Your data passed through the dealer, the manufacturer, the insurer and the registration process. Block automobile marketing on DND, complain about each call, and ask the dealer in writing which partners received your data.
Safety first. Threatened or in danger: call 181 (women) or go to the nearest police station. Lost money: call 1930 at once.
Your rights
- Right to have your vehicle owner data protected. MoRTH's policy says citizen searches show only non-personal details with the owner masked, and private companies need your consent through an Aadhaar based OTP for personal data.
- Right to stop marketing calls and SMS. Register DND by sending FULLY BLOCK to 1909. A spam complaint made within 7 days is valid and your telecom company must act on it (TRAI TCCCPR, 2018, as amended in 2025).
- Right to withdraw consent (from 13 May 2027). Withdrawing must be as easy as giving consent, and the company must then stop processing (DPDP section 6(4) and 6(6)).
- Right to compensation for deficiency in service. Under the Consumer Protection Act, 2019 you can claim compensation before a Consumer Commission. File within 2 years.
- DPDP rights from 13 May 2027. You can ask what data the company holds and who it shared it with (section 11), ask for correction or erasure (section 12), and complain to the company, then to the Data Protection Board (sections 13 and 27). The company answers for its processors (section 8(1)).
How to fight it, step by step

What people tried and what worked
- People asked the dealer, ignored or blocked callers.
- Dealers usually denied sharing. A written Letter 2 makes the denial a record.
Based on reports on public forums. Paraphrased, with no usernames or personal details. What worked for one person may not work for you; the numbered steps above are the official route.
Not legal advice. This page explains the rules in plain words so you can act. Consult a lawyer before you sue anyone or send a legal notice. Laws and portals change; check the linked official source.
Step 1: stay safe and find out who it is
- Do not share an OTP, PIN, password or card number.
- Ask for their name, company, role and ID. Write it down.
- Hang up and call the company on a number you find yourself, on its official website or app.
- Ask whether this person works for the company or a partner. Ask for a written answer (Letter 1 below).
If it is genuine: hold the company accountable
Which rules this may break
- MoRTH Policy for Data Sharing from the National Transport Repository: masking for citizen search; consent through Aadhaar OTP for private sector access to personal data.
- TRAI TCCCPR, 2018 (amended 2025): BLOCK 5 covers consumer goods and automobiles.
- IRDAI 2024 regulations if the calls are from insurers or brokers.
What the company must do, and by when
- Stop calling once you have registered DND or withdrawn consent.
- Tell you, if you ask, where it got your number.
- From 13 May 2027: erase your data once the purpose is over or you withdraw consent (section 8(7)), and answer for its lead vendors (section 8(1)).
Letter 1: ask them to confirm who the caller is
Send it through the official channel. Keep a copy and the acknowledgement.
To: The Grievance Officer, [Dealer, manufacturer or service centre name] Subject: Please confirm whether this person works for you Dear Sir or Madam, I am your customer. My vehicle registration number: [number]. On [date] at [time] I received a call or message from [phone number]. This is not an official number. The person said they were [name], [role or employee ID], from the dealer. They knew my [list the details they knew]. Please confirm in writing within 7 days: 1. Whether this person is your employee, agent, insurer, finance partner, lead vendor or partner. 2. If yes, their name, role and the agency they work for. 3. Whether you allow staff or agents to contact customers from personal numbers. 4. If they are not connected with you, please say so, so I can report the number. Name: Registered mobile number: Date:
Letter 2: ask how your data got there
To: The Grievance Officer, [Dealer, manufacturer or service centre name] Subject: How did my personal data reach a personal phone? Complaint number [if any] Dear Sir or Madam, On [date] a person connected with you, [name if known], contacted me from a personal number [number] and knew my [details]. [Describe what they did.] Please tell me in writing: 1. What personal data about me this person could see, and through which system or app. 2. Whether you shared my data with any agency, insurer, finance partner, lead vendor, partner or processor, and their names. 3. How my data reached a personal phone or account outside your official systems. 4. What action you have taken against the person or agency, including suspension while you investigate. 5. What you have done to stop this happening again. 6. The name of every company you bought my number from or sold it to. MoRTH's data sharing policy says private companies may get personal vehicle owner data from the national transport database only after the owner's consent through an Aadhaar OTP, and that citizens searching any vehicle see only non-personal details with the owner masked. Marketing calls are covered by TRAI's TCCCPR, 2018. From 13 May 2027, sections 8 and 11 of the Digital Personal Data Protection Act, 2023 also apply. Please reply within 30 days. If I do not hear from you, I will escalate to TRAI's complaint route through my telecom company, the National Consumer Helpline and, from 13 May 2027, the Data Protection Board. Name: Registered mobile number: Date:
Evidence to keep
- Screenshots of calls and messages with numbers, dates and times.
- Order, booking, policy or account numbers.
- Your complaint numbers and the company's replies.
- A note of what the caller knew or did.
More in the evidence checklist.
Can you sue? What realistically happens
- Consumer Commission: the most practical route for compensation. Cheap, no lawyer needed, file within 2 years.
- IT Act section 43A (until 13 May 2027): if the company was negligent with sensitive personal data (passwords, bank or card details, health records, biometrics) and that caused wrongful loss or gain, it must pay compensation. Claims up to Rs 5 crore go to your State's IT Secretary acting as Adjudicating Officer (section 46); larger claims go to a court. Appeal within 45 days (section 57). Your phone number and address alone are not sensitive data under the 2011 Rules.
- Civil suit for damages: possible, but slow and costly. Section 61 of the IT Act bars civil courts from matters the Adjudicating Officer can decide.
- Police: only where there is a crime, for example a person who disclosed your information in breach of a contract to cause wrongful loss or gain (IT Act section 72A, up to 3 years), identity theft (66C), cheating by impersonation (66D), stalking or threats.
- Realistic outcome: most people get results from a firm written complaint and the regulator or ombudsman. Courts take years. Consult a lawyer before suing.
From 13 May 2027: the Data Protection Board
From 13 May 2027 the DPDP Act's duties apply. The company is responsible for processing done by it or by anyone processing on its behalf (section 8(1)), may use a processor only under a valid contract (section 8(2)), must protect your data with reasonable security safeguards (section 8(5)), and must tell you and the Board about a breach (section 8(6)). It may use your data only for the lawful purpose you agreed to (sections 4 to 6). Section 44(2) removes IT Act section 43A from that date. Complain to the company first; if it does not resolve it, complain to the Data Protection Board. The Board can impose penalties up to Rs 250 crore, but penalties go to the Government (the Consolidated Fund of India, section 34), not to you. For money, use the ombudsman or the Consumer Commission. Appeals from the Board go to TDSAT within 60 days (section 29).
If it is fake: urgent steps
- If anyone asks for an OTP, PIN or payment, stop. It may be fraud.
- Call 1930 if money was lost, then file on cybercrime.gov.in.
- Report the number on Chakshu (Sanchar Saathi).

Keep this ready before you start:
- The phone with the SIM you want to protect.
- To block all commercial calls and SMS except transactional ones, send an SMS with the text FULLY BLOCK (or BLOCK 0) to 1909.
- To block all except transactional and service messages, send BLOCK PROMO (or BLOCK 50) to 1909.
- To block only one category, send BLOCK 1 (banking, insurance, financial products, credit cards), BLOCK 2 (real estate), BLOCK 3 (education), BLOCK 4 (health), BLOCK 5 (consumer goods and automobiles), BLOCK 6 (communication, broadcasting, IT), BLOCK 7 (tourism and leisure) or BLOCK 8 (food and beverages).
- You can also dial *1909*0# (USSD), or call 1909 and follow the voice menu, or use the TRAI DND app.
- Keep any reply SMS you get from your operator.
- To complain about a spam SMS or call, send an SMS to 1909 in this format: The UCC, XXXXXXXXXX, dd/mm/yy. Put the spam text or a short description first, then the sender's number or header, then the date.
- Do it within 7 days of the spam. Under TRAI's 2025 amendment a complaint is valid if it has the sender's number, your number, the date and a short description.
- Save the complaint ID your operator sends.
