ULPIN (Bhu-Aadhaar): What the 14-Digit Land ID Means for Owners
ULPIN (Bhu-Aadhaar) is a 14-digit ID for a land parcel, generated from its map coordinates. It identifies the land; it does not prove ownership.

ULPIN, or Bhu-Aadhaar, is a 14-digit alphanumeric ID given to a single land parcel. The state revenue department generates it from the latitude and longitude of the parcel’s corner points on a georeferenced map. It identifies the land, not the owner, and it does not by itself prove who owns the plot.
Key facts
| Item | Detail |
|---|---|
| Full name | Unique Land Parcel Identification Number (ULPIN), also called Bhu-Aadhaar |
| Format | 14 characters, letters and digits |
| Based on | Georeferenced latitude and longitude of the parcel’s vertices |
| Standards | ECCMA and Open Geospatial Consortium (OGC) |
| Generated by | State or UT revenue administration, using a DoLR software utility |
| Programme | Digital India Land Records Modernization Programme (DILRMP), Department of Land Resources |
| Parcels covered | Over 40.58 crore, as reported by DoLR on 27 August 2026 |
What ULPIN is
Most land records in India identify a plot by a local number: a khasra, survey or dag number that is unique only within one village. The same number can exist in thousands of villages. ULPIN gives each parcel one national ID instead, so any system that knows the number can find the exact piece of land.
The Department of Land Resources (DoLR) calls it a single, authoritative source of truth for a land parcel. It sits inside DILRMP, the central programme that has computerised records of rights and digitised village maps across states. The Union Budget 2024-25 listed Bhu-Aadhaar for all rural land among the land reforms states would be encouraged to finish.
The “Aadhaar” in the name is a comparison, nothing more. ULPIN is a number for the land and is generated from map coordinates, not from anyone’s identity.
How the number is generated
ULPIN depends on the village cadastral map being digitised and georeferenced, so that every plot boundary has real-world coordinates. The process DoLR describes is:
- The state digitises the village map and ties it to ground coordinates.
- Each corner (vertex) of the parcel gets a latitude and longitude.
- Software supplied by DoLR applies a formula to those vertex coordinates.
- The result is a 14-character ID in the ECCMA “Property Natural Identifier” format, stored against the parcel in the state’s land records database.
DoLR developed the system with the Department of Science and Technology and the National Informatics Centre. Its FAQ says the ID does not depend on state, district, tehsil or village codes. Some websites describe the 14 characters as a string of administrative codes; DoLR’s own description does not support that.
When the ULPIN changes
| Event | Does the ULPIN change? |
|---|---|
| You sell the whole parcel | No. The boundary and coordinates stay the same. |
| The parcel is partitioned or subdivided | Yes. New parcels get new IDs. |
| Any other change to the parcel’s shape | Yes. The old ID is archived for reference. |
So the number follows the land’s geometry, not its ownership.
Where to find your parcel’s ULPIN
There is no national lookup for citizens. DoLR says whether ULPINs are made public is up to each state or UT revenue department. Where a state shows them, they usually appear on its land records portal next to the plot details.
- Maharashtra: the Mahabhumi “Know your Jurisdiction” page lets you search a ULPIN by 7/12 survey number or property card (CTS) number, or enter a ULPIN to find the plot. See our Maha Bhulekh guide for the 7/12 extract itself.
- Other states: open your state’s record of rights or bhu naksha service and look for a ULPIN or Bhu-Aadhaar field. If it is not shown, ask the tehsil or revenue office.
A missing ULPIN usually means the village map has not yet been georeferenced. DoLR reported that 76.16% of land parcels were fully georeferenced as of August 2026.
How it helps buyers and banks
| Item | Details |
|---|---|
| One reference across records. | The same ID can link the map, the record of rights, registration data and revenue court cases, so a check in one system points to the right parcel in the others. |
| Fewer look-alike errors. | A buyer or lender is less likely to confuse two plots that share a khasra number in different villages. |
| Boundary clarity. | Because the ID comes from coordinates, it ties the paper record to a mapped shape. DoLR says this can reduce boundary disputes. |
| Scheme targeting. | Governments can use it to decide entitlements that depend on how much land a person holds. |
Treat ULPIN as one item on your checklist, not a substitute for it. You still need the title chain, encumbrance search and mutation status; our property legal due diligence checklist lists them.
Link to DILRMP and the Land Stack
On 10 September 2026, the Rural Development Minister launched the operational guidelines for DILRMP 3.0, which runs from 2026 to 2031. PIB announced an anticipated outlay of ₹565.50 crore, with 100% central funding. “Universal Bhu-Aadhaar”, a ULPIN for every parcel in the country, is one of its components. Others include:
- A GIS-based Land Stack in each state that joins maps, records of rights, registrations and court matters.
- A registration repository of registered deeds and encumbrance information.
- Modernising 75 high-footfall Sub-Registrar Offices into Registration Seva Kendras.
- Paperless revenue courts linked to land records, and the NAKSHA urban mapping pilot.
DoLR’s August 2026 figures show how far the base layer has come: 99.90% of records of rights computerised, 97.43% of cadastral maps digitised and 85.24% of maps linked to the text records.
What ULPIN does not change
| Item | Details |
|---|---|
| Ownership rules. | Title still comes from registered documents and inheritance. Records of rights are still updated by mutation at the revenue office. |
| Your local numbers. | Khasra, survey, khata and plot numbers stay in use; the ULPIN sits alongside them. |
| Existing errors. | If the digitised map or the record of rights is wrong, the ULPIN will point to the wrong shape or owner. Correct the underlying record through the revenue office. |
| Taxes and fees. | Stamp duty, registration charges and land revenue are set by each state and are unaffected. Our property registration guide covers those steps. |
For a disputed or inherited parcel, a local property lawyer can check the full record before you buy or lend against it.
Frequently asked questions
What is the full form of ULPIN?
Unique Land Parcel Identification Number. It is also called Bhu-Aadhaar.
How many digits does a Bhu-Aadhaar number have?
14 characters. It is alphanumeric, so it mixes letters and digits.
Is Bhu-Aadhaar linked to my Aadhaar card?
ULPIN is generated from the parcel’s map coordinates, not from the owner’s identity. Any link between land records and owners’ Aadhaar is a separate matter handled by each state.
Does the ULPIN change when I sell my land?
No, not if you sell the whole parcel. It changes only when the parcel’s shape changes, such as on partition.
How can I check the ULPIN of my land?
Check your state’s land records portal; Maharashtra, for example, lets you search by 7/12 survey number. If your state does not display it, ask the tehsil or revenue office.
Does ULPIN prove ownership?
No. It identifies the parcel. Ownership still rests on registered documents and the record of rights.
How many land parcels have a ULPIN?
Over 40.58 crore, according to figures DoLR shared in August 2026.
