020 4571 Dialing Code


Dialing Code 020 4571 is part of Area Code 020, which covers London and the surrounding area.

The majority of numbers in the 020 Area Code belong to normal landlines in London, but it is possible that these numbers are being used elsewhere as virtual numbers.

There are multiple telephone companies operating in the 020 Area Code and they are allocated blocks of numbers, which can be identified by the digits following the Area Code. In this case, the digits 4571 after the area code indicate that the range of numbers was originally allocated to Voxbone SA on 16 September 2021, although due to number portability, individual numbers within this range may now be allocated to other operators.
