About the 028 dialling code
028 is the UK area code for Northern Ireland and the surrounding Northern Ireland area, listed in Ofcom’s National Telephone Numbering Plan. When a UK landline calls you and the number begins +44 28 the originating exchange is most likely physically located in or near Northern Ireland. Numbers in this code are allocated to UK communications providers in 1,000- or 10,000-number blocks; the table below shows which Range Holder Ofcom assigned each block to.
This is the same data Ofcom publishes every Wednesday in the public UK Numbering Data feed. We re-ingest the snapshot weekly, so the allocations you see here are at most seven days old. Because UK numbers are portable, the current carrier of any specific number on 028 can differ from the Range Holder shown — see Range Holder vs current provider for the full explanation.

You will see the Range Holder, the allocation status, the area-code metadata for Northern Ireland, and a live AI internet check summarising any public web reports about that exact number — useful when an unfamiliar 028 caller turns out to be a legitimate local business, a national contact-centre, or a scam.
