Numbers in blocks like (028) 67242 XXX are sometimes spoofed by overseas call-centres using VoIP. Spoofing makes a foreign call appear to come from a UK landline — including the area code where you live. If you don't recognise the number and the caller asks for any personal data, hang up and call the organisation back on a number you know is genuine.
If a (028) 67242 XXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call.
