Tamil Nadu A-Register Online – Check Land Area and Classification Using Your Phone
Digital land-record services have made it easier for people in Tamil Nadu to access important information about their property. One of the useful revenue records for checking survey-based land information is the A-Register.
The Tamil Nadu A-Register contains important details connected with land parcels in a village. Depending on the applicable record, it can help users understand the Survey Number, Subdivision Number, land extent and classification recorded in the revenue system.
Tamil Nadu has computerized basic land records through the Tamil Nilam system, allowing citizens to access applicable land information electronically. This means that many users can perform an initial land-record check from a mobile phone instead of depending only on old paper documents.

This guide explains Tamil Nadu A-Register Online, how to check land area and classification using your phone, and how A-Register information relates to Patta/Chitta, FMB and other land records.

What Is Tamil Nadu A-Register?
The A-Register is an important village-level revenue record maintained in Tamil Nadu.
It provides survey-based information about land within the applicable revenue village. Rather than focusing only on the name associated with a landholding, the A-Register can provide useful information connected with the actual parcel.
This makes it useful when checking a Survey Number, Subdivision Number, land extent or classification.
A-Register information can also be compared with Patta/Chitta, FMB and registered property documents when verifying land details.
Why Is the A-Register Important?
A land parcel can have several pieces of information associated with it.
The owner’s document may contain a Survey Number and Subdivision Number, while the revenue records contain additional information about the land.
The A-Register provides another source for comparing these details.
For example, if you want to know how a parcel is classified in the revenue record or what extent is recorded against a survey reference, the A-Register can be useful.
It is particularly valuable when information from multiple land records needs to be cross-checked.
What Details Can an A-Register Show?
The exact information can depend on the applicable record and location.
Commonly relevant details include the Survey Number and Subdivision Number, which identify the parcel in the survey system.
The record can also contain the extent or area of the land and its revenue classification.
Additional revenue-related particulars may appear depending on the record.
When checking A-Register information, make sure every detail corresponds to the correct Village and parcel rather than relying on a Survey Number alone.
What Is a Survey Number?
A Survey Number is a key identifier assigned to surveyed land.
It helps locate a particular parcel within the revenue and survey records of a village.
Survey Numbers appear across different Tamil Nadu land records and property documents.
If you are checking the A-Register, keep the Survey Number from your registered deed, Patta or another reliable official document available.
Remember that the same numerical reference can occur in different villages. The Village and other location details are therefore equally important.
What Is a Subdivision Number?
A larger Survey Number can be divided into smaller individual parcels.
A Subdivision Number identifies the applicable portion after such division.
For example, a property document may contain a main Survey Number followed by a specific subdivision reference.
When a subdivision exists, checking only the main Survey Number may not be sufficient to identify the intended land.
Always verify the complete Survey and Subdivision reference against the A-Register and other applicable records.
What Does Land Area or Extent Mean?
The A-Register can provide information about the recorded extent of land associated with the relevant survey parcel.
This information is important when comparing revenue records with a registered deed or other property document.
If a Survey Number has several subdivisions, check the extent against the specific subdivision rather than assuming that the total Survey Number area belongs to one property owner.
For property verification, the area should also be compared with other relevant official records.
What Is Land Classification?
Land classification describes how land is categorized in the applicable revenue record.
Different classifications can appear depending on the nature and status of the land.
For example, official Tamil Nadu records use categories and descriptions relating to wet land, dry land, Natham and various types of government or Poramboke land in applicable contexts.
The classification shown in the relevant revenue record can be important when examining a property.
Do not assume that the way land is physically being used today automatically changes its official revenue classification.
How to Check Tamil Nadu A-Register Online
Start with the applicable official Tamil Nadu land-record service.
Select the option for viewing the relevant land record or A-Register details.
Choose the correct District.
Select the Taluk.
Choose the Revenue Village.
Enter or select the Survey Number.
Provide the Subdivision Number where applicable.
Complete any verification requested by the current system.
Review the available A-Register information and compare it with your property documents.
The exact screen and fields can change when government services are updated, so follow the options displayed on the current official portal.
How to Check A-Register Using Your Phone
You can use a suitable mobile browser to access applicable Tamil Nadu digital land-record services.
Before starting, keep your registered deed, Patta or another reliable document nearby.
Identify the correct District, Taluk, Village, Survey Number and Subdivision Number.
Enter these details carefully.
Once the record is displayed, zoom in if necessary and compare the land extent and classification with your documents.
For important transactions, do not depend only on a screenshot saved on your phone. Verify the latest applicable official record.
A-Register vs Patta/Chitta
The A-Register and Patta/Chitta are related but should not be treated as identical records.
A-Register is particularly useful for survey-based village land particulars such as parcel references, extent and classification.
Patta/Chitta provides relevant landholding and revenue information.
When checking a property, comparing both records can help identify inconsistencies.
The Survey Number and Subdivision Number appearing in your documents should correspond with the applicable revenue records.
A-Register vs FMB
An FMB or Field Measurement Book sketch provides measurement and graphical information about a surveyed parcel.
A-Register is mainly a textual revenue record.
FMB provides spatial and measurement-related context.
Therefore, if the A-Register shows the Survey Number and recorded extent, an FMB sketch may help you understand the shape and measurements associated with that parcel.
However, an FMB sketch should not automatically replace an official physical survey when an exact boundary is disputed.
A-Register and Patta Transfer
When land changes hands through an applicable transaction, Patta Transfer may be required to update the revenue record.
Tamil Nadu provides an Online Patta Transfer system for applicable cases.
A transfer can involve a full field, joint Patta or subdivision depending on the circumstances.
After the applicable process is completed, compare the updated Patta details with the A-Register and Survey/Subdivision information.
If only part of a larger Survey Number was transferred, subdivision details can become especially important.
How to Check Land Classification Before Buying Property
Before buying land, identify the exact Survey and Subdivision Numbers from the seller’s documents.
Check the applicable A-Register.
Review the recorded land extent.
Check the classification appearing in the revenue record.
Compare the information with the Patta/Chitta.
Review the FMB where relevant.
Also compare these records with the registered deed and other legally relevant property documents.
If the classification or area does not match, obtain clarification through the appropriate official channel before relying on the information.
What If the Land Area Does Not Match?
First verify that you selected the correct Village, Survey Number and Subdivision Number.
Compare the A-Register with the registered deed, Patta and FMB.
A mismatch may require examination of older survey records, subdivision information or subsequent record updates.
Do not simply choose whichever document shows the larger area.
For an important discrepancy, the applicable Revenue or Survey authority may need to examine the records and determine the correct procedure.
What If the Land Classification Looks Incorrect?
Confirm that you are viewing the correct parcel.
Check older and current official revenue records where available.
The physical use of a property and its recorded revenue classification are not necessarily the same thing.
If there is a genuine record error or a legally recognized change that has not been reflected, use the appropriate official procedure rather than relying on an unofficial website or agent.
Is A-Register Proof of Ownership?
The A-Register is an important revenue record, but it should not automatically be considered standalone conclusive proof of legal ownership.
A complete property verification can involve the registered sale deed, Patta, inheritance or succession documents, gift or partition deeds, court orders, encumbrance information and applicable survey records.
A-Register information is best used as one part of a broader property-verification process.
