing in villa plots near Meppur, Poonamallee, or Thirumazhisai, the survey number ensures:
Legal proof of property ownership

Easy resolution of any land disputes
Never proceed without checking and verifying the land survey number — especially when buying CMDA & RERA approved plots.
