You must port over the entire number block. An Administrative Fee will apply to all numbers you are porting over. If you do not require all numbers going forward you can notify Blueface of the numbers you wish to port and remain active and those you wish to port and cease. Ceasing numbers you do not wish to use going forward will prevent any ongoing charges for unused numbers. Please review the numbers carefully to ensure that you do not cease any numbers which are advertised to your customers.
