Numbers in blocks like (028) 27524 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) 27524 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. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
