How scams that copy market research and surveys work
Genuine research firms do call people, which is why their numbers are worth checking. If a "survey" call asks for your bank details, a payment or a code sent to your phone, hang up.
Ofcom says scammers can fake the number that appears on your phone, which is called spoofing, and that they imitate UK numbers to look like a trusted person or organisation. Knowing details about you does not make a caller genuine.
This could still be a scam call
Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call In-house Research back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
