What this category covers
Telemarketing in India is a ₹32,000-crore industry. Most calls are technically legal under TRAI’s Telecom Commercial Communications Customer Preference Regulations, but the line between a legitimate registered telemarketer (140-series) and an unregistered bulk dialer using cheap virtual SIMs is razor thin. Real-estate touts in Gurugram, Noida and Pune call from the +91 70 / +91 80 / +91 90 series, run through the same call centres for the same builders, and rotate numbers every few days to evade your block list.
Even when a telemarketer is genuine, sales-pressure techniques can border on harassment — 16+ daily callbacks for a property visit, 03:00 AM SMS broadcasts, and ‘your loan is pre-approved’ pitches that gradually fish for sensitive data. The community reports on PhoneLookup help separate aggressive but legitimate telemarketers from outright bait-and-switch operators.
Red flags
- Multiple daily callbacks from rotating numbers in the same circle.
- Refusal to disclose the parent company’s name and physical office address.
- An offer that requires you to share Aadhaar or PAN before any product is delivered.
- Pressure to attend a ‘free’ property site visit with a cab pickup — once on site, refusal to leave without a token amount.
- Edtech demos that quickly pivot into pressure for a ₹45,000 — ₹1.5 lakh course loan.
What to do
- Register for DND on the Sanchar Saathi portal or by dialling 1909.
- Block aggressive numbers and report them on PhoneLookup. Repeat offenders surface to the top of the trending pages.
- For repeated breach of DND, file a complaint with TRAI via the Sanchar Saathi UCC-DND chatbot within seven days of the offending call.
- Never share Aadhaar, PAN, OTP or bank details with any inbound telemarketer — even legitimate ones do not need them at the pitch stage.
Real-world examples
‘Free site visit’ to a Greater Noida flat
A polite caller offers a free cab pickup to view a 2BHK flat at ₹39 lakh. On arrival, sales pressure to book with a ₹1 lakh token escalates into refusing to leave the marketing office until partial payment is made.
Edtech course loan
A free 1-hour career counselling demo with a “mentor” ends with a ₹1.2 lakh course offer financed through an instant loan signed on a tablet during the call. The course delivery often fails to match the demo, while the loan keeps deducting.

Frequently asked questions
Can a telemarketer legally call after I register for DND?
Only entities you have explicitly opted in to (e.g. your bank, your insurer) can call you after DND registration. Calls from other registered telemarketers are a breach — 1909 / Sanchar Saathi exists to fine them.
Why does the same builder call me from 12 different numbers?
Builders outsource lead generation to multiple call centres, and each centre uses rotating SIMs to bypass blocks. Reporting the numbers on PhoneLookup links them to the same campaign so others recognise the pattern.
