The data bazaar: how Indians' personal data gets sold, and what a list costs

TheRollNumber team · 11 November 2026 · 6 min read

The next part of our scams series. A stranger calls and knows your name, your bank or your child's exam rank. That is rarely luck. Personal data is bought and sold in India, sometimes for less than a rupee a person. Here is what a list costs, where it comes from, how it turns into a scam call, what the law does and doesn't do yet, and what you can do today.

  • 5 paisea mobile number's price in a 2026 police case, by our arithmetic
  • 412026 exam and institute databases on sale in July, MediaNama found
  • 31.09 lakhspam complaints filed in India in 2025
  • 771 crorecalls flagged as suspected spam in April 2026 alone

What a person costs

In Bilaspur in June 2026, the operator of a loan services office told police of having bought about one lakh mobile numbers for Rs 5,000. That is five paise each. Prices vary a lot by what's in the record, but they stay small.

What lists and lookups cost

Paid means police say that sum changed hands. Listed means a seller's asking price, with the seller's own record count. These are different kinds of data, so the list doesn't show a trend.

Where the data comes from

Hackers are only part of the story. Many lists start with someone who had ordinary access, or with nothing more than patience.

How one record becomes a call

A number alone is cheap. It becomes dangerous when it comes with a reason to call you. Tap a step to see how a caller's knowledge adds up.

What a caller knows, step by step
  1. An exam, a course enquiry or a shop asks for your name and number. Nothing feels unusual.

  2. In Lucknow, police say two men bought data of NEET-qualified students with low ranks online.

  3. A low rank means a family that is worried about a medical seat. The seller doesn't need to guess.

  4. Families were called about management-quota seats. Four complainants reported paying about Rs 45 lakh, Rs 20 lakh, Rs 38 lakh and Rs 23 lakh.

Why such a cheap list pays

A list only needs a few victims to pay for itself. Take the Hyderabad case reported in 2023.

One list, from purchase to payback
  1. Rs 30,000paid for 10,000 people's data
  2. Rs 1,000paid per SIM card
  3. Rs 26,000 a monththe home job offered
  4. Rs 2,600deposit asked of each victim
  5. About 12deposits pay back the list

Scale it up and the sums grow. In the Delhi telecom case, police said about 6,372 clients lost about Rs 1.94 crore to fake call centres using one company's customer data. In Noida in January 2026, police said a gang bought insurers' customer data "from the market". They seized 721 data sheets and arrested 13.

Students are a market too

Exam candidates are easy to target: a known age, a known goal, a deadline and a worried family. In July 2026, MediaNama found one database claiming over 15 lakh CUET UG 2026 records for Rs 6,999. It called people from a sample of over 500 students. Six answered, confirmed the details and hadn't known their data was on sale.

NEET PG aspirants reported calls from people who knew their ranks and scores, offering seats for Rs 25 lakh or more. No link between those calls and any listing has been proved. The exam board denied a breach at its level, and said the data moves across several bodies during counselling. A call like this can be the first step into a fake college or unapproved course.

What the law does, and doesn't do yet

India has a data protection law, but most of it hasn't started. This is the point people most often get wrong.

India's data protection law, in stages
  1. August 2023Parliament passes the Digital Personal Data Protection Act.
  2. November 2025Definitions and the Data Protection Board's legal basis start. The Rules are notified.
  3. August 2026The government tells the Lok Sabha the Board's members are still to be appointed.
  • Until then, you can't take a complaint to the Data Protection Board.
  • Penalties can reach Rs 250 crore, but they go to the government, not to the person harmed.
  • Your new rights will apply to companies you gave consent to. They won't reach a stranger who bought your number.

Other rules already apply. Companies must report cyber incidents to CERT-In within six hours, but that report doesn't go to you. If customer data leaks through a bank's outsourced vendor, RBI's rules say the bank "shall be liable to its customers for any damage". CERT-In tracked 29.44 lakh cyber security incidents in 2025, but that counts all incidents, not data breaches. We found no official yearly count of breaches.

Spam is the part you can see

Spam complaints reached 31.09 lakh in 2025, and more than 18 lakh in the first half of 2026. Still, in April 2026 telecom systems flagged about 771 crore calls as suspected spam, against fewer than 4 lakh complaints, TRAI's own memo shows. It also shows operators closed about 80% of complaints against registered telemarketers as invalid. TRAI says most spam comes from ordinary 10-digit numbers, which bypass your preferences. In a LocalCircles survey, 87% of respondents believed their data was already out there. That is a belief, not a measure, but it's a telling one.

What you can do today

There is no official service that shows which of your data is out. You can't take back a leak, so watch for its effects and make the data less useful.

  1. Don't trust a caller for knowing your details. Your rank, loan or policy number proves nothing. Those details are for sale. Hang up and call the official number yourself.
  2. Report spam within seven days. Use the TRAI DND app or 1909. Blocking only hides a number on your phone. Reporting helps trace it.
  3. Report fraud attempts. If no money was lost, use Chakshu. If money was lost, call 1930 at once.
  4. Check the SIMs in your name. Sanchar Saathi lists them, and you can report any you don't recognise.
  5. Pull your credit report. Every credit bureau must give you one free full report a year. Look for loans you didn't take.
  6. Give less. Ask why a form needs your number, your Aadhaar or your date of birth. Our post on Aadhaar and PAN photocopies explains what to do.
Call 1930If you've lost money to a caller, call the national cyber crime helpline straight away.

Where TheRollNumber fits

Apps are one more way data leaves your phone, and most people can't remember what they allowed. ADi Wallet's Device section shows which permissions each app on your phone holds, with family controls. It can't stop a leak, but it helps you see what you've given away. Businesses that collect documents to check people can use Checkkbox to work with a person's consent and fetch records from the source. Talk to us to see how.
