AU Cosmos Corner Siddharth Vihar — RERA & Developer Details
The legal name, promoter and RERA status behind AU Siddharth Vihar
Everything you need to independently verify AU Siddharth Vihar before booking — its registered name, promoter, UP RERA number and how to check it yourself.
Project Identity: AU Siddharth Vihar = AU Cosmos Corner
Many buyers searching for "AU Cosmos Corner Siddharth Vihar" or "Cosmos Corner Siddharth Vihar" are looking for the same project marketed as AU Siddharth Vihar. AU Cosmos Corner is the legal, RERA-registered name filed by the promoter — Cosmos REIT Private Limited, part of the AU Real Estate group. The two names refer to the identical residential high-rise development in Siddharth Vihar, Ghaziabad.
This is a common and legitimate practice in Indian real estate: a project's public-facing marketing name can differ from the name filed with the state RERA authority. What matters for a buyer is confirming that the marketing name and the RERA-registered name genuinely correspond to the same land parcel, promoter and layout — which you can do directly on the UP RERA portal.
