Who called you from 01257?
A call from an 01257 number is a call from a number registered to the Coppull area. That could be a local business, a GP surgery, a school, or a call centre that bought local numbers to look local. Ofcom's allocation data tells you which phone company issued the number, and that's the most anyone can tell you from the number alone.
Which companies hold 01257 numbers
Ofcom allocates numbers to phone companies in blocks. These are the operators holding the most 01257 blocks. The company that was issued a number often supplies it onward to a business or reseller, and UK numbers can be ported between networks, so read this as where the number started, and a strong hint rather than proof of who serves it today.
