0121 507 Dialing Code
Dialing Code 0121 507 is part of Area Code 0121, which covers Birmingham and the surrounding area.
The majority of numbers in the 0121 Area Code belong to normal landlines in Birmingham, but it is possible that these numbers are being used elsewhere as virtual numbers.
There are multiple telephone companies operating in the 0121 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 507 after the area code indicate that the range of numbers was originally allocated to BT on 15 July 1994, although due to number portability, individual numbers within this range may now be allocated to other operators.
