Top‑tier phone numbers
Build with confidence, knowing that every Twilio Phone Number goes through extensive testing, including technical evaluation, capability testing, and traffic monitoring.
First‑rate routes
When it comes to voice quality and SMS deliverability, the network behind the number is everything. Twilio meticulously tests every network provider so you don’t have to.
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.
Number Porting
Port your existing numbers to Twilio through an online application or email and then we take care of the rest. For complex use cases, we offer custom porting services so you can have a dedicated expert to manage and execute your port-in.
SIP Forwarding
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 isn’t possible.
