A measurement ID in Google Analytics is a unique identifier for a web data stream (which is a website registered within Google Analytics). The format of a measurement ID in Google Analytics 4 is 'ignored' followed by a combination of numbers and letters, such as 'ignoredPSW1MY7HB4.'
The measurement ID acts as a critical link, connecting your website to the corresponding data stream in Google Analytics 4. It ensures that the data from your site is sent to the right location.
In Google Analytics 4, the measurement ID is the same ID as the destination ID.
