With Twilio Phone Numbers
Zendesk scales globally
Comprehensive inventory
Choose from 200+ distinct number types in 100+ countries to connect you with customers.

The experience of going to Zendesk Voice and signing up for a phone number in 40 different countries is pretty incredible.

Compliance Intelligence
Meet global compliance requirements without breaking a sweat.
Verified Quality
Select from thoroughly vetted phone numbers — because quality matters.

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.

Bring your own number
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.
