029 is the area code for Cardiff, the capital of Wales, and its immediate surroundings such as Penarth. It replaced 01222 in 2000; local numbers have eight digits and Cardiff numbers traditionally begin 20, 21 or 22. Calls from 029 numbers often come from Welsh Government offices, Cardiff Council, NHS Wales bodies, the city's universities, media companies and local firms. Numbers can be ported to other networks or used on internet phone systems anywhere, and the caller ID shown can be faked, so treat an unexpected call from an 029 number with the same care as any other unknown caller.
Who called me from 029?
The prefix tells you where the line was originally registered (Cardiff), but not who is behind it. Numbers can be ported between networks and caller ID can be spoofed, so a familiar code is no guarantee. Search the full number to see its current carrier, line type and whether other people have reported it.
