How to Verify a MahaRERA Project Registration Before You Book a Mumbai Flat
A buyer-side guide to checking a Mumbai project's MahaRERA registration, scanning the QR code, reading the completion date, progress and financial disclosures, and knowing what the record does and does not promise.
At a Sunday show flat in Chembur, a couple noticed something the sales manager did not draw attention to: a small QR code in the corner of the brochure. On a whim they scanned it, landed on the MahaRERA project page, and saw that the completion date on record was a full year later than the possession the manager had just promised them over coffee. Nothing about the project was fraudulent. But the QR code told the truth the pitch had softened, and that one scan reset their expectations before they paid a rupee.
The short answer. Every qualifying project in Mumbai must be registered with the Maharashtra Real Estate Regulatory Authority (MahaRERA), carry a registration number that usually begins with P518 or P519, and print a QR code on its advertising that links straight to the official record. You can verify any project yourself at maharera.maharashtra.gov.in by searching Registered Projects, or simply by scanning that QR code. The trade-off worth understanding: registration and its disclosures give you a documented, dated version of the project that you can hold the promoter to, but they do not guarantee on-time delivery, so you read the disclosures to judge risk, not to remove it.
What does MahaRERA registration actually give a Mumbai buyer?
MahaRERA registration gives you a public, promoter-signed record of the project against which you can measure every verbal promise. The Maharashtra Real Estate Regulatory Authority requires qualifying projects to register before they are advertised or sold, and the registration brings with it disclosures the promoter must keep updated: the approved completion date, quarterly construction progress, the approvals obtained, the number of flats in the project and how many have been sold, and financial statements certified by a chartered accountant. For a buyer, the value is that these are not marketing claims. They are filings, and a promoter who files one thing and tells you another has created a gap you can see.
What registration does not do is equally important to hold in mind. It is not a state guarantee that the building will finish on schedule or to a particular standard. Projects still slip, and disputes still happen. The registration exists so that when they do, you are dealing with a documented baseline and a specialised authority rather than only marketing brochures and a civil court. Treat the record as your risk-reading tool, not as a promise that nothing will go wrong. This is also why buyers who only glance at the status line miss the point. The status confirms the project is registered, but the risk lives in the details behind it: how recent the filings are, how the promised date compares with reality, and whether the money side has been kept up. Reading those takes a few extra minutes and is where verification actually earns its keep.
How do I find and read a project on the MahaRERA portal?
You find it on the official portal at maharera.maharashtra.gov.in, under the Registered Projects search. You can look up a project by its name, by the promoter's name, by district, or most reliably by the MahaRERA registration number itself. Searching by the number is the surest route, because marketing names change and a slightly wrong project name returns nothing, while the number maps to exactly one record. If a brochure quotes a number and the portal shows no match, treat that as a reason to stop and ask, not a typing slip to shrug off.
The fastest path of all is the QR code. MahaRERA requires promoters to display a project QR code on advertisements, and scanning it takes you directly to that project's official page. Once you are on the record, do not stop at the status line. Open the disclosures, read the completion date, and check when the quarterly progress was last updated, because a registered project that has gone quiet on its filings is telling you something. We walked through reading these screens in detail in our earlier guide to verifying a Mumbai project on MahaRERA and reading its disclosures.
What is that P518 number, and where must it appear?
The MahaRERA registration number is the project's unique identity, and for Mumbai projects it typically begins with P518 or P519. The leading P stands for project, followed by the state and region coding and a unique number, so no two projects share one. MahaRERA requires this number to be quoted on the project's advertisements, booking forms and the sale agreement, which means you should be able to find the same number in every document you are handed. When the number on the hoarding, the number on the booking form and the number on the draft agreement all match the portal record, you have a consistent paper trail.
Inconsistency is the warning sign here. If the brochure carries one number and the agreement another, or a salesperson is reluctant to put the registration number in writing, that friction is worth taking seriously. The number is not a formality; it is the thread that ties the marketing to the legal record, and it should run unbroken from the advertisement to the agreement you finally sign.
Which disclosures should you actually read?
Registration is only useful if you open what sits behind it. These are the disclosures that most often change a buyer's decision, and the red flag to watch for in each.
| Disclosure on the record | What it tells you | Red flag to watch |
|---|---|---|
| Registration status | Whether the project is live and valid | Marked lapsed, withdrawn or expired |
| Registered completion date | The handover the promoter committed to | Far later than the sales team's verbal date |
| Quarterly progress updates | Actual construction and status filed by the promoter | Not updated for several quarters |
| Flats sold and inventory | How much of the project is already booked | Portal numbers clash with the sales pitch |
| CA-certified financials | Money raised and spent on the project | Missing, sparse or clearly irregular |
Read across the row rather than down a single column. A project can have a valid status yet stale progress, or a fine completion date yet financials that do not add up. It is the combination that tells you how much confidence the record actually supports.
What is your verification checklist before booking?
Run this sequence before you pay a booking amount, and keep a dated copy of what you find. It takes minutes and it is the cheapest protection in the entire purchase.
- Scan the QR code on the advertisement or brochure and confirm it opens an official MahaRERA page.
- Separately search the registration number at maharera.maharashtra.gov.in and confirm it matches.
- Check the registration status reads as registered or renewed, not lapsed or withdrawn.
- Compare the registered completion date with the possession date you are being promised.
- Open the quarterly progress and confirm the filings are recent, not stale.
- Confirm the same registration number appears on the booking form and the draft agreement.
- Save screenshots of the record, dated, before you transfer any money.
What extra checks matter for Mumbai redevelopment projects?
Many Mumbai flats are sold in redevelopment projects, and here the MahaRERA record is only part of the story. In a redevelopment, existing society members are being rehoused while new flats are sold to fund the scheme, so a buyer wants to see that the project is registered, that the promoter's obligations to existing members are on record, and that approvals are genuinely in place rather than merely applied for. The registered completion date matters even more, because delays in a redevelopment ripple through both the existing residents and the new buyers. If you are buying a resale flat in a completed society instead, the paperwork shifts toward the society itself, which we covered in our guide to the society share certificate and NOC for a Mumbai resale flat. Whichever route you take, the discipline is the same: confirm the registration, read the disclosures, and make sure the documents you are handed all point to the same record before you commit. A registered project with clean, current filings is not a promise of a perfect outcome, but it is a far better place to start than a glossy brochure with a number no one wants to write down. It also helps to remember that in a hot market the pressure to book quickly is exactly when this discipline matters most, because a rushed booking is the one made before the record is read. Slowing down for ten minutes to check the portal is never the expensive mistake; skipping it can be.
Frequently asked questions
What does a Mumbai MahaRERA registration number look like?
For Mumbai projects the MahaRERA registration number usually begins with P518 or P519, where the leading P stands for project, followed by region coding and a unique number. That number must be quoted on the project's advertisements, booking forms and sale agreement, so you should be able to find the same number in every document and match it against the record on maharera.maharashtra.gov.in.
Can I trust the QR code on a builder's advertisement?
The QR code is a genuine verification tool because MahaRERA requires promoters to display it on advertising, and scanning it should take you to the project's official page. Still, treat it as a starting point. After scanning, separately search the registration number on the portal, confirm the details match, and read the disclosures before you rely on it.
Does MahaRERA registration guarantee my flat will be delivered on time?
No. Registration gives you a documented, dated record with disclosures the promoter must file, and a specialised authority to approach if things go wrong, but it is not a state guarantee of timely delivery or build quality. Projects can still be delayed. You use the record to judge risk, by reading the completion date, the quarterly progress and the financials, not to remove it.
What should I do if the numbers on the documents do not match?
Stop and resolve it before paying. If the registration number on the brochure differs from the one on the booking form or draft agreement, or a salesperson will not put the number in writing, that inconsistency is a real warning. The same number should run from advertisement to agreement and match the portal record.
