Indians lose money every day to phone calls from people pretending to be a bank officer, TRAI agent, FedEx executive, customs officer, or Aadhaar centre. The script changes. The pressure tactics are identical. If a caller threatens you, demands your OTP, asks you to install an app, or insists on immediate payment to clear your name, hang up. This guide covers every common version and how to spot it in the first 30 seconds.
Who this is for
Anyone in India who answers a phone call from an unknown number. The script works on lawyers, doctors, working professionals, students, and senior citizens. Education is not a defence. Recognising the pattern is.
The bigger picture
The umbrella term for this fraud is vishing, short for voice phishing. The Indian Cyber Crime Coordination Centre (I4C) under the Ministry of Home Affairs reports vishing as one of the fastest-growing complaint categories on cybercrime.gov.in. The 1930 helpline gives citizens a fast route to report financial fraud calls and trigger bank-side account holds.
Per government data reported by Business Today and The Hindu through 2024 and 2025, cumulative cybercrime losses crossed multiple thousand crores annually, with phone-based fraud forming a significant share. The RBI, TRAI, and Department of Posts have issued repeated advisories. The infrastructure exists. The scams continue because most victims have heard of them in general terms but do not have a 30-second checklist for the specific call in front of them. This article fixes that.
5 common impersonation calls
1. Fake bank or credit card calls
The script. A caller claims to be from your bank’s fraud team, credit card division, or customer support. They mention a suspicious transaction, a card expiry, a KYC update, or a reward redemption. They sound calm and professional, and ask you to confirm your card number, CVV, OTP, or UPI PIN to verify your identity.
The real version. Indian banks do not ask for OTP, CVV, UPI PIN, net banking password, or full card number on any phone call. They also do not ask you to install screen sharing apps like AnyDesk or TeamViewer, or click links from SMS to verify yourself.
The defence. Hang up. Call back the number printed on the back of your debit or credit card, or the toll-free number on your bank’s official website. Never trust a number provided by the caller.
2. Fake TRAI calls
The script. A recorded voice or live caller claims to be from TRAI. They say your mobile number will be disconnected in 2 hours due to complaints, illegal activities, or KYC non-compliance. They tell you to press 9 to speak with a TRAI officer, who then transfers you to a fake police officer claiming your number was used in a money laundering case. This is often the entry point to the digital arrest pattern.
The real version. TRAI is a regulator. It works with telecom operators (Jio, Airtel, Vi, BSNL), not directly with subscribers. TRAI does not call individuals about number disconnection or coordinate with police investigations. The TRAI itself has issued public statements clarifying this. Disconnection notices come through SMS from official sender IDs, not robocalls.
The defence. Disconnect immediately. Do not press any number. Do not engage. If you have a real concern about your number, contact your telecom operator directly.
3. Fake courier and parcel calls (FedEx, DHL, Blue Dart, India Post)
The script. A caller says a parcel sent in your name from Mumbai or Delhi to a foreign country has been intercepted by customs. The parcel contains drugs, fake passports, or contraband. They ask if you sent it. When you deny, they say your Aadhaar has been misused, and transfer you to a fake customs or police officer who escalates the threat. This is often the entry point to a full digital arrest scam.
The real version. FedEx, DHL, Blue Dart, India Post, and other courier companies do not call individuals about intercepted parcels with criminal contents. Customs investigations do not happen over the phone. If a parcel is genuinely intercepted, formal notices arrive in writing. The FedEx India, DHL India, and Blue Dart official websites have published warnings about exactly this scam.
The defence. Hang up. Do not let yourself be transferred to any officer. If you are expecting a parcel, contact the courier through their official app or website, not the number that called you.
4. Fake customs and import duty calls
The script. A caller claims a parcel from abroad (often a gift, iPhone, or merchandise from a foreign friend) is held at customs in Delhi or Mumbai. To release it, you need to pay customs duty, a processing fee, or an anti-money-laundering deposit immediately via UPI or to a personal bank account. Sometimes the parcel is fictional. Sometimes it is connected to romance scams where rapport was built over weeks.
The real version. Indian Customs does not call individuals to demand duty payment to a personal bank account or via UPI. Real customs duty is paid through formal channels: the customs office, the courier company’s official channel, or the Indian Customs Electronic Gateway (ICEGATE). Customs officers do not threaten arrest over the phone.
The defence. Hang up. If you have no parcel pending, the call is fake. If you are expecting something, contact the courier through their official website. Never transfer money to a personal account based on a phone instruction.
5. Fake Aadhaar centre or UIDAI calls
The script. A caller claims to be from UIDAI, an Aadhaar centre, or the Aadhaar helpdesk. They say your Aadhaar is about to be deactivated, has been linked to a fraudulent SIM card, requires biometric reverification, or needs PAN linking by tonight. They ask you to share your Aadhaar number, the OTP sent to your registered mobile, or to install an app.
The real version. UIDAI does not call individuals to demand Aadhaar updates, OTPs, or biometric reverification. Communications go through formal channels at uidai.gov.in and via SMS from official sender IDs. UIDAI has issued repeated advisories clarifying it does not make such calls.
The defence. Hang up. Never share your Aadhaar OTP. Never install an app based on a phone call. If you have a real Aadhaar concern, visit your nearest Aadhaar Seva Kendra or use the official UIDAI website.
6 red flags that apply to every impersonation call
These red flags are universal. If any one of them appears, hang up. Do not wait for confirmation from a second.
1. Urgency framed as a deadline
Your number will be disconnected in 2 hours. Your card will be blocked tonight. Customs will destroy your parcel tomorrow. Real banks, regulators, and government agencies do not impose phone-based 2-hour deadlines on individual citizens.
2. Demand for OTP, PIN, CVV, password, or biometric
No legitimate organisation asks for these over a phone call. None. This single rule covers most variations of the scam.
3. Demand to install an app or share your screen
AnyDesk, TeamViewer, QuickSupport, and similar screen sharing apps are weaponised in scam calls. Real customer support of any Indian bank or government agency never asks you to install these.
4. Threat of arrest, deactivation, or legal action
The threat is the manipulation. Real legal processes do not arrive as cold calls with arrest threats. Banks do not block accounts via phone threats. Regulators do not deactivate services through phone calls.
5. Demand for payment to a personal bank account or UPI ID
Customs duty does not go to a personal account. Bank fines do not go via UPI to an individual. Government dues do not get collected by phone instruction. Any payment demand to a personal account based on a phone call is the scam.
6. The caller stops you from disconnecting or contacting anyone
Do not hang up. Do not tell anyone. Do not check with your bank. Isolation is the core mechanism. Any caller who tries to prevent you from disconnecting or verifying is exactly the caller you must disconnect from.
What to do if you got a call
- Disconnect. The longer the call lasts, the more control they have.
- Verify through the official channel. Bank concern? Call the number on the back of your card. TRAI claim? Contact your telecom operator. Courier claim? Use the official app or website of FedEx, DHL, Blue Dart, or India Post. Aadhaar concern? Visit uidai.gov.in or the nearest Aadhaar Seva Kendra.
- Save evidence. Caller number, time of call, screenshots of any messages, recordings if your phone captured the call.
- Report to 1930. Even if you did not lose money, reporting helps I4C track and block the calling numbers. (I4C FAQ)
- Warn your family. Share this article with parents, grandparents, and anyone else in your household. The fewer people who fall for the first message, the smaller the scam.
What to do if you already shared info or paid money
Speed is the single biggest factor in recovery. Move fast.
- Call 1930 immediately. The national cybercrime helpline operates 24/7. They will guide you on bank holds and next steps.
- File a formal complaint at cybercrime.gov.in within 24 hours. Required for any recovery action and creates the formal record.
- Notify your bank’s fraud team in parallel. Banks can sometimes freeze recipient mule accounts within hours of a complaint. The earlier they know, the better the recovery odds.
- If you shared OTP or PIN, change your passwords and PINs immediately. Internet banking, UPI apps, bank app. Block your card if you shared card details.
- File an FIR with your local police cyber cell. Required for insurance claims and any subsequent legal action.
- Preserve all evidence. Call logs, screenshots, transaction details, any audio. Do not delete anything.
How real authorities actually work
Banks communicate through SMS from registered sender IDs, app notifications, and in-branch interactions. They never ask for OTP, PIN, CVV, or net banking password on phone calls. TRAI does not contact individual subscribers at all. Courier companies use their app, SMS, or email and do not call about intercepted parcels with criminal contents. Indian Customs uses written notices and official payment gateways, never personal UPI IDs. UIDAI communicates through SMS from official sender IDs and through uidai.gov.in, never demands Aadhaar OTPs over phone. Police and CBI conduct investigations in person, with documentation. For the specific subtype where scammers pose as police on continuous video, see our digital arrest scam guide and generic police impersonation guide.

How this differs from the digital arrest scam
We get this question often. The digital arrest scam is a specific subtype where scammers pose as CBI, ED, NCB, or police officers and keep you on continuous video custody for hours or days, often pressuring multi-lakh or multi-crore transfers under fake legal threats.
The broader phone impersonation category covered in this article is wider. Bank fraud calls, TRAI scams, courier impersonation, customs demands, and Aadhaar calls often do not involve video at all. Many of these are simpler vishing calls aimed at extracting an OTP, harvesting KYC data, or pressuring a single transfer. They are common entry points to the digital arrest pattern but are also scams in their own right.
Understanding both helps. The broader pattern of unknown caller plus urgency plus authority claim plus demand for OTP, app install, or payment is the underlying shape. Recognise that shape and most variations stop working.

Frequently asked questions
How can I tell if a call from my bank is real?
Real banks never ask for your OTP, UPI PIN, full debit or credit card number, CVV, or net banking password over a phone call. They also never ask you to install an app or share your screen. If a caller asks for any of these, hang up and call the official bank number printed on the back of your card or on the bank website.
Does TRAI call people to disconnect their numbers?
No. TRAI is a regulator. It does not contact individual subscribers about number disconnection, KYC, or police cases. All TRAI communications are with telecom operators, not customers. Any call claiming to be from TRAI threatening to deactivate your number is a scam, no exceptions.
How does the fake courier scam work?
A caller claims to be from FedEx, DHL, Blue Dart, or India Post, says a parcel in your name contains drugs, fake passports, or contraband, and threatens arrest unless you cooperate with a fake police officer they transfer you to. This is a script. No real courier company makes calls like this. Hang up.
What should I do if I already shared OTP or paid money?
Call 1930 immediately. File a formal complaint at cybercrime.gov.in within 24 hours. Notify your bank’s fraud team in parallel. Banks can sometimes freeze the recipient account within hours if you report fast. Save all evidence including call logs, screenshots, and transaction details. Do not delete anything.
How is this different from the digital arrest scam?
Digital arrest is a specific subtype where scammers pose as CBI, ED, NCB, or police officers and keep you on continuous video custody for hours or days. The broader phone impersonation category covers banks, TRAI, couriers, customs, and Aadhaar centres, which often do not use video at all. Many of these are simpler vishing calls aimed at OTP, KYC data, or single-transaction theft.
