Google Analytics needs measurement ID in its tracking code to determine which account and property to send data to.
Difference Between GA4 Measurement ID and Property ID
In GA4, your measurement ID is used to identify your data streams. You can get data from more than one source (like a website or mobile app) into the same property.
Each of your data streams will have a different measurement ID, but all of them will have the same property ID.
