Yes, there is a simple way to get the GA4 Measurement ID. You can use the Google Tag Assistant, a free Chrome extension, to quickly find this information. Once installed, browse to the website you want to get the GA4 Measurement ID from and simply click the Tag Assistant icon. It will display all Google tags found on the site, including Analytics, Google Tag Manager, and others. Then find the Google Analytics 4 tag mentioned in the displayed list and click on it, your GA4 measurement ID will be visible there. Note that it usually starts with “G-“. Keep in mind, however, that this method works only if the website does not block or restrict the visibility of these tags.
