Ofcom has allocated this block of numbers to BT.
Ofcom allocates phone numbers to communications providers in blocks. The provider shown is the one Ofcom allocated this block to. It is not the person or business that called you, and the number may since have moved to a different network, because people can usually keep their number when they switch provider. Ofcom does not hold information about individual numbers.
