Free Tamil Nadu lookup
Find your survey number by location (சர்வே எண் தேடல்)
The Survey Number Finder checks a map pin, coordinates, a Maps link or a plus code against available Tamil Nadu survey data. A mapped parcel may return a survey number and subdivision; other points may identify only a village. Free, with no sign-in.

Overview
What does the finder look up?
A survey number is the identifier Tamil Nadu’s revenue and survey departments assign to a parcel of land, fixing its place within a village; a subdivision is the suffix added when that parcel has been split. It is sometimes called புல எண் (pula en) in everyday Tamil, and appears as S.F. No. or Sy. No. on older patta and deed forms. Read where the survey number and subdivision sit on each record.
Results are drawn from Tamil Nadu government survey data, the TNGIS cadastral parcel layer where a plot is resolved and its revenue-village boundaries otherwise, published by the Survey and Land Records Department, Government of Tamil Nadu, under the Tamil Nadu Survey and Boundaries Act, 1923.
Use a found number to start an FMB sketch lookup or another record search. Each lookup checks its own availability. If you only know the area, start from the district and taluk pages.
Result guide
What can a lookup return?
- Survey details found
- The point sits inside a parcel the cadastral layer has drawn. You get its survey number and subdivision.
- This point touches more than one parcel
- Your point sits where parcels meet. Compare each with your documents.
- The sources gave different numbers
- Two sources returned different numbers for this point. Compare each with your documents.
- Village found, no survey number here
- The source knows this village but has no parcel drawn at this point. Move the pin onto the land itself, or use the number from your document.
- No parcel data at this point
- TNGIS parcel data covers Tamil Nadu. This point is outside the area it has drawn, so there is no survey number to show.
- The parcel source didn't answer
- Your point is kept. The parcel source didn't answer this time; that is a source outage, not a missing parcel.
How it works
How do I copy a location from Maps?
- Open Google Maps or Apple Maps and place a pin inside the land.
- Copy the pin’s latitude and longitude, or share the location to yourself to get its link.
- Paste the numbers or the link into the finder’s search field. A full plus code works too.
- A short link from the Maps share sheet works too — paste it as it is.
- The finder shows the survey number and subdivision for that point, free and with no sign-in.
Reading a result
What does the result mean?
Use the returned details to search Patta chitta, A-register extract, FMB sketch, TSLR extract, TSLR sketch, Encumbrance certificate, Patta chitta report, A-register report, Village Map, Block Map, CMDA Land Use Map, Municipal Property Tax Receipt, Chennai Property Tax Receipt, Panchayat Property Tax Receipt, Panchayat Water Tax Receipt.
Finding a map match does not confirm that any of these records is available.
An example number
Example only: a result showing survey 181 and subdivision 5A2 refers to 181/5A2 within the returned village. Keep its district, taluk and village with the number.
If your document says 181/5A1, that suffix differs. Check the document and parcel before starting a record search; do not replace it with the map result automatically.
A village-only result has no resolved parcel number. Read the number from your patta, deed or sketch instead.
Map data can be incomplete or out of date. Phone location can also fall on a neighbouring plot.
Check the returned number against your deed or FMB sketch.
Urban results may identify a town-survey block rather than an exact plot. Keep the ward and block with the number.
Find a survey number on your documentsWhat this lookup cannot establish
A survey number locates land in the revenue records. It does not by itself establish ownership, possession or an on-ground boundary. Reconcile it with the registered deed, the FMB sketch and professional advice where needed.
Questions
Before you start.
What people ask before their first lookup: whether an address is enough, whether you need to sign in, and what the result does and does not prove.
Can I find a survey number from just an address or location?
Yes, when the point you choose falls inside a parcel the TNGIS cadastral layer has drawn. The finder returns the survey number and subdivision for that point; where the layer has no parcel, it tells you which village the point is in instead.
Does the finder also give the subdivision number, or just the base survey number?
It gives both when they apply. If the parcel at your point has been split, the result includes the subdivision suffix along with the base number — 5A2 after 181, for example — so you get the exact slice of land rather than the original undivided block. Where there is no subdivision, you get the plain survey number.
I already have a patta or deed. Can I read the survey number off that instead?
Yes, and it is worth doing both. On a patta or a deed the number is printed in the parcel description, often as S.F. No. or Sy. No.; the finder tells you which number the cadastral layer holds for the land itself. Checking one against the other is how you catch a document that describes a different parcel.
Do I need to sign in to use the finder?
No. The finder is free and needs no sign-in. You sign in with a one-time code by SMS only if you go on to order a record for the land.
Is the result proof of ownership or a legal boundary?
No. It is an indicative match from government survey data. Check the number against your deed or FMB sketch before relying on it.
Are the coordinates I paste stored?
No. Your search and coordinates are not saved and are not added to the page URL. A pasted Google Maps short link goes to our server, which follows it once to read where it points and keeps neither the link nor the place it names. A place name you search for is sent to Google to find it. The map view itself reaches Google and TNGIS to draw tiles.
What does a town-survey block result mean?
In urban areas the source may identify the block a point sits in rather than the exact plot. Keep the ward and block with the number when you look up a TSLR record.
