Survey Number Check Tamil Nadu 2026: Find a Survey Number on the Map, with FMB and Patta (சர்வே எண்)

What is a Survey Number?

A survey number is a unique identifier assigned to each parcel of land by the Revenue Department during land surveys. It serves as the primary reference for all land-related documentation, transactions, and official records in Tamil Nadu. Every piece of land, whether agricultural, residential, or commercial, has a designated survey number that helps in precise identification and location.

Importance of Survey Numbers

• Legal Identification: Survey numbers are essential for all legal transactions involving land, including sale, purchase, and inheritance.
• Property Documentation: Required for obtaining patta, applying for loans, and registering property documents.
• Tax Assessment: Used by authorities to assess and collect property taxes accurately.
• Dispute Resolution: Helps in resolving boundary disputes and establishing clear demarcation of properties.
• Development Planning: Essential for urban planning, infrastructure development, and land use management.

Understanding Survey Number Format

In Tamil Nadu, survey numbers follow specific formats:

• Main Survey Number: The primary number assigned to the original land parcel (e.g., 123)
• Sub-divisions: When land is divided, sub-division numbers are added (e.g., 123/1, 123/2)
• Further Sub-divisions: Can have multiple levels (e.g., 123/1A, 123/1B)
• Old vs New Survey Numbers: Some areas have both old and new survey number systems

Frequently Asked Questions

What is a survey number?

A survey number is the number the Revenue Department gave a parcel of land when the village was surveyed. Every patta, FMB sketch, encumbrance certificate and sale deed refers to it. When a parcel is split, sub-divisions are added, so 123 becomes 123/1, 123/2 or 123/1A.

What is the difference between a survey number, a sub-division and a patta number?

The survey number identifies the land itself and never changes. A sub-division is a part of that survey number created when it was split. A patta number identifies the holder in the revenue register, and one patta can cover several survey numbers while one survey number can move between pattas as it is sold.

How do I get the FMB village map for a survey number?
