Introduction to measurement ID in GA4

In order to set up any type of tracking in GA4 via GTM, you would need to use the measurement ID. This makes understanding the measurement ID so important.

Google Analytics 4 uses measurement ID instead of tracking ID like in Universal Analytics. The measurement ID format is G-XXXXXXX and it identifies which data stream is sending data to your GA4 property.

If you have set up a GA4 property with a web data stream, then your Google Analytics measurement ID begins with the characters ‘G-’. 

For example, G-SV0HS12BXZ

Difference between Measurement ID and Property ID

The measurement ID is not the same as the property ID. Measurement IDs are the identifiers of data streams. Data Streams in Google Analytics 4 are the flow of data from customer touchpoints to Analytics and it can be a mobile application or a website.

Each Google Analytics 4 property can contain up to 50 data streams. So, for example, you can send data from your mobile app which has its unique measurement ID, and a website that also has its own measurement ID into one single GA4 property. You can correlate this with below image.

All GA4 properties have got property ID which you can find by following the steps below:

Step-1: Navigate to the ‘Admin’ section of your GA4 reporting view.

Step-2: Click on ‘Property Settings’ under the ‘Property’ column:

ga4 measurement id Property Settings ga4

You can now see the property ID on the right-hand side of your screen:
