Usually when you move home you will not be able to keep your old phone number.
The only exception is if you’re moving to a new home within the same telephone exchange area.
Keeping your number in this case isn’t always guaranteed, but most telephone and broadband providers will be happy to help whenever it is possible.
There are over 5,500 telephone exchanges in the UK.
If you are moving to a different telephone exchange area, then your home phone number will almost certainly have to change.
Residential phone numbers in the UK are tied to physical locations through area codes, so your phone number has to reflect the area that you live in.
