Somewhere on a Mumbai flyover in 2026 hangs a glossy hoarding for a sea facing tower, all marble lobbies and infinity pools. In the top corner, smaller than the swimming pool but now legally required to be there, sits a small square QR code and a registration number. A commuter stuck in traffic scans it, and within seconds the official regulator page opens, showing whether the project is actually registered, what it has disclosed, and where it stands. That thirty second scan is the single easiest due diligence step a Maharashtra buyer has ever been handed.

The short answer. Since 2025, MahaRERA requires every project advertisement in Maharashtra, whether a hoarding, brochure, newspaper page, website or social media post, to display the project's MahaRERA registration number and a QR code that links to its official regulator page. For a buyer, this turns any advertisement into a verification tool: scan the code and read the source rather than the sales copy. The trade-off is none worth mentioning. The scan is free, takes seconds, and an advertisement that lacks the code is itself a warning sign.

What exactly did MahaRERA make mandatory?

MahaRERA now requires the registration number and a QR code to appear in every form of project advertisement. The rule, issued through a MahaRERA order in 2025, covers print, digital, hoardings, brochures and social media promotions alike, so a developer cannot advertise a registered project in Maharashtra without carrying these details. The QR code must link to the project's own page on the official MahaRERA portal, which is the authoritative source for that project's registration and disclosures. You can reach the same portal directly at maharera.maharashtra.gov.in if you prefer to search rather than scan.

The order also sets rules about how prominently these details must appear, so the registration number and code cannot be buried in tiny print in a corner where no one would look. The intent is plain: the regulator wants the verification route to be at least as visible as the phone number and the pretty pictures. For buyers, that visibility is the whole point, because a detail you cannot find is a detail you will not use.

What can you actually see when you scan the code?

Scanning takes you to the project's official regulator page, where the disclosures live. There you can confirm that the project is genuinely registered and read the registration number rather than take it on trust. You can typically see the promoter details, the registration validity, the declared completion timeline, and uploaded documents and quarterly updates that registered projects are expected to file. This is the same information the developer filed with the regulator, presented by the regulator, not by the marketing team. That distinction is the reason the scan matters.

Reading the source lets you catch the gaps between the advertisement and the filing. If a brochure promises possession next year but the registered completion date is later, you have found a question to ask before you pay. If the project name in the ad does not match the registered name, that too is worth resolving. The scan does not make decisions for you, but it hands you the facts you need to make them.

It also protects you from a common trap: the advertisement for one building that quietly borrows the credibility of a larger, better known project nearby. When you scan and land on the specific registered project, you are forced to confirm that the tower being sold to you is the tower on the record, with its own registration and its own timelines. A glossy campaign can blur those lines. The regulator page cannot, because it is tied to a single registration and shows only what belongs to it.

What does a missing QR code or registration number tell you?

A serious advertisement for a registered Maharashtra project should carry both, so their absence is a red flag you should not ignore. If a hoarding, brochure or social media post for a project promises apartments but shows no registration number and no QR code, treat it as a reason to slow down and ask direct questions. It may mean the project is not registered, that the advertiser is cutting corners, or that you are looking at something other than a compliant new project sale. None of those is a reason to hand over a booking amount.

This is also why the rule helps buyers even beyond the scan itself. It sets a simple, visible standard, so a buyer with no legal background can apply one quick test to any advertisement: are the registration number and code there, and do they lead to a real regulator page for the exact project being sold. If the answer is no on any count, you have learned something useful before spending a rupee.

How does this fit with checking MahaRERA yourself?

The QR code is a shortcut to verification, not a replacement for reading the regulator page carefully. Whether you scan a code or search the portal by hand, the real value comes from actually reading what the project has disclosed. Look at the registration status, the timelines, the financial and legal disclosures, and the quarterly progress updates. Our guide to the MahaRERA seventy percent escrow account rule explains one of the most important protections you should confirm a project follows. Together, the scan and a careful read give you a grounded picture of the project behind the glossy campaign.

Verification also pairs with understanding what you are being sold on paper. A registered project still uses area definitions that can confuse buyers, which is why our explainer on RERA carpet area and loading is worth reading alongside this. Scan to confirm the project is real and registered, then read closely to understand exactly what your money buys.

Does the rule apply to resale and agent advertisements too?

The registration discipline extends across the advertising chain, and registered agents are expected to follow the transparency rules as well. The clearest and most consistent application is to new project promotions by developers, where the registration number and QR code requirement is designed to bite. For resale flats in older buildings that predate registration, a project QR code may not apply in the same way, so your verification there leans more on society records, the share certificate and the title chain. The practical rule for a buyer is simple: for any new project being advertised, expect the code, and for a resale, fall back on the document checks that suit an existing building.

If you deal with an intermediary, confirm they are a registered agent and ask them to point you to the project's regulator page directly. A professional who works within the rules will do this without hesitation, because it costs them nothing and builds your trust. Reluctance to show you the official page is, again, information.

What are the seven steps to use the QR code well?

Turn the code into a habit with these steps.

1. On any project advertisement, look first for the registration number and QR code.
2. Scan the code and confirm it opens an official MahaRERA project page, not a developer microsite.
3. Check that the registered project name and promoter match the advertisement.
4. Read the registration status and validity to confirm the project is current.
5. Compare the declared completion timeline against any possession date the ad promises.
6. Open the uploaded documents and recent quarterly updates and read them.
7. If the code is missing, leads elsewhere, or shows mismatches, pause and ask written questions before paying.

Is a valid QR code a guarantee the project is a good buy?

No, a working QR code proves registration and disclosure, not quality or suitability. It confirms that the project exists on the official record and lets you read what the developer has filed, which is a strong foundation. But it does not judge construction quality, the fairness of the price, the strength of the title, or whether the home fits your budget and needs. Use the scan to establish that you are dealing with a real, registered project, then continue with the rest of your diligence, from the agreement terms to the loan and the legal review. Verification is the floor you build on, not the finished house.

Frequently asked questions

What does the MahaRERA QR code in an advertisement do? It links directly to the project's official page on the MahaRERA portal, where you can confirm the project is registered and read its disclosures. Since 2025, Maharashtra project advertisements must display this QR code and the registration number, giving buyers a fast way to check the source rather than relying on the marketing copy.

Is the QR code required on all project advertisements? MahaRERA requires the registration number and QR code across advertisement formats, including print, digital, hoardings, brochures and social media, for registered projects. The requirement was introduced through a MahaRERA order in 2025. A new project advertisement that carries neither the registration number nor a working QR code should be treated as a warning sign.

Where does the QR code take me? It opens the project's page on the official MahaRERA portal at maharera.maharashtra.gov.in. That page shows the regulator's record of the project, including registration status and validity, promoter details, declared timelines and uploaded documents. Because the regulator presents this information, not the developer's marketing team, it is the authoritative source to rely on.

Does a valid QR code mean the project is safe to buy? No. A valid code confirms registration and lets you read official disclosures, but it does not judge construction quality, price fairness or title strength. Treat the scan as the first verification step, then complete your title check, agreement review, loan due diligence and a lawyer's review before committing money to any registered project.
