About BT in the Ofcom register
BT is one of the UK communications providers allocated number ranges by Ofcom under the National Telephone Numbering Plan. Number allocations are recorded against the legal entity BT. Numbers within those ranges may now be in active use by the original allocated subscriber, may have been ported to another carrier under UK number portability rules, or may have been re-issued after being returned to the operator's pool — so the Ofcom range holder is not a guarantee of the current call source.
