Short answer: a survey number or plot number usually points to a parcel in a state’s revenue and cadastral system, while a khata number commonly identifies an account or holding that may contain several parcels. India has no single nationwide naming scheme: revenue departments define fields and relationships state by state. Before paying for land, match the sale deed, current Record of Rights (RoR), mutation history and cadastral map rather than relying on any number alone.
The Department of Land Resources (DoLR) distinguishes textual RoRs, which record rights and transactions, from spatial records, which are maps establishing boundaries on the ground. You need both types of evidence for a meaningful property check: DoLR’s Citizen Centric Services guidance explains the distinction and the role of title-deed verification.

Survey, plot and khata numbers at a glance
| Identifier | Usually identifies | Where you may see it | What it does not prove by itself |
|---|---|---|---|
| Survey number | A surveyed land unit or parcel reference, sometimes with subdivisions or old and revised numbers. | Revenue records, cadastral registers, sale deeds and state land-record portals. | That the seller has undisputed title, that the boundaries on the ground are correct, or that the number is current. |
| Plot number | A parcel reference used by a particular state, development authority, layout or portal. | Land records, approved layouts, municipal or development records and online search forms. | That “plot” is universally synonymous with “survey”; the relationship depends on the state and record system. |
| Khata number | An account or holding associated with a person or holder; it may group multiple survey entries. | Khata, holding or account registers and state services such as Gujarat’s VF8A details. | That it names one physical parcel or conclusively establishes ownership. |
| ULPIN/Bhu-Aadhar | A geospatial parcel identifier generated from coordinates, detailed surveys and geo-referenced cadastral maps. | Participating state or Union territory portals. | That it has replaced local survey, plot or khata references everywhere. |
Use the label printed on the document, but also inspect the surrounding fields: village or locality, sub-number, area, holder name, land type, map reference, mutation entry and document date. Those fields reveal what the number actually refers to in that jurisdiction.

A survey number is a reference assigned when land is surveyed and entered in a revenue or cadastral record. It identifies a surveyed unit within a village or other local administrative area. A large original survey unit can later be divided into sub-numbers, and a resurvey can create revised or legacy references. The exact format, punctuation and hierarchy are state-specific.
#1 Best Overall
For example, a record might show a main number with a subdivision, but the meaning of that suffix can differ between states. Treat the complete entry—not just the digits before or after a slash—as the identifier. Check whether the deed and current RoR call it a survey number, khasra number, dag number or another local term.
The DoLR-supported Study on Quality of Land Records (Andhra Pradesh, Chhattisgarh, Kerala & Lakshadweep) describes Khasra in Chhattisgarh as a village-wise record of survey numbers containing area and holder-related information: the 2024–25 study PDF. That description illustrates one state’s arrangement; it is not a national definition.
Survey number and a mapped boundary
A survey number becomes useful for a buyer when it can be connected to the corresponding cadastral map and the parcel on the ground. A textual entry may state an area and holder, while the spatial record shows shape, adjoining parcels and boundary position. The number alone cannot tell you whether a wall, road or fence has been placed in the correct location.
What a plot number means
“Plot number” is a parcel reference used by some state land-record systems and by layout or development records. It may be the number a portal expects when you search for land, but that does not make it interchangeable with “survey number” throughout India.
Odisha’s official Bhulekh FAQ, for instance, says citizens can retrieve land details using a Khatiyan number, plot number or tenant details. The same service provides map viewing through a separate MapView function: Bhulekh Odisha FAQ. This demonstrates that a plot number can be an official search key while the map is a separate part of the verification process.
In a plotted development, a layout’s plot number may be assigned for marketing or planning and may coexist with the underlying revenue survey number. Ask the seller or issuing authority to show the approved layout and the cross-reference to the revenue parcel. A plot number printed on a brochure, tax receipt or allotment letter is not sufficient evidence that the described land is legally transferable.
What a khata number means
A khata number commonly identifies an account or holding linked to a person, family or pattadar. One account can contain several survey or parcel entries, so it often answers “which holding or account contains this land?” rather than “which single physical parcel is this?” The usage is not uniform: some states use related terms such as khatauni, khatiyan or account number with different structures.
Recommended Free Tools
Chhattisgarh’s system, as described in the DoLR-supported study, assigns a khata number to a landowner or pattadar for lands of a similar type in a village; the account can show total extent spread across multiple survey numbers. Land type affects how the details are arranged. Do not carry that exact rule into another state without checking its revenue department’s definitions.
Gujarat provides a useful contrast. The Surat district government’s E-Dhara page lists separate services for “VF7 Survey No Details” and “VF8A Khata Details,” and explains that mutation updates land records after events such as sale, inheritance and distribution: Surat E-Dhara land records. The separate services are a warning that a khata lookup and a survey lookup answer different questions.
How the three identifiers relate
Think of the records as layers rather than competing numbers. A survey or plot reference generally locates a parcel in a local record and map system. A khata commonly groups one or more such parcel entries under a holder or account. A deed may contain all of them, plus boundaries and area, because the transaction needs to identify both the land and the parties.
| State example | What the official material shows | How to use the example |
|---|---|---|
| Chhattisgarh | Khasra is described as a village-wise survey-number record; khata can consolidate land across survey numbers for a pattadar, with land-type effects. | Use the survey entry to trace a parcel and the khata to inspect the associated holding. Confirm the exact current fields in the state portal. |
| Gujarat | E-Dhara lists VF7 survey-number details and VF8A khata details as separate services; mutation records update entries after transfers. | Run both relevant searches and verify that mutation and deed information agree. |
| Odisha | Bhulekh accepts Khatiyan number, plot number or tenant details; map viewing is provided separately. | Search with the available reference, then open the map instead of treating the search result as a boundary certificate. |
These are illustrations, not interchangeable definitions. Before interpreting a number, identify the state or Union territory, the issuing authority, the record type and whether the entry is current or a legacy reference.
Which number should you check before buying land?
Check every identifier that appears in the transaction documents, but give priority to consistency across four sources: the registered deed and prior title chain, the current RoR, the cadastral map and the mutation history. There is no reliable pan-India rule that one number outranks the others.
1. Read the sale deed and title chain
Start with the property schedule in the proposed sale deed and earlier title documents. Record the complete survey or plot reference, sub-number, khata or account number, village or locality, stated extent and all four boundaries. Compare the seller’s name and the chain of transfers, partitions, inheritances or releases. DoLR includes title-deed verification among the steps in land registration; its citizen-services explanation is at dolr.gov.in/en/citizen-centric-services/.
2. Obtain the current Record of Rights
Use the official revenue portal for the state or Union territory. Search with the identifier the portal accepts and download or save the current RoR, including its issue date and any digitally signed status. Check recorded holder names, area, land classification, tenancy or cultivation fields where shown, and references to transactions or encumbrances. State and UT revenue departments maintain RoRs and provide them through dedicated portals, but an online entry should still be checked against the deed and map.
3. Open the cadastral or survey map
Locate the parcel on the official map or obtain a certified map extract where the portal does not provide one. Compare the parcel shape, adjoining survey numbers, access road and boundary points with what you are being shown. Spatial records establish boundaries on the ground; a textual RoR cannot substitute for that spatial check.

4. Check mutation and transaction history
Look for entries after sale, inheritance, partition, gift, court order or other transfer. A mutation entry updates revenue records after an event; it is an important consistency check but should not be treated as a universal title guarantee. Gujarat’s E-Dhara description specifically lists sale, inheritance and distribution as events that can trigger mutation updates.
5. Check for old, revised or subdivided references
Ask the revenue office or portal whether the number has been resurveyed, renumbered or divided. Obtain the link between an old number in an earlier deed and the current number in the RoR. An unexplained change in digits, area or subdivision is a reason to pause, not an assumption that the records are equivalent.
6. Resolve discrepancies before paying
If the deed, RoR and map disagree on holder, area, boundaries or parcel identity, stop the transaction until the issue is documented. Engage a property lawyer familiar with that state’s revenue and registration practice. If the physical boundary is disputed or unclear, use a survey professional authorized in the relevant locality. The national guidance distinguishes title verification from spatial mapping but does not prescribe one remedy for every mismatch.
How to find a plot using a survey number
- Identify the jurisdiction. Note the state or Union territory, district, taluk or tehsil, village and the record year shown on the deed.
- Use the official land-record portal. Select the district and local unit, then choose the search field labelled survey, plot, khasra, dag, khatiyan or its local equivalent.
- Enter the complete reference. Include subdivision characters and leading zeros exactly as printed. Try the portal’s old-number or resurvey option if available.
- Read the returned record. Check holder, area, land type, account or khata reference, transaction notes and the record date.
- Open the map function. Select the parcel and compare its outline and neighbours with the land shown to you. If the portal separates text and map services, use both.
- Save an official copy. Keep the PDF, digitally signed extract or certified copy with the access date. Screenshots without identifying metadata are weak evidence.
- Cross-check the deed. Any difference in extent, boundaries or holder name should be explained in a registered document or official correction before completion.
Portal labels and menus change, so use the relevant state revenue department’s current instructions rather than assuming that a search field has the same meaning elsewhere.
ULPIN (Bhu-Aadhar): an additional parcel identifier
DoLR describes ULPIN, also called Bhu-Aadhar, as a 14-digit identification number generated from parcel longitude and latitude, detailed surveys and geo-referenced cadastral maps. The department’s current page says rollout has occurred in 29 States/UTs; that implementation figure is time-sensitive and should be checked on the live page: DoLR ULPIN information.
ULPIN can make it easier for participating systems to refer to the same geospatial parcel, but DoLR does not state that it has replaced every survey, plot or khata reference. If a portal displays a ULPIN, record it and ask how it links to the local parcel and RoR. Continue checking the local deed, map and mutation history.
Common buyer mistakes and how to avoid them
- Assuming identical labels: “Plot number” may be a layout reference while “survey number” is the underlying revenue reference. Obtain the official cross-reference.
- Treating khata as a parcel: A khata may cover several survey entries. Read the account’s individual parcel lines and total extent.
- Checking only the portal: An online result is not a substitute for the registered deed, title chain and cadastral map.
- Ignoring subdivisions: A main survey number can have multiple sub-numbers with different holders or areas. Match the complete notation.
- Using an old deed without a current link: Require evidence connecting legacy or resurvey numbers to the current record.
- Confusing mutation with title: Mutation records an update in revenue records; it does not by itself cure defects in the underlying title.
- Measuring instead of verifying: A tape, phone GPS reading or consumer mapping app may help you observe a site, but it does not identify an official record reference or establish ownership.
- Paying before resolving conflicts: Put discrepancies on hold and obtain state-specific legal and surveying advice before signing or transferring funds.
A practical document checklist
- Current sale deed draft with the complete property schedule.
- Earlier deeds and partition, inheritance, gift or release instruments in the title chain.
- Current RoR or equivalent record, with issue date and issuing authority.
- Cadastral or survey map showing the parcel and adjoining identifiers.
- Mutation orders and transaction history after each recorded transfer.
- Approved layout or conversion documents when a plotted development is involved.
- Any old-to-new survey or resurvey certificate.
- ULPIN, if the state portal provides one, together with its parcel link.
- Written explanations and professional opinions for unresolved differences.
What the numbers can—and cannot—tell you
A matching survey or plot number helps you locate the intended parcel. A matching khata entry helps connect that parcel to the relevant holding or account. A matching RoR provides recorded rights information, and a matching map checks the spatial identity. None of those elements, viewed alone, is a nationwide guarantee that the seller has marketable title, that there are no encumbrances, or that every boundary is error-free.
For perspective, the 2024–25 DoLR-supported Chhattisgarh study reports 5.17 million RoRs with mortgage mention or red-flag information and 4,743 banks linked to that state’s RoR database. Those are figures about Chhattisgarh’s system, not national measurements of identifier accuracy or buyer risk. They should not be used to infer that a particular property is clear or encumbered without checking its own record.
The Bottom Line
Before buying, identify what each number means in the relevant state, then reconcile the complete deed schedule, current RoR, mutation history and cadastral map. Treat ULPIN as an additional geospatial key where available—not as a replacement for local records—and obtain state-specific legal or surveying help whenever the documents and the land do not match.
