In 2020 Google launched Google Analytics 4 (GA4; earlier called “Web + App”). The previous version of Google Analytics is called “Universal Analytics”, or just “Analytics”.

Currently, GA4 is the default version when creating a new tracking code.

How can I recognize the version of my GA?

The easiest way is a tracking code ID:

  • Google Analytics 4 (GA4) tracking code starts with the prefix “G-“ – e.g. “G-PSW1MY7HB4”
  • Universal Analytics tracking code starts with the prefix “UA-“ – e.g. “UA-54516992-1”

User interface is different as well…

Can I use Google Data Studio for GA4?

Yes. But you need a different Google Data Studio templates – one for Google Analytics 4 and another for Universal Analytics.
