Google Analytics 4 (GA4) transformed how businesses track and quantify user behavior. Compared to Universal Analytics, GA4 employs an event-based model focused on user action rather than session-based tracking. The Client ID is among the critical aspects in GA4, and it serves to track unique users and their interactions between sessions. Understanding information with Client ID and Google Analytics 4 helps businesses gain deeper insights into user behavior and optimize their tracking strategies.
Knowing how Client ID works and how to get it in GA4 can indeed improve user experience, marketing relationships, and customer segmentation. This article is therefore comprehensive on information with Client ID and Google Analytics 4 such as what the term means, how to get it, and how to use it effectively for data analysis.
What is a Client ID in GA4?
Client ID is a single-use unique number assigned randomly to a given user upon their very first visit to a site. It is kept in a browser cookie and is that number as long as the user’s cookies are not deleted or used in an incognito mode. Henceforth every time that same user visits the site, GA4 recognizes that user by the same Client ID, allowing better tracking of user flows. Unlike User ID, which needs to be implemented manually and is meant for logged-in users only, Client ID works automatically with visitors. That is why it becomes an important means of tracking user actions where users never log into a website or application.
How Does Client ID Work in Google Analytics 4?
When a user comes to a site, GA4 creates a Client ID and places it in a first-party cookie called _ga. This ID does not change across sessions except in cases where the user deletes cookies or the user comes to the site from another browser or device.
Every time an event is triggered – like a view, click, or form submission – GA4 logs the Client ID together with the event details. This allows companies to examine user behavior, monitor repeat visitors, and gauge session engagement over time.
Client ID plays a crucial role in cross-device tracking. However, since it relies on cookies, it has limitations when users switch devices or browsers. If a visitor uses both a desktop and a mobile device, they will be assigned different Client IDs unless a User ID system is in place.
Why is Client ID Important in GA4?
Client ID tracking and Google Analytics 4 is critical for businesses to gain insight into user behavior, optimize their marketing campaigns, and enhance site performance. Following are the top reasons why Client ID plays an important role in GA4:
User Behavior Analysis

How to Get Client ID in GA4
GA4 does not show Client ID in regular reports, but it is retrievable through JavaScript, Google Tag Manager (GTM), or BigQuery.
Using JavaScript within the Browser Console
One of the simplest methods to retrieve Client ID is by using JavaScript. Putting the following code within the browser console will log the Client ID assigned to the present session:
gtag(‘get’, ‘GA_MEASUREMENT_ID’, ‘client_id’, (clientID) => {
console.log(‘Client ID:’, clientID);
});
Replace GA_MEASUREMENT_ID with your own GA4 property ID. This method is useful when debugging and verifying Client ID values.
Using Google Tag Manager (GTM)
Google Tag Manager makes it possible for businesses to collect and save Client ID as a user property. To implement this method:
Go to Google Open Google Tag Manager and add a new Custom JavaScript Variable.
- Manager and create a new Custom JavaScript Variable.
- Add the following code to get the Client ID:
function() {
return new Promise((resolve) => {
gtag(‘get’, ‘GA_MEASUREMENT_ID’, ‘client_id’, resolve);
});
}
- Set this variable as a User Property in GA4.
- Construct an event tag to push Client ID into Google Analytics as a custom dimension.
This method allows businesses to better track users and report on Client ID data.
Retrieving Client ID via BigQuery
For deeper analysis, companies can retrieve Client ID data in BigQuery, which maintains raw GA4 event data. If BigQuery is connected with GA4, retrieve Client ID using the following SQL query:
SELECT user_pseudo_id, event_bundle_sequence_id, event_name, event_timestamp
FROM `your_project.analytics_XXXXXX.events_*`
WHERE event_name = ‘session_start’
This process is apt for companies requiring analyzing large data sets, observing user journeys, and conducting granular segmentation.

Challenges and Drawbacks of Client ID in GA4
Client ID, though a rich resource for monitoring user activity, has some drawbacks:
- Cookie Limits – If the user deletes the cookies, they are no longer given a Client ID, so it is difficult to track them on their second visit.
- Cross-Device Tracking Challenges – Because Client ID is browser-based, it does not track users across devices by default. Using a User ID system can correct this problem.
- Privacy Regulation – With rising privacy regulation such as GDPR and CCPA, businesses need to fall in line while gathering and measuring Client ID information.
- No GA4 Simple Reporting – Unlike Universal Analytics, there is no easy reporting feature available in GA4 for viewing Client ID data, so a user has to carry out an extra step or two to get their hands on it.
Despite these challenges, learning about the information with client ID and Google Analytics 4 is important for businesses that want to improve their marketing and analytics.
