Developer Preview Numbers
We’re constantly adding new local, mobile, and toll-free phone numbers from around the world. You can now get early access to the latest numbers being added to Twilio before they’re available via the Console or API. Find all Preview Numbers.
We are growing between 2,000 to 5,000 phone numbers a month and our previous vendor couldn't keep up with the volume of numbers.
Port your existing U.S. numbers from the current provider to Twilio through an online application, and we take care of the rest. You can also automate the porting process with the Twilio Porting API. Access developer preview.
If your carrier supports call forwarding over SIP, you can also use the Voice API with existing phone numbers. It’s a relatively inexpensive option for countries where Twilio doesn’t have phone numbers or where porting is not possible. See an example.
