Your phone rings once or twice and stops.
You don’t recognise the number, but curiosity kicks in. Was it a delivery driver? A doctor’s surgery? Someone from work? Perhaps it was important.
Calling back feels harmless.
Another increasingly common version starts differently. You answer and hear an automated voice telling you there is a job opportunity waiting for you. The message may sound professional and may encourage you to continue the conversation or make contact through another service.
Ofcom, the UK’s communications regulator, issued fresh consumer advice on 2 October 2026 warning about both fake job-offer calls and suspicious missed calls. The regulator says these calls can be designed to persuade people to call back, after which criminals may attempt to obtain personal information, pressure them into making payments or direct them towards expensive premium-rate numbers. www.ofcom.org.uk
That doesn’t mean every unfamiliar call is fraudulent. Genuine businesses, delivery companies and organisations sometimes call from numbers you haven’t saved.
The important thing is knowing how to respond without turning an unexplained call into an unnecessary risk.
Why a Scam Call May Last Only a Few Seconds
A scammer doesn’t always need to speak to you during the first call.
Sometimes the objective is simply to make you call them.
Imagine you’re working and your phone rings briefly from an unfamiliar number. By the time you pick it up, the call has ended.
There is no voicemail and no text explaining who called.
Calling straight back may feel like the obvious thing to do, particularly if you’re expecting a delivery, waiting for an appointment or applying for jobs.
But an unexplained missed call doesn’t create an obligation to respond.
Ofcom advises people not to call back an unfamiliar number simply because it appeared as a missed call, particularly when the number uses certain ranges that can involve higher charges. www.ofcom.org.uk
A legitimate caller with something important to discuss often has other ways to identify themselves. They may leave a voicemail, call again, send an expected message or provide contact information through an organisation’s official website.
Waiting for that additional context is safer than treating every missed call as urgent.
The Fake Job Offer Version Can Sound Surprisingly Convincing
The second pattern highlighted by Ofcom uses supposed employment opportunities.
You may answer the phone and hear a recorded message claiming that your CV has been selected, that recruiters are looking for workers or that an attractive job is available.
For someone actively looking for work, the timing can make the message particularly convincing.
Suppose you’ve applied to six employers during the previous week.
An automated call arrives saying:
“We have a job opportunity for you. Please contact our recruitment manager to discuss the position.”
Your first thought may be that one of those applications has progressed.
That’s exactly why context matters.
Instead of following instructions in the unexpected call, stop and ask whether the contact matches anything you actually applied for.
A genuine recruiter should be able to identify the company, role and reason for contacting you. You should also be able to verify the organisation independently.
Be especially cautious if the supposed job quickly turns into requests for money, bank information, identity documents or unusual financial transactions.
A legitimate recruitment process should make sense as a recruitment process.
If the conversation starts as “we have a job for you” and rapidly becomes “send us money”, something is seriously wrong.
Never Let the Caller Create the Urgency for You
Pressure is useful to scammers because careful thinking takes time.
A caller may say an opportunity will disappear unless you act immediately. Someone pretending to represent a bank may claim your account is under attack. A supposed delivery company may insist a payment is required now.
Different stories can use the same psychological trick:
Act before you verify.
The safest response is to reverse that order.
Verify first. Act afterwards.
If somebody says they’re calling from your bank, end the call and contact your bank yourself using a trusted number, such as the one printed on your card or shown in its official app.
If somebody claims to represent an employer, search for the organisation independently and use contact information from its official website.
Don’t rely on a telephone number, website address or contact details supplied by the unexpected caller as your only method of verification.
A scammer who controls the original conversation can also provide a fake route for supposedly “checking” that conversation.
Taking control of the contact breaks that chain.
Be Careful About What You Reveal During the Call
People sometimes think a scam becomes dangerous only when they give away a password or transfer money.
Those are certainly serious outcomes, but smaller pieces of information can also be valuable.
Consider what an unexpected caller might learn through an ordinary-sounding conversation:
your full name;
where you work;
whether you’re looking for a job;
your email address;
your date of birth;
your bank;
or whether you’re expecting a particular payment.
Individually, some of those details may seem harmless.
Together, they can make a later approach more convincing.
For example, a completely generic message saying “there is a problem with your bank account” may be easy to dismiss.
A later caller who knows your name, knows which bank you use and knows that you’ve recently applied for a loan can sound much more credible.
That’s why Ofcom’s advice is straightforward: if you suspect a call may be fraudulent, hang up and don’t provide personal or financial information.
You don’t need to prove that a caller is a scammer before ending an uncomfortable conversation.
You can simply hang up and verify the claim yourself.
What to Do With a Suspicious Call in the UK
If an unfamiliar call rings briefly and leaves no meaningful information, don’t automatically call it back.
If you answer and hear a suspicious automated job offer, don’t follow its instructions simply because you’re currently looking for work.
And if a caller asks for personal information, payment details or an immediate transfer, stop the conversation.
Ofcom advises UK mobile customers to report suspicious calls to 7726. The number spells SPAM on a traditional telephone keypad, which can make it easier to remember. Reporting suspicious calls helps mobile providers investigate numbers being used for scam activity.
The precise reporting process can vary slightly between mobile providers, so follow your provider’s instructions if necessary.
Blocking the number can also stop that particular number from calling you again, although it doesn’t guarantee that the same criminals won’t try another number.
Most importantly, don’t engage merely to confront the caller or find out how the scam works.
Once you’ve recognised enough warning signs to distrust the call, continuing the conversation provides little benefit.
What If You Already Called Back or Shared Information?
Calling an unfamiliar number back doesn’t automatically mean you’ve been scammed.
What you do next depends on what happened during the conversation.
If you called back but gave no personal information, made no payment and didn’t follow any instructions, end contact and check your telephone bill if you’re concerned about the cost of the call.
If you shared information, consider exactly what you revealed.
Giving somebody your name and email address creates a different level of risk from giving them online-banking credentials or card information.
If you provided financial details or authorised a payment, contact your bank or payment provider immediately using an official channel.
Don’t use a telephone number supplied by the suspicious caller.
If you’ve lost money, prompt action matters because your bank may be able to take steps that aren’t available after significant time has passed.
Also watch for follow-up scams.
Someone who already knows you responded once may try again with a more convincing story. A second caller could even claim to be helping you recover money lost to the first scam.
Treat any unexpected follow-up contact with the same verification process.
A Simple Rule for Unexpected Calls
You don’t need to memorise every scam currently circulating in the UK.
The stories change.
Today it may be an automated job offer.
Tomorrow it could be a missed delivery, unpaid bill, tax refund, bank security alert or another believable reason to demand your attention.
The useful habit remains the same:
An unexpected caller doesn’t get to decide how quickly you act.
If a call feels suspicious, end it.
If the claim might be genuine, verify it independently.
If a missed call provides no context, don’t assume you need to call it back.
If someone claiming to be an employer wants money or sensitive financial information before you’ve even established that the job exists, stop.
And if somebody pressures you to ignore your doubts because the situation is urgent, treat that pressure as another reason to slow down.
Ofcom’s latest warning is useful precisely because the scams themselves are simple. They don’t necessarily require sophisticated technology or an elaborate story.
Sometimes all a criminal needs is for curiosity to make you return one unexplained call.
