After you submit an order to add dedicated 8XX numbers, you can use the Dedicated Toll Free Origination (DTFO) tool (in Control Center) to make changes to the numbers. In Control Center, you can submit and manage orders for TDM dedicated and IP voice toll-free numbers. New/reserved, porting, and complementary-carrier order types are supported. Other 8XX ordering options in Control Center include self-service tools and online order forms (OLOFs).
Before you start, review DTFO basics and ordering requirements.
