Who called you from 028?
A call from an 028 number is a call from a number registered to the Northern Ireland / Ballycastle / Martinstown area. That could be a local business, a GP surgery, a school, or a call centre that bought local numbers to look local. Ofcom's allocation data tells you which phone company issued the number, and that's the most anyone can tell you from the number alone.
Which companies hold 028 numbers
Ofcom allocates numbers to phone companies in blocks. These are the operators holding the most 028 blocks. The company that was issued a number often supplies it onward to a business or reseller, and UK numbers can be ported between networks, so read this as where the number started, and a strong hint rather than proof of who serves it today.

| BT | 349 | 11% |
| GCI Network Solutions Limited | 321 | 10% |
