You can update more than one remote DID phone number at one time—including adding descriptions, so you can remember them more easily. If you need to modify large blocks of numbers, you can bulk upload your changes and save time.
To make bulk changes to DID numbers:
Control Center displays a list of all services assigned to the accounts under your enterprise ID. If you have more than ten services, you can view the rest of your services by clicking one of the green linked Show numbers at the top of the list or you can click the green down arrow at the bottom of the list to add ten services at a time to the view.
