Can customers retain their existing BT numbers?
This can depend on the exchange, but in most cases, yes. An industry process exists which mandates BT to allow this transfer of numbers to happen. Alternatively a customer may select a non geographic number (for example a 0800 number), or a geographic number associated with a desired ‘virtual location’, such as London. This is ideal for organisations wishing to portray a presence in the capital (or anywhere else for that matter!) but who are located elsewhere.
