Overview
Andaman & Nicobar Islands maintain cadastral surveys where each plot has a unique survey number or Patta (occupancy record). The A&N Administration Revenue Department holds all land records. However, significant portions of the islands are tribal reserves, national parks, and protected forests—these areas are restricted and not available for private ownership.
If your land is outside restricted areas, the survey number is your link to official ownership records and boundary proof. However, land availability and transactions are tightly regulated by the A&N Administration. 1acre is building map-based search for A&N—coming soon.
One plot, many names — what ‘survey number’ means here
1. Survey Number:
The unique identifier assigned to a surveyed plot in the A&N Administration records; used for boundary identification.
2. Patta:
The occupancy record showing holder rights to a plot; the primary document for land ownership claims in A&N.
3. Tribal Reserve Area:
Areas designated for tribal populations; not available for private ownership or transaction. Covers significant portions of the islands.
4. Protected Forest / National Park:
Areas under conservation; no private land ownership permitted. Check before buying land in A&N.
