Quick answer: ULPIN (Unique Land Parcel Identification Number), popularly called Bhu-Aadhaar, is a 14-character alphanumeric ID that the government assigns to a land parcel after its boundary has been geo-referenced on a digital map. It identifies the land, not the owner. You do not apply for it — your state revenue department generates it, and it appears on your digital record of rights (khatauni, 7/12, RTC, jamabandi, khatiyan, pahani). As of August 2026, more than 40 crore land parcels had received a ULPIN, and the new DILRMP 3.0 (2026–2031) aims to give one to every parcel in India.

ULPIN at a glance (October 2026)

What changed in 2026

If you read about ULPIN before this year, much of it is now out of date. Here is what actually moved:

• February 2026 – Delhi switches to mission mode. The Delhi government decided to give every parcel in the capital a ULPIN, with the Revenue Department’s IT branch implementing it and the Survey of India supporting. A pilot in Tilangpur Kotla village (West Delhi) generated 274 ULPINs.
• 7 February 2026 – Maharashtra measures subdivisions. Maharashtra began a statewide exercise to measure agricultural sub-divisions so that each actual holding can get its own Bhu-Aadhaar. This matters because a parcel that exists on paper as “45/2” but was never measured cannot get a geo-referenced ID.
• August 2026 – 40 crore mark crossed. DoLR reported more than 40.58 crore parcels with a ULPIN, up from about 36 crore in November 2025 and roughly 8.4 crore in October 2024.
• 10 September 2026 – DILRMP 3.0 launched. Union Rural Development Minister Shivraj Singh Chouhan released the operational guidelines. The new phase moves from “digitise each record” to a connected, GIS-based Land Stack, with Universal Bhu-Aadhaar as its anchor (details below).
• 1 October 2026 – Maharashtra makes Aadhaar authentication mandatory for property registration. Note the difference: this is the person’s 12-digit Aadhaar, used to stop impersonation at the sub-registrar office. It is not the land’s Bhu-Aadhaar. Many news readers confused the two.

How a ULPIN is actually created

A ULPIN is not handed out like a serial number. It comes at the end of a chain, and if any link is missing, your plot will not have one yet:

1. Textual record digitised – the record of rights (owner, area, khasra/survey number) is computerised. Nationally, 99.9% of RoRs are now digital.
2. Cadastral map digitised – the village map is scanned and vectorised. About 97% of cadastral maps are digitised.
3. Map geo-referenced – the digital map is pinned to real-world coordinates using satellite imagery, drones or ground survey. DoLR describes geo-referencing as a pre-condition for generating Bhu-Aadhaar.
4. Record linked to map – each khasra/survey number in the RoR is matched with its polygon on the map. Mismatches (area on paper differs from area on map) are where most delays happen.
5. ULPIN generated – software computes the ID from the latitude/longitude of the parcel’s boundary vertices, following ECCMA and OGC standards, and writes it back into the RoR.

Andhra Pradesh’s earlier “Bhudhaar” project, which inspired ULPIN, used a two-step model: a temporary number based on the text record, later converted into a permanent one once geo-coordinates were added. Several states follow a similar sequence, which is why some records show an ID that later changes.

Can you decode a ULPIN? (Why we don’t publish a “digit table”)

Many websites show a neat table claiming the 14 digits break down as state (2) + district (2) + sub-district (3) + village (3) + plot (4). That is not how DoLR’s own ULPIN concept note describes it. The note says the core ID is computed from the latitude/longitude of the parcel’s vertices under the ECCMA standard, and that the number shown to the public may be mapped to a random number carrying only a state-code prefix. In other words, apart from a possible state prefix, the characters are not a readable address. Treat any “ULPIN decoder” with suspicion — the only reliable way to know what a ULPIN points to is to search it on the official state portal.

The life of a ULPIN: what happens when the land changes

Because a ULPIN is tied to a boundary on the map, the simple rule is: if the boundary stays the same, the ULPIN stays the same; if the boundary changes, new parcels need new IDs. State practice varies, so confirm with your tehsil/circle office, but this is how it generally works:

You will often read that a ULPIN “never changes, even after sub-division”. It does stay with the land through a sale or inheritance of the whole plot. But DoLR’s concept note says the system generates a new ID when a mutation changes the parcel’s coordinates — and a newly measured share is exactly that. It is also why Maharashtra decided in February 2026 to measure the 2.12 crore sub-divisions created since 1992 before linking them to Bhu-Aadhaar. How your state links the old (parent) and new (child) numbers depends on its software, so ask your tehsil how a partition will be recorded.

8 myths about Bhu-Aadhaar, corrected

ULPIN vs the other numbers on your land papers

How to find your ULPIN, step by step

1. Open your state’s official land-records portal from the list above (only .gov.in or .nic.in addresses).
2. Select district, tehsil/taluka/circle and village.
3. Search by khasra, survey, gata, khata or owner name. Some portals also offer a direct ID search: MP Bhulekh accepts a ULPIN, and UP Bhulekh accepts the state’s 16-digit “Unique Code” (see the FAQ below for how that differs from a ULPIN).
4. Open the record (khatauni, 7/12, RTC, jamabandi, khatiyan, pahani). Look for a field labelled ULPIN, Bhu-Aadhaar, Unique Code or Parcel ID.
5. Open the Bhu-Naksha (map) for the same plot and confirm that the shape and area match what you see on the ground.
6. Save a digitally signed copy if your state offers one — that is the version banks and courts accept.

Your plot has no ULPIN — what now?

• Check the neighbouring plots. If none of them have a ULPIN either, your village simply hasn’t been geo-referenced yet. Nothing for you to do except keep records updated.
• If neighbours have one and you don’t, the most common causes are a pending mutation, a sub-division that was never measured, or an area mismatch between the RoR and the map. Visit the tehsil/circle office with your deed and the latest RoR.
• If details are wrong (name, area, plot shape), apply for correction through the state’s grievance or correction module; Telangana’s Bhu Bharati, for example, has formal correction and appeal routes.

Using ULPIN to buy land safely: a 9-point checklist

1. Get the ULPIN from the seller and search it yourself on the state portal — never rely on a screenshot.
2. Confirm the owner name, area and land type on the RoR match the draft sale deed.
3. Open the Bhu-Naksha and compare the plot shape with the physical site and fencing.
4. If you are buying part of a parcel, insist on a measured sub-division first; otherwise your share has no ID of its own.
5. Pull the encumbrance certificate (EC) for at least 30 years to see mortgages and earlier sales.
6. Check pending revenue court cases (RCCMS, where your state has it online) and civil court records.
7. Check mutation history: frequent recent transfers deserve questions.
8. Make sure the sale deed mentions the ULPIN along with the khasra/survey number.
9. After registration, apply for mutation and confirm the new RoR shows your name against the same ULPIN.

A ULPIN makes it far harder for one plot to be passed off as another, but it is a locator, not a clearance. Title due diligence is still needed.

DILRMP 3.0 (2026–2031): where ULPIN goes next

The third phase of the Digital India Land Records Modernization Programme is a Central Sector Scheme, fully funded by the Centre, with an outlay of ₹565.50 crore from April 2026 to March 2031. Its key pieces:

• Universal Bhu-Aadhaar – a ULPIN for every parcel: rural, semi-urban and urban.
• Land Stack – each state links land records, maps, registration and court data through APIs, so one ULPIN can pull related information across departments instead of copies being kept in silos.
• Registration Seva Kendras – 75 high-footfall sub-registrar offices upgraded on the Passport Seva Kendra model.
• RCCMS – revenue court case management integrated with land records, so a plot’s dispute status sits next to its record.
• NAKSHA acceleration – GIS-based urban land records and Urban Property Cards (UrPro cards).
• Legacy record scanning and a registration repository, with funds released in phases based on performance, tracked on the DILRMP-MIS dashboard.

The earlier phases computerised 99.9% of records of rights, 97% of cadastral maps and 99% of sub-registrar offices, according to the government. DILRMP 3.0 is about connecting those pieces — and ULPIN is the key that connects them.

ULPIN in cities: NAKSHA

Urban land was the biggest gap. NAKSHA (National Geospatial Knowledge-based Land Survey of Urban Habitations) was launched on 18 February 2025 as a pilot in 152 urban local bodies across 26 states and 3 Union Territories, with Survey of India providing aerial imagery. Under DILRMP 3.0 it is being expanded to issue Urban Property Cards, bringing city plots into the same parcel-ID system.

How we got here: ULPIN timeline

Why do the percentages look inconsistent across reports? The total number of “listed parcels” keeps rising as states record sub-divisions, and some reports count only rural parcels while others count everything. Compare like with like.

ULPIN क्या है? (हिंदी में सार)

ULPIN यानी यूनिक लैंड पार्सल आइडेंटिफिकेशन नंबर, जिसे भू-आधार कहा जाता है, जमीन के हर टुकड़े (पार्सल) का 14 अंकों/अक्षरों का एक विशिष्ट नंबर है। यह जमीन की सीमा के कोनों के अक्षांश-देशांतर (latitude-longitude) से बनता है। यह जमीन की पहचान है, मालिक की नहीं — इसका आपके 12 अंकों वाले आधार कार्ड से कोई संबंध नहीं है।

• आवेदन नहीं करना होता: गांव का नक्शा डिजिटल और जियो-रेफरेंस्ड होने पर राज्य का राजस्व विभाग खुद नंबर बनाता है।
• कहां देखें: अपने राज्य के भूलेख पोर्टल पर खतौनी / खसरा / जमाबंदी / खतियान / 7/12 में “ULPIN”, “यूनिक कोड” या “भू-आधार” वाला कॉलम देखें।
• स्वामित्व का सबूत नहीं: मालिकाना हक रजिस्टर्ड बैनामा और दाखिल-खारिज (म्यूटेशन) से ही तय होता है।
• बंटवारे पर: जमीन बंटने पर नए हिस्सों की नपाई होती है और हर हिस्से को अलग ULPIN मिलता है।
• 2026 की स्थिति: अगस्त 2026 तक 40 करोड़ से अधिक पार्सलों को ULPIN मिल चुका है; DILRMP 3.0 (2026–2031) के तहत हर पार्सल को भू-आधार देने का लक्ष्य है।

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 ULPIN have?

14 characters. It is alphanumeric, so it can contain both letters and digits.

How do I apply for Bhu-Aadhaar online?

You can’t, and you don’t need to. The state generates the ULPIN once your village’s map is geo-referenced and your record is linked to it. If neighbouring plots have a ULPIN and yours doesn’t, visit your tehsil or circle office.

How can I check my ULPIN number?

Search your plot on your state’s official land-records portal by khasra, survey or khata number and look for the ULPIN / Unique Code field on the record. Use the state portal list on this page.

Is Bhu-Aadhaar the same as my Aadhaar card?

No. Aadhaar is a 12-digit number for a person issued by UIDAI. Bhu-Aadhaar (ULPIN) is a 14-character number for a land parcel.

Does a ULPIN prove ownership?

No. It identifies the parcel and links its records. Ownership is shown by the registered deed, mutation and record of rights.

Will my ULPIN change if I sell my land?

Not if you sell the whole parcel — only the owner details change after mutation. If the land is divided, the new pieces get their own IDs after they are measured.

Is ULPIN mandatory for property registration?

There is no single nationwide rule. Some states print or require the ULPIN in registration and land records; check your state’s registration department. Separately, many states now require the parties’ personal Aadhaar authentication at registration — that is a different requirement.

What is ULPIN in 7/12?

In Maharashtra, the 7/12 (Satbara) extract is the record of rights for agricultural land. Where a ULPIN has been generated, it appears on the 7/12 so the survey/gat number is linked to its geo-referenced parcel.

What is the Unique Code in UP Bhulekh khatauni?

Uttar Pradesh introduced its own 16-digit Unique Property Identification Code (UPIC) for every gata in 2018-19 — 6 digits of census village code, 4 of gata number, 4 of sub-division and 2 of land type. It is numeric and not geo-referenced, so it is not the same as the 14-character ULPIN, which UP is also generating. Count the digits to tell them apart. Full UP guide.

Is there a fee for ULPIN?

No fee is charged for the ULPIN itself. Your state may charge a small fee for a certified copy of the record.

Which ministry implements ULPIN?

The Department of Land Resources under the Ministry of Rural Development, through state and UT revenue departments. The technology was developed by the National Informatics Centre.

Does ULPIN cover urban property and flats?

ULPIN identifies land parcels. Urban plots are being mapped under NAKSHA and DILRMP 3.0, which also plans Urban Property Cards. How individual flats in a building are recorded depends on state systems.

Is my data safe if I search my land record?

Use only official .gov.in or .nic.in portals. Land records are public documents, but never share your personal Aadhaar, OTPs or bank details with third-party “Bhu-Aadhaar” websites or agents.
