Here are the best websites to find RERA-registered / RERA-approved apartments in Delhi, and how to use them:

1. Delhi RERA — official regulator site (authoritative source)

   • Use the official Delhi RERA portal to search registered promoters/projects and to verify a project’s RERA number before you buy. (Delhi RERA’s project/promoter lists and contact details are published there). (paisabazaar.com)

2. Major property portals that show RERA registration on listings

   • 99acres — lists projects and typically shows the RERA registration number on the project page.
   • MagicBricks — filters/search pages often include RERA-registered projects and display the RERA ID.
   • NoBroker — includes a RERA status/RERA number on many Delhi listings.
   • Housing.com — shows RERA details on new‑project pages and filters.
   • Squareyards, RealEstateIndia, and similar real‑estate marketplaces — have dedicated “RERA registered” project sections. (Squareyards.com)

3. Aggregator / RERA-listing directories

   • Some aggregator sites (e.g., indianrera.org listings and private RERA‑directory pages) collect state RERA portal links and let you jump to Delhi RERA search pages. Use these only as a convenience — always verify on the Delhi RERA portal itself. (indianrera.org)

Quick checklist for using these sites safely

• Always note the project’s RERA registration number shown on the portal/listing.
• Verify that RERA number directly on the Delhi RERA portal (official) before signing any agreement. The regulator’s site is the authoritative record. (paisabazaar.com)

If you’d like, I can:

• Look up a specific apartment/project name and confirm its Delhi RERA registration number for you, or
• Give direct instructions (step‑by‑step) for verifying a RERA number on the Delhi RERA website. Which would you prefer?
