I’m not finding a reliable public listing specifically for “Jain Bhuvan” in Ghatkopar, Mumbai with a confirmed phone number. The results I see are for:

• Jain Bhuvan, Bhandup (West), Mumbai – Phone: 022‑25941713 (this is Bhandup, not Ghatkopar).

Because phone numbers and halls/derasars can change, it’s better to:

1. Ask any local Ghatkopar Jain Sangh / Derasar Pedhi office; they usually keep updated contact details for nearby bhavans and upashrays.
2. Check with Shree Ghatkopar Jain Sangh / nearby derasars in Pant Nagar, Navroji Lane, Shanti Nagar etc.; they should know the current number for Jain Bhuvan if it is active in Ghatkopar.
3. If you have the exact address landmark (road name or nearby derasar), share it with me and I can try again more precisely.
