Two 03 ranges with their own page
Two 033 ranges have their own pages: 0330 numbers and 0333 numbers, each with the numbers people have reported under it. This page covers the rest of the 03 range.
Ofcom keeps 0306 999 0000 to 0306 999 0999 for TV and film. Those numbers can never connect, so if one called you, the caller ID was faked.
Call prices vary by provider and change over time. Ofcom’s call costs guide explains how every kind of UK number is charged. To see what people have said about one number, check it above.
