What a 012183 number tells you

Watch out for

A local-looking number feels familiar, which is exactly why scammers spoof them. A local area code is not proof the caller is local.

The range holder isn’t necessarily the caller. Ofcom gives numbers to providers in blocks, and people and businesses can take their number with them when they switch. To find out who actually called, check the full number.
TV and radio numbers. Ofcom reserves 0121 496 0000 – 0999 for use in TV and radio drama, so the numbers you hear on screen don’t belong to real people.
