How your number reaches fifty brokers after one enquiry, and how to stop it

Enter your phone number once on a listing portal, a project microsite or an exhibition kiosk, and it stops being your contact detail and becomes a "lead" — a commodity packaged and sold, often repeatedly, to brokers and telecallers chasing the same inventory. That is why the calls keep coming months after you stopped searching. It is a business model, not a leak.

The regulator's tools help more than most people assume. Registering on TRAI's DND (NCPR) registry — by SMS or call to 1909, or through the TRAI DND app — lets you block all commercial communication or specific categories, real estate included. Violations can be reported to 1909 within three days of the call; registered telemarketers face escalating penalties, and unregistered numbers that keep dialling risk disconnection. It will not stop every caller, but it thins the herd and creates a paper trail.

The rest is consent hygiene. Use a secondary SIM for property hunting and keep your primary number out of forms. Untick pre-checked marketing-consent boxes, and when a cold caller reaches you, ask where they got the number and demand removal. India's Digital Personal Data Protection Act, now being phased in, gives you the right to withdraw consent and seek deletion of your data from platforms that hold it.

The durable fix, though, is architectural: platforms designed so your number is never exposed in the first place. Finclara's listings work on a masked-identity model — browsing is free and anonymous, communication stays inside the platform, and your contact details are revealed only at the point you choose to connect. No lead files, nothing to resell.
