Vonage Porting Instructions
Porting in is possible, but it may take up to 10 business days. Porting out requires the customer to call Customer Service and ask for their account number and transfer PIN. There may be an issue porting in or out of Vonage due to “geographical limitations.” The rep we spoke to would not elaborate further.
Vonage provides VoIP (Voice Over IP) service for business and personal accounts. Our rep received very poor assistance from Vonage when they called, with a foreign operator who spoke harshly.

Check coverage before you port
We have not confirmed which national network Vonage uses, and we do not guess. Ask them before you port, then check that network’s map: Verizon, T-Mobile, AT&T.
Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.
Working a counter? The Vonage transfer PIN lookup puts these steps on one screen and texts them to the customer.
