“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.”
Own numbers
Bring your own numbers
Add Twilio SMS and Voice capabilities to your existing landline or mobile number.
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.
Hosted Numbers
Enable SMS, Voice, MMS, and Fax with your existing phone number without changing your voice service.
