Where 028 is
One code covers all of Northern Ireland. The dot is Belfast; the local number, not the code, tells exchanges apart.
Could it be someone you know?
A number showing 028 might look familiar. Check the full number before trusting the caller. It can help to think whether you know someone in or around Northern Ireland, Stranraer or New Luce, have used a business there, booked or applied for something nearby, or are expecting a callback.

Does 028 tell me who called?
No. 028 is assigned to Northern Ireland, but that doesn’t prove who is calling or where they are. Caller ID can be faked, a number keeps its code when it moves provider, and 137 phone companies hold ranges of 028 numbers. Search the full number to see what people have reported about it and which phone company its range was given to.
Caller says they’re your bank, HMRC, the police or a courier? Hang up and call a number you trust, from your card, a letter or their website, or dial 159 for most UK banks.
Ofcom keeps 028 9649 6000 to 028 9649 6999 for TV and film. Those numbers can never connect, so if one called you, the caller ID was faked.
