How to Find Survey Number Online in Tamil Nadu

A **land survey number** is a unique identifier assigned to a specific parcel of land by the Revenue Department. In Tamil Nadu, having the correct survey and subdivision number is essential for obtaining a Patta Chitta, running a Villangam EC online search, or verifying guideline values. If you do not know your property's survey number, you can retrieve it online via the official Tamil Nadu land records portal. This guide explains how to find your survey number using taluk and village parameters.

Why is the Survey Number Critical?

The survey number serves as the primary index key for property administration in India. You need it to:

Verify Land Ownership: Checking patta records to confirm who owns the land in the government database.
Run Encumbrance Checks: Checking the SRO registry database to confirm there are no mortgages on the plot.
Confirm Boundaries: Obtaining the Field Measurement Book (FMB) map to identify land dimensions and neighbors.
Avoid Registry Disputes: Ensuring that the property boundaries in the sale deed match the survey records.

How to Find Your Survey Number Online

The Tamil Nadu government offers a public utility portal (**eservices.tn.gov.in**) to retrieve land records. Follow these steps to find your survey number:

Step 1: Open the e-Services Portal

Go to the official website: eservices.tn.gov.in.

Step 2: Navigate to View Patta Chitta

Select **"View Patta & FMB / Chitta / TSLR Extract"** from the home menu options.

Step 3: Select District, Taluk and Village

Choose your District, Taluk, and the specific Village where the property is located. Select land type as Urban or Rural.

Step 4: Search by Owner Name

If you do not know the survey number, select "Search by Owner Name". Enter the name, solve the security captcha, and submit. The system will display the matching Patta details, including the survey and subdivision numbers.

Retrieving Survey Numbers from Deed Documents

If you cannot find your records on the online database (which can occur with older records that are not yet digitized), inspect your physical sale deed. The survey and subdivision numbers are always listed in the **"Schedule of Property"** section at the end of the deed. This section provides a detailed description of the property, including its boundaries, measurements, street name, and ward numbers.
