Who called me from 01833?
The prefix tells you where the line was originally registered (Barnard Castle), 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.
