Verify SNA Live Test Number


The Verify Silent Network Auth (SNA) Live Test Number feature allows developers to quickly test and experience Silent Network Authentication using their own mobile number, without first obtaining carrier approvals that can take 2-4 weeks.


  • Developers can currently test their mobile numbers on supported carriers in these countries: United States, United Kingdom, France, Spain, and Germany. Once your Twilio account is enabled to use SNA, you can access this list of Live Test Number supported carriers within each country. Note that the page will appear broken unless you are logged in to an account that has SNA enabled.
  • Note that the countries/carriers available for Live Test Number is a subset of what is available once your company is approved via the 2-4 week carrier approval process.
  • If your mobile number isn’t in one of the supported countries, you can use a third-party mobile device testing service like Headspin to obtain one. See our Verify SNA Headspin Testing Guide for more details.
  • The general limitations of Verify SNA also apply.
