Is a RERA number legally required on a real estate website?
Yes, for any project that falls under the Real Estate (Regulation and Development) Act. If a project is registered with RERA, which covers most residential and commercial developments above the size threshold set by the state authority, the registration number must be displayed on all advertisements, marketing materials, brochures and, in practice, the website pages promoting that project. Uttar Pradesh RERA maintains its own registry, and a serious buyer will often check a project's registration number against it before proceeding, so displaying the number correctly is not just a legal box to tick, it is a genuine trust signal. Some smaller or ongoing resale transactions may not require a fresh registration, and the exact rule depends on the transaction type, so we ask for your registration details or your RERA consultant's confirmation before publishing a project page, rather than guessing at whether it applies.
