Your property registration gets rejected at the sub-registrar’s counter. The reason: the survey number on the sale deed doesn’t match the A-Register entry. Or perhaps a bank has held up your agricultural loan because the guideline value you quoted was two revisions old.
In Tamil Nadu, these three records the A-Register, the guideline value, and the survey number decide whether a land transaction moves forward or stalls.
This guide explains what each record contains, how they relate to one another, and how to pull them up through the Tamil Nadu e-Services portal and TNREGINET so you can catch a mismatch before it costs you a deal.
What Is an A-Register in Tamil Nadu Land Records?
The A-Register also called the A-Extract is the village-level land account maintained by the revenue department for every survey number in a village.
Where a Patta records who owns a parcel, the A-Register records what that parcel is.
A typical entry carries twelve columns: survey number, sub-division number, land classification (wetland, dryland, or manavari), soil type, assessment rate, irrigation source, and the name of the pattadar on record.
For agricultural land, the Adangal which tracks cultivation and crop details season by season is read alongside it.
This record earns its importance during due diligence. If the pattadar name in the A-Register differs from the name on the sale deed,
or if the land classification has shifted without paperwork to explain it, banks and lawyers treat that as a title defect worth resolving before money moves.
Understanding Guideline Value: The Government’s Minimum Property Rate
Guideline value, or circle rate, is the floor price at which a property can be registered in Tamil Nadu.
Stamp duty and registration charges are computed on whichever figure is higher your actual transaction value or the guideline value for that property..
Under-declaring the sale price to save on stamp duty does not work, because the registrar will simply apply the guideline rate.
The Registration Department fixes these rates by location. Developed areas with proper street addresses are usually rated by street number.Land in developing or rural pockets is rated by survey number instead.
Rates are revised periodically through government notification, and the TNREGINET portal retains older entries for reference which is exactly where people slip up.
A rate you checked a year ago may no longer apply. For any live transaction, confirm the current figure on the portal on the day you finalise terms.
How to Check Guideline Value on TNREGINET
- Open TNREGINET and select the Guideline Value option from the main menu.
- Pick the date range for the valuation you need. The portal holds historical data, so older rates remain visible if you are researching a past transaction.
- Choose your search route street number for developed localities, survey number for land and developing areas.
- Fill in the location fields: district, taluk, village, and then the specific street or survey number.
- Read the result and, if useful, run the calculate option to work out the total guideline value for your plot’s area and unit of measurement.
One practical note: if you are searching by survey number in an area that has since been brought under a town survey, the result may not appear at all.
In that case, switch to the street-based search or check the TSLR route described below.
What Is a Survey Number and Why It Matters
A survey number is a unique identifier the revenue department assigns to a land parcel. It is the hinge on which every other Tamil Nadu land record turns.
Without the correct number, you cannot apply for a Patta, request an Encumbrance Certificate, or complete a registration.
You will find it printed in sale deeds, Patta certificates, Chitta records, property tax receipts, and Adangal extracts.
Two plots in the same village will never share a survey number that is how the system keeps transactions,
loan processing, and ownership disputes from collapsing into confusion.
There is a split you need to know about. Rural land is identified by village survey numbers tied to Patta records. Land inside notified town limits falls under the Town Survey Land Register (TSLR), which uses ward and block references instead.
If you are buying a flat or plot in Chennai, Coimbatore, or Madurai, the TSLR extract usually carries more weight with registrars and banks than a Patta does.
How to Find Your Survey Number
- Start with your own documents. The survey number sits near the top of the property description in a sale deed. Older Patta copies and property tax receipts also carry it.
- Ask the Village Administrative Officer (VAO). For rural parcels, the VAO office holds village-level records and can identify the survey number for a specific holding.
- Search the Tamil Nadu e-Services portal. If you have the owner’s name or Patta number, the land records search options there can lead you to the associated survey number.
- Cross-check with the FMB sketch. The Field Measurement Book sketch maps plot boundaries and links them to survey numbers useful when measurements or boundaries are disputed.
For urban properties where all you have is an address or a landmark, private tools claim to map addresses to survey numbers, but nothing beats your registered documents or a visit to the local sub-registrar or taluk office.
How to Download the A-Register Extract Online
The A-Register extract is free to view and download through the Tamil Nadu e-Services portal.
- Open the Tamil Nadu e-Services portal and pick your language English or Tamil.
- Select “View A-Register Extract (Rural / Natham)” from the land record services listed.
- Choose district, taluk, and village from the dropdowns.
- Enter the survey number and sub-division number exactly as they appear on your Patta or sale deed.
- Give your mobile number and clear the OTP and captcha verification.
- Submit and the extract appears with the full land details.
- Download or print the PDF. A unique reference number in the footer lets banks and agencies verify it independently.
Two pitfalls worth knowing. First, the portal will not warn you if you have typed a valid-but-wrong sub-division number it may simply return a different parcel’s record that looks plausible.
Cross-check the pattadar name and extent against your deed before trusting the output. Second, if you request the extract late on a Friday or during a server maintenance window,
the OTP may time out repeatedly; try again on a working morning rather than assuming your number is wrong.
When you read the extract, look hard at the land classification. Land marked as government land or poramboke cannot be bought and sold as private property, no matter what the seller’s documents suggest.
Common Mistakes to Avoid When Checking Land Records
Entering the wrong survey or sub-division number. This is the single largest cause of failed searches. Copy the number from an official document never type it from memory.
Treating Patta and A-Register as interchangeable. Patta shows current ownership. A-Register shows classification, extent, and the village-level history. Checking only one leaves you half-informed.
Skipping the TSLR for urban property. A Patta can exist for urban land without carrying the town survey detail that registrars and banks want to see.
Ignoring mismatches between records. When the pattadar name in the A-Register does not match the Patta, or a survey number cannot be reconciled across documents,
pause the transaction. Mismatches usually point to unupdated records or genuine title defects.
Relying on one record. A proper check typically runs across Patta, Chitta, A-Register, Adangal, FMB sketch, and the Encumbrance Certificate together.
Frequently Asked Questions
What is the difference between A-Register and Patta?
Patta is the revenue department’s ownership record, naming the person in whose favour the land stands.
A-Register is the village land account giving classification, extent, and historical detail for each survey number. Patta tells you who owns it; A-Register tells you what it is.
Can I check guideline value without a survey number?
Yes in developed areas with proper street addresses, guideline value is checked by street number.
For land in developing or rural areas, the survey number is typically the primary reference.
Why does my survey number show no results on the portal?
Usually one of three reasons: the survey or sub-division number was entered incorrectly, the parcel falls under a different administrative boundary than the one you selected, or the records have not been digitised or updated.
Rechecking the number against your sale deed and confirming the district, taluk, and village selections resolves most cases.
Is the A-Register extract available for urban properties?
The A-Register covers rural and Natham (village residential) land. For properties inside town survey limits, the Town Survey Land Register is the relevant record.
How often is guideline value revised in Tamil Nadu?
The state government revises guideline values periodically based on market conditions and administrative review.
The schedule is not fixed, so confirm the current rate on the official portal before finalising any transaction.
What should I do if my Patta and A-Register show different details?
Treat it as a stop signal. It may mean the Patta was updated while the village register was not, or that a classification change never carried through.
The practical route is to take both documents to the local taluk office or a licensed document writer and have the discrepancy reconciled before you proceed.
A Final Note on Verification
Portals make Tamil Nadu land records easier to reach, but they do not make them self-correcting. The A-Register, guideline value, and survey number each answer a different part of the same question is this land what it claims to be? Pull all three,
read them against each other, and treat any mismatch as a reason to slow down rather than push ahead. If a discrepancy surfaces close to your registration date,
remember that the sub-registrar’s office works on its own timeline; raising the issue early gives you room to fix the record instead of losing your slot.
