Verify Silent Network Auth Testing Guide
Verify Silent Network Auth (SNA) allows you to confirm user possession of a mobile phone number without explicit user intervention by communicating directly with mobile carriers. Learn more about how it works with SNA Overview, SNA API Reference, and What is Silent Network Authentication? blog post.
In this guide, we will walk you through testing the entire SNA process step-by-step on your own mobile device without having to make any modifications to your mobile app.
- Create a Twilio Account
- Note your Account SID and Auth Token from the Console .
- Request access to the API and Live Test Number feature. If there are no issues, access will be granted within 24 business hours.
- Create a Verify Service
- Note your Service SID from the Verify Services tab in the Console .
- You will need to use a smartphone associated with an approved carrier (e.g. an iPhone with a Verizon Wireless phone number)
You also have the option to test SNA without carrier approval or a valid Live Test Number. In this testing flow, use Twilio Region US1 for your requests to Start a New SNA Verification for any mobile number and Invoke the SNA URL as described in this guide. Note that requests made to regions outside US1 in this testing flow will fail. When you reach the Check the Verification Attempt result step, you will receive an expected error code.
To begin, use the Start New Verification endpoint with the parameter channel=sna to create a new SNA Verification.
Check your response from the Start New Verification endpoint for the sna.url property. The SNA URL is unique for every Verification Attempt, has a default time-to-live of 10 minutes, and can only be processed once. Once it has been called, it will not be valid anymore.
Note its value for use in the next step:

You can invoke the URL by sending it to yourself through either email or Slack following the *special instructions* below.
Copy and paste the SNA URL and send it to yourself via email.
