How to Verify a MahaRERA Project Registration: A Mumbai Buyer's Guide

In mid 2026 a buyer in Thane was shown a glossy brochure for an under construction tower, complete with a MahaRERA registration number printed in the corner. It looked official, so he nearly paid his booking amount on the spot. On a hunch he typed that number into the MahaRERA portal that evening. The project existed, but the promoter name on the portal did not match the company collecting his cheque, and the declared completion date had already passed. A two minute search had just saved him from a deal built on a borrowed registration.

The short answer. Every sizeable real estate project in Maharashtra must be registered with MahaRERA before it can be advertised or sold, and you can verify any registration free on the official MahaRERA portal in a couple of minutes. The trade off is effort against risk: the check takes almost no time, yet skipping it leaves you trusting a number on a brochure that could be expired, mismatched or simply borrowed from another project. Verifying before you pay is the single cheapest protection a Mumbai buyer has.

Why does a MahaRERA registration matter?

A MahaRERA registration matters because it is the legal gateway that lets a developer sell a project at all, and it puts a body of verified information about that project on the public record. The Real Estate (Regulation and Development) Act created state authorities such as MahaRERA to bring transparency to a market long plagued by delays and diverted funds. When a project is registered, its key facts, the promoter, the approvals, the declared timeline and the land details, are filed with the regulator and made visible to any buyer who looks.

For you, the registration is both a permission and a disclosure. It signals that the project has entered the regulated system, and it gives you a reliable place to check the claims a salesperson makes. An unregistered project that is required to be registered is a serious warning, because it means the developer is operating outside the very framework designed to protect your money. The portal turns a leap of faith into a checkable fact. It also matters because registration carries obligations that continue after you book, such as the promoter keeping a defined share of buyer money in a dedicated account and filing regular progress updates, so a registered project is one the law keeps watching rather than one it merely waved through at launch.

Which projects must be registered with MahaRERA?

Under the Real Estate (Regulation and Development) Act, a project must be registered if the land proposed to be developed exceeds 500 square metres or if it has more than eight apartments, inclusive of all phases. Below that threshold registration is not mandatory, but the vast majority of apartment projects a Mumbai buyer will consider sit comfortably above it. The Act also makes clear that a promoter cannot advertise, market, book, sell or offer to sell any plot or apartment in such a project without first registering it.

This is why the presence or absence of a registration is not a formality you can wave away. If a developer is marketing a large project with no MahaRERA number, they are doing something the law forbids. If they quote a number, that number must stand up to scrutiny on the portal. Either way, the threshold tells you whether registration is required, and the portal tells you whether it is genuine. Note too that each phase of a large township is generally registered as its own project, so the number that matters is the one for the specific phase and building you are buying into, not a parent name the marketing uses to describe the whole development.

How do I find a project on the MahaRERA portal?

Finding a project is straightforward and needs no account or login. Go to the official MahaRERA portal and open the section for searching registered projects, then enter the registration number the developer has given you. If you do not have the number, you can also search by the project name, the promoter's name or the location to locate it. The portal returns the registered project page, which is the authoritative record you should read rather than the brochure.

Once the project page opens, slow down and read it properly rather than just confirming the project exists. The page carries the promoter details, the registration status and validity, the declared completion date, the quarterly progress updates the promoter is required to file, and any complaints or orders associated with the project. Treat this page as your source of truth, and treat any claim that contradicts it as suspect. If you are also budgeting the purchase, our guide to Mumbai stamp duty and registration charges covers the costs that follow once you are satisfied the project is clean.

What should I check on the project page?

Not every field on the registered page carries equal weight for a buyer, so it helps to know what to look at first. The table below lists the checks that matter most and why.

If any one of these fails, pause the deal and ask questions before you ask for your chequebook. A mismatch on the promoter name or an expired registration is not a paperwork quibble, it goes to whether the person taking your money has the right to sell you this home at all. Keep a dated screenshot of the project page as you saw it, because it is useful evidence if the project as delivered later departs from what the promoter declared on the record.

What do the registration number and QR code tell you?

The registration number is the unique identity of the project on the MahaRERA system, and in Maharashtra it typically takes a form beginning with the letter P for a project or L for a layout, followed by a string of digits. The single most important test is simple: the number printed on the brochure, the hoarding and the agreement must match the number on the portal exactly. A forged or misquoted number is an instant disqualification, because it means the paperwork and the regulator's record do not agree.

More recently, MahaRERA has pushed developers to display a QR code alongside the registration number in their advertising, and where such a code is present you can scan it to open the project's page on the portal directly. Used this way, the QR code is a convenient shortcut to the same authoritative record. Because the exact advertising rules are updated from time to time, confirm the current requirements on the official portal rather than assuming, but whether you scan a code or type the number, the destination should always be the registered project page.

What are the red flags and the checklist before paying?

Verification is quick, and a short discipline protects you from the most common traps. Work through the checklist below before any booking amount changes hands.

1. Ask the developer for the MahaRERA registration number before your first site visit or any payment.
2. Open the official MahaRERA portal and search that number under the registered projects section.
3. Confirm the promoter name on the portal matches the company or person collecting your payment.
4. Check that the registration is valid and note the declared project completion date on record.
5. Read the quarterly updates the promoter has filed to see real progress and any changes.
6. Look at the complaints and orders section for disputes against the project or the promoter.
7. Match the registration number on the brochure and the hoarding exactly against the portal record.

Red flags include a developer who is reluctant to share the number, a promoter name that does not match, a completion date that has quietly passed, or a brochure number that differs by even a digit from the portal.

Frequently asked questions

Is MahaRERA registration mandatory for every project?

Registration is mandatory for projects where the land exceeds 500 square metres or there are more than eight apartments across all phases. Below that threshold it is not compulsory, but most apartment projects in and around Mumbai are above it. A promoter cannot legally advertise or sell such a project without first registering it with MahaRERA.

How do I verify a MahaRERA registration number?

Go to the official MahaRERA portal, open the search for registered projects, and enter the registration number the developer provided. No login is needed. Read the project page that opens, and confirm the promoter name, the registration status and the completion date. The number on the brochure must match the portal record exactly.

What does a MahaRERA registration number look like?

In Maharashtra a project registration number usually begins with the letter P, or L for a layout, followed by a sequence of digits. The number is unique to the project. Your job as a buyer is to confirm that the same number appears identically on the brochure, the hoarding, the agreement and the official MahaRERA portal.

What should I do if the brochure number does not match the portal?

Stop and do not pay. A registration number that does not match the portal, a promoter name that differs, or an expired registration are all serious warnings. Ask the developer to explain in writing and verify any clarification against the portal. If the record cannot be reconciled, treat the project as unsafe and walk away.

The buyer in Thane did nothing clever. He simply checked the number before he trusted it, and the portal told him what the brochure could not. Verify the registration on the official MahaRERA portal before you pay, read the project page rather than the pamphlet, and let the regulator's record settle any claim a salesperson cannot.
