Developer preview phone number availability

As we expand Twilio’s coverage through partnerships with new service providers, we go through a rigorous performance and reliability testing process of new numbers. Before we make new numbers available to all customers through our Beta program, we work with key customers to help us test new numbers in the real world, with real applications.

We have vetted these numbers and don’t expect you’ll have problems should you choose to try one out, but you should be aware that occasionally this testing phase reveals issues that we cannot detect in our test labs. Please keep this in mind as you deploy these numbers as part of your application. It is not advisable to use these for critical path or production systems until we have more experience with the numbers and are able to put them into Beta. Please also note that on rare occasions some numbers don’t successfully pass the alpha stage and need to be discontinued from service. Should any issues arise, you can expect the same level of support and responsiveness that you’ve come to expect from Twilio.
