[GA4] Find your Google tag ID

Use the Google tag ID for Google Analytics 4 properties (vs. the Tracking ID for Universal Analytics properties).

To set up a Google Analytics 4 property for your website, you need a Google tag ID (which usually starts with "G-").

Google tag ID vs. Tracking ID
Google Analytics 4 is our next-generation measurement solution, and it has replaced Universal Analytics. Universal Analytics properties used a Tracking ID (which starts with "UA-"), but Google Analytics 4 properties use a Google tag ID (which usually starts with "G-").

To set up a new Google Analytics property, you do not need a Tracking ID.

Find your Google tag ID

To find your Google tag ID (which usually starts with "G-"), do the following:

  1. Sign in to your Google Analytics account.
  2. In Admin, under Data collection and modification, click Data streams.
  3. In the Google tag section at the bottom of the Web stream details page, click Configure tag settings.

  4. In the Your Google tag section on the Google tag page, copy the ID that starts with "G-" or "AW-".

Find your "UA-" ID

You do not need a Tracking ID ("UA-" ID) to set up a new GA4 property. Only (legacy) Universal Analytics properties have a "UA-" ID.
  1. Click Admin in your Universal Analytics property.
  2. In the Property column, click Property Settings.
  3. Your "UA-" ID appears at the top of the Property Settings page.
