Phone scams: a plain-English guide

Why these calls work on sensible people

Phone scams do not succeed because people are gullible. They succeed because they are built by professionals to bypass careful thinking, and because they arrive without warning at an ordinary moment.

Three ingredients do the work. Authority — they claim to be your bank, the police, the tax office, or a well-known company. Urgency — something bad will happen in minutes or hours unless you act. Isolation — you are told not to hang up, not to tell anyone, not to discuss it at the counter. Each one is there to stop you doing the one thing that would end the call: checking.

If you notice all three in a single phone call, you can stop analysing. That combination does not occur in legitimate business.

Caller ID proves nothing at all

This is the single most important thing to know, and most people do not. The number shown on your phone is supplied by the caller's system, and it can be set to anything. Fraudsters routinely display the genuine number of the bank, the police station or the government department they are pretending to be.

So "it came up as my bank's real number" is not evidence. Neither is the caller knowing your name, your address, your bank, or a recent transaction — personal details leak in data breaches constantly and are bought and sold. A caller who knows things about you is not thereby legitimate; they have simply done the preparation.

The main scripts

The bank security call

They say there is fraud on your account. They may ask you to move money to a "safe account", to read out a code they are sending you, or to install software so they can help. All three are the fraud itself.

Remember three absolutes. There is no such thing as a safe account. No bank will ever ask you for a code. No bank needs to connect to your computer. Any of these means the call is fraudulent, whoever it appears to be from.

The police or tax office call

You are told you owe money, that a warrant exists, or that your identity has been used in a crime. There may be threats of arrest. Sometimes you are asked to help with an investigation and to keep it confidential.

Police and tax authorities do not demand immediate payment by phone, do not accept gift cards or cryptocurrency, and do not ask members of the public to assist with secret operations. Real matters arrive in writing and allow you time.

The computer support call

Someone says your computer is infected or your internet connection has a problem. They want remote access. Once they have it they can see everything, take passwords, and empty accounts — and some stage a fake refund that appears to overpay you, then ask you to send the difference back.

No legitimate company monitors your computer and telephones you about it. Ever.

The family emergency call

A distressed voice that sounds like your child or grandchild. An accident, an arrest, a lost phone, an urgent need for money, and instructions not to tell anyone else yet.

Voices can now be copied from a few seconds of video posted online, so sounding right proves nothing. Hang up and ring them on the number already in your phone. Agree a family check word in advance, and ask for it.

The refund or overpayment call

You are owed money — from a company that has gone under, an overcharge, a cancelled subscription. To process it they need your bank details, or they need access to your computer to "complete the transfer". Then something goes wrong and you have apparently been paid too much.

Nobody needs remote access to your computer in order to refund you.

The one habit that defeats all of them

Hang up and check for yourself, using a number you already have.

Not a number they gave you. Not a number from a text or email. The number on the back of your bank card, in your phone's contacts, or on a statement you already had.

This works because you do not have to spot anything. It does not matter how professional they sound, how much they know, or what appears on your screen. If you verify through a channel they do not control, the scam fails.

One practical detail: if you can, use a different phone to call back, or wait a couple of minutes first. On some older landlines a caller can hold the line open so that redialling reaches them again. A mobile phone avoids this entirely.

Expect them to argue. You will be told there is no time, that hanging up will make things worse, that you must not tell anyone. That pressure is not a reason to stay on the line. It is the clearest confirmation you will get.

Things that are always a scam

• Any request to move money to a different account for safekeeping.
• Any request for a one-time code, PIN, password, or full card number.
• Any request to pay by gift card, voucher or cryptocurrency.
• Any request to install software or allow remote access to your computer.
• Any instruction to keep the call secret from your family or your bank.
• Any courier being sent to collect your card, cash, or documents.
• Any demand for immediate payment to avoid arrest.

There are no exceptions to this list. You do not need to weigh up the circumstances.

Practical steps for a family

1. Agree a check word everybody knows, and practise using it once so it feels normal.
2. Agree that hanging up is always fine. Nobody legitimate will be offended, and rudeness is not a risk worth managing.
3. Agree that calling to check is never a nuisance. Then answer when they call. People lose money mainly when they feel they have nobody to ask.
4. Set up transaction alerts with the bank, so unexpected payments are visible immediately.
5. Write the bank's real number on a card kept by the phone, so it is there in the moment.
6. Talk about the scams you hear about, casually and regularly. Someone who has heard a scam described recognises it much faster.

If money has already gone

Call the bank immediately — the first hours matter more than anything else. Then report it through our reporting page, which lists the right agency for your country. Keep everything: numbers, times, names, and what was said.

And be prepared for a second approach. Anyone who contacts you afterwards offering to recover the money for a fee is part of the same operation. No legitimate service asks for payment in advance to get scammed money back.

One last thing, aimed at families. The person this happened to will often be more distressed about having been deceived than about the money. Treat it as something that was done to them, because it was. People who are met with blame stop reporting, and stopping reporting is what allows it to happen a second time.
