The GA4 Measurement ID is a unique identifier assigned to each data stream in Google Analytics 4. It is a critical link connecting your website to the corresponding data stream in your GA4 account. This is important because it ensures the accurate tracking and analysis of data within your analytics account.

A data stream is a crucial component of GA4 that enables the collection and analysis of data from various sources, such as websites, mobile apps, and other digital platforms. It acts as a link between customer touchpoints and your GA4 property, allowing you to effectively track user interactions, events, and conversions.

In GA4, you can have multiple data streams within a single property. This allows for a combination of up to 50 web and app data streams, with a limit of 30 app data streams per property. Setting up these data streams is crucial for customizing data collection to meet your specific tracking requirements. Each data stream is dedicated to a particular source, ensuring accurate tracking of user interactions on that platform.

There are three types of data streams in GA4: web, Android, and iOS apps. These represent the different platforms from which you can collect user data. For example, if you want to track your website’s user interactions, you would select a web data stream. Within a property, you can have a combination of these data streams. When you create a data stream, it is given a Measurement ID, which is different from the Property ID which can be found in the property settings section. It’s essential to note this distinction between the two IDs. Now that we have established what a measurement ID, please follow the steps below to locate your GA4 Measurement ID:
