What is a Call SID?

When a voice call is successfully placed, Twilio will assign it a unique ID that we refer to as a Call SID. A Call SID is an important troubleshooting resource to provide Twilio support when you report a voice-related issue.

You can find the SID for a call one of two ways:

1) By looking at the call log in the console:

Log into your Twilio project and navigate to Logs -> Calls, and click a call of interest to bring up the correct details.

The call SID is the first item displayed:


2) By making a REST API request to the Calls List Resource:

To find the SID for a specific call via the API, make a GET request to the call list resource. This will return a list of calls associated with your project along with details about each message.
