Survey Numbers: How to Check the Project You Visited Is the Land That Was Registered

Most buyers run one check on a project's registration: does the number exist. It is a reasonable check and it is the weakest one available, because a registration that exists can still cover land other than the land you stood on.

A registration attaches to specified survey numbers. That is the fact this whole post turns on. If you can match the survey numbers on the certificate to the survey numbers of the land you were shown, you have run the check that catches the serious problems — a registered phase adjoining an unregistered one, a show unit built on a parcel the certificate does not mention, a project marketed under a locality name that belongs to a different village entirely.

Why a registration attaches to survey numbers, not to a name

A project's name is a brand. A promoter's trading name may differ from the registered legal entity behind it. A locality name is whatever the market has decided to call the area this year, and on a corridor with several similar-sounding villages that is a genuinely unstable description.

Survey numbers are none of those things. They are the units the revenue record is kept in, they change only through a recorded process of sub-division, and they are what a registration, a sale deed, an encumbrance search and a survey sketch all use. Everything checkable about a piece of land is indexed on them.

Which is why the sequence below never asks whether a name matches. It asks whether a number does.

Finding the survey numbers on the certificate and the register

Two sources, and you want both because they should agree.

1. The registration certificate itself. Ask the promoter for a copy. It carries the registration reference, the promoter's registered name, validity dates and the land the registration covers.
2. The regulator's public register entry. The promoter's own filings sit on the state regulator's site, under the registration reference. Section 11(1) of the Real Estate (Regulation and Development) Act, 2016 requires the promoter to create the project's page on the Authority's website and enter the project details there, and section 11(2) requires the promoter to prominently display that web page address in its advertisements — so the address of the entry is itself something you are entitled to be given.

Read the survey numbers off both and write them down exactly as printed, including sub-division suffixes and the village name. The suffix is not decoration: 27 and 27/1 are different parcels.

A worked example from our own paperwork, so the exercise is checkable rather than theoretical. THE1's K-RERA certificate records the land as Sy. Nos. 27/1 & 27/2, Sompura Village, Sarjapura Hobli, Anekal Taluk. That single line carries the parcel, the revenue village, the hobli and the taluk — enough to order every record about the land without asking us for anything further. Every SUYUG registration is transcribed the same way, from the certificate, on the RERA page.

Matching them against the revenue record for the village

Now take the numbers to the state's own land records, using the village name from the certificate rather than the locality name from the brochure.

• Confirm the parcel exists under that number in that village. A number that returns nothing usually means the village name is wrong, and village names are spelt several ways.
• Check the extent. The area on the record against the area the project claims for the parcel. A material difference is a question, not necessarily a problem.
• Check the classification. Whether the land is recorded as agricultural or as converted for non-agricultural use, and if converted, under whose order.
• Order an encumbrance certificate for the same survey numbers, for a period you choose rather than the period you are offered.

The point of doing this on the certificate's numbers rather than the seller's description is that you are now searching for the land the regulator was told about.

Locating the survey number on the ground

The last mile is physical, and it is the step almost nobody runs.

Take the survey sketch for the parcel — in Karnataka the survey document for a part-parcel transfer, in Tamil Nadu the field measurement book sketch — and orient it on site using the adjoining survey numbers named on it. Then walk the boundary of the parcel the certificate describes and see whether the site you were shown sits inside it.

What you are looking for is simple: land you were walked across that is outside the registered parcel. A marketing suite, a landscaped approach, an amenity block, a "future phase" behind a hoarding. None of those is necessarily improper. All of them are things you should be able to place on a map.

Phases: when part of a site is registered and part is not

Phasing is legitimate and common. A promoter registers a phase, builds it, and registers the next one later. The exposure for a buyer is not phasing itself; it is being sold in an unregistered phase while looking at a registered one.

Section 3(1) of the Real Estate (Regulation and Development) Act, 2016 bars a promoter from advertising, marketing, booking, selling or offering for sale in a project within its scope that is not registered. So the questions are narrow and answerable:

1. Which phase is the unit or plot I am being offered in?
2. Which survey numbers does that phase sit on?
3. Is that phase registered, and under which reference?
4. If it is not yet registered, on what basis am I being asked to pay anything?

A promoter selling only what it has registered can answer all four in a paragraph.

What an extra or missing survey number tells you

Two ordinary explanations, before you assume the worst

Most discrepancies found by this exercise are not misconduct, and treating every one as a red flag will cost you a sound purchase.

The first ordinary explanation is spelling. Revenue village names are transliterated, and the same village appears with an extra vowel, a doubled consonant or a different ending depending on which clerk typed it. A certificate reading one way and a portal reading another is usually one village, and the fix is to search the variants rather than to conclude the land does not exist.

The second is sub-division. Land that was one survey number when a project was conceived may have been sub-divided since, so a certificate filed earlier can carry the parent number while the current record carries the parts. That is a recorded process with an order behind it, and the order is a document you can ask for. What distinguishes it from a real problem is that somebody can produce the paper trail linking the two descriptions.

What is not ordinary is a description that nobody will reconcile in writing. A promoter who answers a survey-number question with a locality name, a phone call or a reassurance has not answered it. Put the question in an email, name the number you read on the certificate, name the number you were given for the plot or unit, and ask which record links them.

The three-step check, condensed

1. Read the land off the registration. Survey numbers, sub-divisions, village, hobli or firka, taluk — from the certificate and from the regulator's register entry, and confirm the two agree.
2. Search the record on those numbers. Revenue record, extent, classification and an encumbrance certificate you ordered yourself, all keyed on the certificate's description rather than the brochure's.
3. Stand on it. Orient the survey sketch on site and confirm that what you were shown sits inside the parcel the registration names.

An afternoon of work, no professional required for the first pass, and it is the check that finds the things a lawyer's title opinion is not always asked to look for — because a title opinion answers whether the seller owns the land, and this answers whether the land you saw is the land in question. Both are worth having. The order in which every document in a purchase arrives is set out in the buyer guide.
