Where Tracking IDs are used to identify the Analytics accounts and web properties you're sending data to, Measurement IDs are used to identify the web data streams you've added to send data to your App + Web properties.
Measurement IDs take the form G-XXXXXXXXXX.
Analytics generates the global site tag and the Measurement ID when you add an App + Web property and a corresponding web stream.
To see the global site tag for your website and the Measurement ID for a web stream:
- Sign in to Analytics.
- Navigate to your App + Web property.
- Click Admin.
- In the Property column, click Data Streams, then click Web, then click the row for the relevant data stream.
The Measurement ID is displayed at the top right.
The global site tag is displayed under Tagging instructions.
You can find the Tracking ID for an Analytics web property in Admin > Property column > Tracking info > Tracking Code.
