RERA number lookup — every state portal, direct links

RERA (Real Estate Regulatory Authority) is India's project-by-project registration mandate. Every residential project of 500+ sqm or 8+ units must register with its state RERA. Registration is your first check before any booking — unregistered projects cannot legally advertise, cannot take >10% advance, and have zero buyer-protection recourse.

How to verify a RERA number in 30 seconds

1. Go to the state RERA portal link above (match builder's claimed state)
2. Find "Registered Projects" search
3. Paste the exact RERA ID the builder shared (format varies by state)
4. Confirm: project name matches, builder name matches, status is "Registered" (not "Expired" or "Under Review")
5. Check the scheduled completion date and any extension filings
6. Cross-check the "Approved Layout" PDF — it must show the apartment, tower, and unit you're being sold

Red flags you'll spot

• RERA ID doesn't return a result: either fake, or for a different project phase
• Status "Expired": registration lapsed; legally cannot take new bookings
• Project claims RERA but shows "Under Review": application filed, not approved — still unregistered
• Completion date already passed: project is in delay; check extension filings and complaint volume
• Approved layout doesn't match brochure: classic switch-and-sell

See our full RERA verification guide for the legal detail, or RERA explained for the primer.

A dynamic lookup tool that queries all state portals via a unified search is on the roadmap. Until then, the direct portal links above are faster than any aggregator tool claiming to do it for you.
