Most phones let you see the number of the person calling before you answer, but there've been more and more instances when callers and criminals deliberately change their caller ID. This is what we call spoofing.
Sometimes there's a good reason for a caller to modify the Caller ID, like leaving an 0800 number for the customer to call back, but spoofing callers do this to hide their identity or make you think it's a legitimate call.
For example, identity thieves looking to steal sensitive information such as your bank account or login details might use spoofing to make it look like your bank or credit card company is calling.
Ofcom is working with the international regulators and the telecoms industry to put a stop to spoofing, so don't worry – we're fighting it!
What you can do
Identity thieves and other fraudsters often pose as representatives of banks, credit card companies, creditors, or government departments to get people to reveal their account numbers and other sensitive information.
Never give out personal information on an incoming call, and don't rely on caller ID to identify a caller, especially if they claim to be from someone like your bank.
Hang up the call and call the company back using their official details – maybe check your account statement or the company's website – to find out if the call was genuine. Try to wait at least 5 minutes before you do this to make sure the line clears and you're not contacting fraudsters.
