  • May include a subdivision number: If a survey parcel is divided into smaller portions, each portion may be assigned a subdivision number linked to the original survey number.
  • Can vary by state: Land records are maintained by state authorities, so the terminology, format, and process for finding a survey number may differ from one state to another.

  • Survey Number: A unique number assigned to a parcel of land in government land and revenue records. It is used to identify the land for purposes such as ownership records, registration, taxation, and determining boundaries.
  • Door Number: A number assigned by the local municipal or civic authority to a building, house, or unit. It is mainly used as part of the property's postal and physical address.
  • Plot Number: A number given to an individual plot when a larger parcel of land is divided into smaller plots as part of an approved layout or development.
Aspect Survey Number Door Number Plot Number
Identifies A parcel of land A building, house, or unit An individual plot within a layout
Main Purpose Land records, ownership, registration and taxation Address and location identification Identifying a specific plot in a layout
Assigned by Government revenue/land records authority Local municipal or civic authority Planning authority or as part of the approved layout

What Is a Survey Subdivision Number?

A survey subdivision number is an additional number used to identify a specific portion of a land parcel when the original survey number has been divided into smaller portions. This can happen when land is subdivided for sale, inheritance, development, or other purposes.

For example, if Survey Number 45 is divided into smaller portions, they may be recorded as 45/1, 45/2, 45/3, etc., depending on the state's land-record system.

Before buying a property, verify the survey number against the official land records. This can help you confirm that the property you are purchasing corresponds to the land described in the seller's documents.

You can verify it through the following methods:

  • Compare the survey number: Check whether the survey number and subdivision number in the sale deed match the details in the Patta, Chitta, and other available land records.
  • Verify the property details: Compare the recorded land area, boundaries, location, and other identifying details with the actual property. This helps ensure that the documents refer to the same piece of land.
  • Check the official land records: Use the relevant state land-records portal to cross-check the available property information. For properties in Tamil Nadu, you can refer to the Tamil Nadu e-Services Land Records portal.
  • Check for discrepancies: If the survey number, subdivision number, land extent, or boundaries differ between documents, do not ignore the mismatch. Ask the seller to clarify the discrepancy and verify the records with the concerned authority.
  • Visit the Taluk or Revenue Office if required: If the information is unclear or the records are not available online, visit the concerned Taluk or Revenue Office with the property documents for further verification.

Important: Do not rely solely on the survey number provided by the seller. Verify it against the official records and other property documents to ensure that the land you are purchasing matches the property described in the documents.

What to Do If the Survey Number Is Incorrect?

It is more common than you think: the ledger number does not match the sale deed or what the seller narrated to us. Some of the typical reasons are:

  • Typographical error: The number was typed incorrectly while entering or copying the number.
  • Old survey number: This is a citation to a number that is out of date.
  • New survey number: The property was resurveyed, and older documents do not reflect the change.
  • Subdivision mismatch: You might be looking at the large number when you also need to look at the smaller number in the subdivision.
  • Resurvey: The numbers can change on the pack-village when the government undertakes re-surveys.
  • Record or data-entry issue: Occasionally it’s simply a mistake in how the record was kept.

If you notice a discrepancy, do not ignore it. Go to the Taluk office or e-Services page, raise the issue, and give the old number with the subdivision particulars so that correction can be made before you buy and not after.

Old Survey Number vs New Survey Number

An old survey number refers to the number recorded for a parcel of land in earlier land records or surveys. When the land is resurveyed, subdivided, or land records are updated, the same property may be assigned a new survey number or subdivision number, depending on the applicable state land-record system.

The old and new numbers may both appear in property documents, so it is important to understand how they are connected.

  • Old Survey Number: The number recorded in earlier land or revenue records. You may find it in older sale deeds, patta records, or other historical documents.
  • New Survey Number: A number assigned or updated during a resurvey, subdivision, or revision of land records. It helps authorities identify the property under the updated records.
  • Survey Number Changes After Subdivision: When a larger survey parcel is divided into smaller portions, the original survey number may be retained with different subdivision numbers, or the numbering may be revised according to the state's land-record system.
  • Verify the Link Between Old and New Numbers: If your property documents mention both numbers, verify the connection through the relevant land records or revenue authority before using the new survey number for registration or other legal purposes.

Tip: If the survey number mentioned in your old property documents does not match the current land records, do not assume that the records are incorrect. Check the state's official land records or consult the concerned revenue authority to confirm whether the property has been resurveyed, subdivided, or renumbered.
