What a registration number is, and is not
The Real Estate (Regulation and Development) Act, 2016 requires a promoter to register a project with the state regulator before advertising or selling it. In Karnataka that regulator publishes every registration on its own portal, along with the documents the promoter filed.
So a registration number is an index key. It is the thing you type into the portal to pull up the promoter's own declarations. That is its entire value to you as a buyer.
What it is not:
- It is not a quality rating. Nobody inspected the concrete to issue it.
- It is not a guarantee of possession on the declared date.
- It is not a statement that the title is clean. It means title documents were filed, not that they were adjudicated in your favour.
- It is not transferable between phases or between projects by the same promoter.
Treat it the way you would treat a company registration number. Useful, verifiable, and silent on whether the business is any good.
Reading the segments of the number
A Karnataka registration number is a string of segments separated by slashes rather than a single code. One of the registrations published on this site reads:
PRM/KA/RERA/1251/446/PR/051024/007125
Read left to right, the segments line up as the registration type, the state, the Act, the division and office codes, a marker for a project registration, a date, and a running serial number. In that example the date segment reads as 5 October 2024 and the serial is 007125.
Segment formats are set by the regulator and can change. If a segment does not parse the way you expect, do not guess at it and do not assume the number is fake. Search the full string on the portal instead. The portal record is the authority on what the number means.
One practical use for the reading: serial numbers climb over time. If you hold two registrations from the same promoter, the one with the higher serial is normally the later registration. That is a quick sanity check on which phase came first, and nothing more.
The seven checks, in order
Do these in sequence. Each one is cheap, and the order is designed so a problem surfaces before you have spent anything.
-
Get the number in writing, for your specific phase
Ask the sales team for the registration number of the phase and tower you are being sold, by email or on letterhead. Not the project's first phase, not a number from a brochure photograph. If a project has four phases, there is a right answer and three wrong ones.
-
Search it on the Karnataka RERA portal
Go to rera.karnataka.gov.in and search the project by the full registration number, slashes included. If the portal returns nothing, try searching by promoter name and project name before concluding anything, because a typo in one character returns an empty result just as a fabricated number does.
-
Confirm the project name and the promoter name
Both should match the agreement you are about to sign. A common and legitimate surprise is that the registered promoter is a special purpose company or a joint venture entity rather than the brand name on the hoarding. That is normal. What matters is that the entity on the portal is the entity named in your agreement for sale.
-
Check the registered start and end dates
The end date is the completion date the promoter declared to the regulator. Compare it with the possession date the sales team quoted you and with the date in the draft agreement. These three should be the same date. If they are not, ask for the difference in writing.
-
Open the approved plan and the project details
Check the land area, the number of towers, the number of units, and the approved plan against what you were shown in the sales lounge. Then check that the amenities you are buying into appear in the registered scope. A clubhouse that exists only in a brochure render is a different thing from a clubhouse in an approved plan.
-
Read the latest Quarterly Progress Report
This is the page most buyers skip and the one worth the most. The QPR is filed by the promoter every quarter and covers construction progress, approvals received, and units booked. Read the last two or three, not just the most recent, because the useful signal is the trend. Slabs cast per quarter tells you more about a 2029 possession date than any projection does.
-
Repeat for every other phase you care about
If the clubhouse, the sports courts or the access road sit in a different phase from your tower, that phase has its own registration, its own completion date and its own progress reports. Your flat can be ready on time while the amenity you bought it for is two years behind.
Why one project can have several numbers
Large developments are registered in phases, so a single marketing name can sit on top of several registrations. Two examples from the projects on this site:
| Project | Phases | What that means for you |
|---|---|---|
| Sumadhura Folium | 4, each registered separately | Four completion dates and four sets of progress reports. Check the phase your tower is in. |
| Sumadhura Panorama | 2, each registered separately | 539 plots across two phases. Phase 1 is open now, so confirm which phase your plot sits in. |
Phase counts are as published by the developer. Confirm the registration for your specific unit with the project team.
Mismatches that should stop a booking
None of these means fraud. All of them mean get an answer in writing first.
| What you find | Why it matters | What to ask |
|---|---|---|
| Portal returns no result for the number | The number may be mistyped, or the phase may not be registered yet | For the number again in writing, and for the registration certificate PDF |
| Possession date on the portal is later than the one you were quoted | The declared date is the one with legal weight | Which date goes into the agreement for sale |
| Promoter entity differs from the brand name | Usually legitimate, but your contract is with the entity | That the agreement names the same entity as the portal |
| Unit count or land area differs from the sales pitch | Density and open space change with unit count | For the approved plan showing the current count |
| No Quarterly Progress Report for the last two quarters | Filings are a compliance obligation | Why filings are behind, and for the latest construction photographs |
| Amenity you are buying for is absent from the registered scope | Brochure renders are not commitments | Where that amenity appears in the approved plan |

A worked example: five registered projects
Every project on this site publishes its registration number, so you can run the seven checks above against them right now rather than practising on a hypothetical. Each number below is also printed in the footer of every page.
| Project | Where | Registration | Declared possession |
|---|---|---|---|
| Capitol Residences | Hope Farm Junction, Whitefield | PRM/KA/RERA/1251/446/PR/051024/007125 | December 2027 |
| Edition | Siddapura, Whitefield | PRM/KA/RERA/1251/446/PR/111225/008328 | December 2029 |
| Solace | Thubarahalli, Marathahalli Main Road | PRM/KA/RERA/1251/446/PR/111225/008330 | December 2029, as per RERA |
| Folium | Near Palm Meadows, Whitefield | Four phase registrations, see the footer | March 2028 |
| Panorama | Devanahalli, on NH 44 | Two phase registrations, see the footer | Phase 1 open now |
Registrations and possession dates are as published by the developer and reproduced here for verification. Search each number on rera.karnataka.gov.in for the authoritative record.
Notice that Edition and Solace share a date segment and sit one serial apart. Two registrations filed the same day by the same promoter is exactly what you would expect for two projects launched together, and it is the kind of small consistency check the portal lets you make in a minute.
What RERA gives you after you book
Verification is not only a pre-booking exercise. Once you are a buyer, the same framework keeps working for you:
- A dated completion commitment. The declared date in the registration is the reference point for any delay discussion.
- Quarterly disclosure. You can track your own project's progress filings without asking anyone for a favour.
- A defined carpet area. RERA requires carpet area to be the basis of sale, which is why you should always read the carpet number rather than a super built up number.
- A complaints route. Disputes go to the state authority rather than only to a civil court.
Set a reminder to read your project's QPR once a quarter. It takes five minutes and it is the cheapest project monitoring you will ever do.
This is a general explanation of a public verification process, written for buyers. It is not legal advice and it is not a substitute for a property lawyer reading your specific title documents and agreement for sale. Engage one before you sign.
Where do I check a RERA number in Karnataka?
On the Karnataka RERA portal at rera.karnataka.gov.in. Use the project search and paste the full registration number, including the slashes. The portal is the authoritative record. A number printed on a brochure, hoarding or website is only a claim until the portal confirms it.
Does a RERA registration mean the project is approved or safe?
No. Registration means the promoter has disclosed the project to the regulator and filed the required documents, and that the project is now subject to RERA obligations. It is not a quality certificate, a guarantee of delivery, or an endorsement. The disclosures are what help you, not the registration itself.
Why does one project have more than one RERA number?
Because phases are registered separately. A project launched in four phases will usually carry four registration numbers, each with its own declared completion date and its own quarterly progress reports. Always check the registration for the phase and tower your flat sits in.
What is a Quarterly Progress Report and why does it matter?
The QPR is a filing the promoter submits every quarter covering construction progress, approvals received, and units booked. It matters because it is self-reported, dated, and sits in the public record, so you can compare what was promised last quarter against what was filed this quarter.
What happens if the possession date on the portal is later than the one I was told?
The date in the registration is the one that carries legal weight, because it is the date declared to the regulator. Ask for the difference in writing before you book, and check that the agreement for sale carries the same date as the portal.
Can I check a plotted development the same way?
Yes. Plotted developments are registered too, and they are also registered phase by phase. For a plotted project, pay particular attention to the approved layout plan and to which amenities are inside the registered scope.
