How to Find Google Analytics 4 Property ID
Trying to connect a new tool or service to Google Analytics 4 and getting stopped by a field asking for a "GA4 Property ID"? You’re not alone. While the Measurement ID (G-XXXXXXXXXX) is easy to spot, the Property ID is a bit more tucked away. This guide will show you precisely where to find your GA4 Property ID in just a few clicks and explain why it's a critical piece of information for a variety of tasks.
What Is a GA4 Property ID, Anyway?
Think of your Google Analytics account as a filing cabinet. Inside that cabinet, each portfolio is an "Account," which usually represents your business. And inside each portfolio, you have folders, which are your "Properties." A property typically corresponds to a website, an app, or a group of related websites/apps whose data you want to analyze together.
The GA4 Property ID is a simple, unique numerical identifier assigned to your GA4 property. It’s a string of numbers (e.g., 123456789) that GA and other services use to unambiguously identify that specific property.
It acts like a backend serial number, primarily used for integrations that need to ask for data from your property, such as connecting to BigQuery, using the GA Data API, or plugging into third-party reporting and data visualization tools.
This is different from the much more common Measurement ID (e.g., G-ABCDE12345), which is used to send data to your property from a specific source, like your website or mobile app.
How to Find Your GA4 Property ID: A Step-by-Step Guide
Locating your Property ID is simple once you know where to look. It’s hidden within the Admin settings. Here’s the fastest way to get there:
Step 1: Navigate to the Admin Section
Log in to your Google Analytics account. Once you’re on the main dashboard, look for the gear icon labeled "Admin" in the bottom-left corner of your screen and click on it.
Step 2: Ensure the Correct Account and Property Are Selected
The Admin page has two columns: "Account" and "Property." In the "Account" column, make sure you have the correct account selected from the dropdown menu.
Next, in the "Property" column, verify that you have selected the correct GA4 property. If you have multiple websites or apps, they will each have a different property. Toggling the correct one here is essential for finding the right ID.
Step 3: Open Property Details
With the correct property selected, simply click on "Property details" under the "Property" settings list. This is the first option at the top of the list.
Step 4: Find and Copy Your Property ID
You’re there! On the "Property details" page, your Property ID is displayed prominently in the upper-right corner. It’s a 9 or 10-digit number. You can click the small copy icon next to it to copy it directly to your clipboard.
That's it. You now have the unique identifier you need for your backend integrations and data connections.
Measurement ID vs. Property ID: Clearing Up the Confusion
One of the most frequent sources of confusion for GA4 users is the difference between the Property ID and the Measurement ID. They serve very different purposes, and using one where the other is required will cause your setup to fail. Let's break it down.
The Measurement ID (Format: G-XXXXXXXXXX)
The Measurement ID is all about data collection. It is specific to a single Data Stream (e.g., your website, your Android app, or your iOS app). When you add your GA4 tracking code to your website using Google Tag Manager or gtag.js, this is the ID you use. Its job is to tell the visitor's browser which specific data stream to send its activity information to.
Purpose: To send data into a specific data stream associated with your property.
Where you use it: In your website’s tracking code, Google Tag Manager tags, and other client-side data collection setups.
Where you find it: Admin > Property > Data Streams > [Select your stream].
The Property ID (Format: 123456789)
The Property ID is all about data integration on the backend. It identifies your entire GA4 property, not just one data stream. It’s used when you need to authorize another application or service to access or pull a copy of the data that has already been collected in your property. It essentially serves as a unique address for the entire property "folder."
Purpose: To identify the entire property when connecting to external tools, APIs, and services.
Where you use it: Third-party BI tools, reports, Google API connections, BigQuery links.
Where you find it: Admin > Property > Property details.
A Simple Analogy
Imagine your GA4 Property is an office building for your company's data.
The Property ID is the primary mailing address for the entire building. You give this to services like the post office (BigQuery) or utilities (API services) so they know where to interact with the entire building.
Each Data Stream (website, iOS app) is a different entrance to the building.
The Measurement ID is like the sign on one specific entrance (e.g., "Main Lobby" or "Loading Dock"). It directs incoming traffic (website visitors) to the correct door so their data can get inside.
You wouldn't direct package deliveries to a specific door sign, you'd give them the building's main address. Similarly, you use the Property ID when you need another service to connect to your data holistically.
Common Scenarios for Using Your GA4 Property ID
You may not need your Property ID every day, but it’s critical for several high-value tasks that unlock deeper insights from your analytics data.
Connecting to Google BigQuery: To perform a raw data export from GA4 into BigQuery for advanced SQL analysis, you need to use the Property ID to establish the link.
Using the Google Analytics Data API: If you're building a custom dashboard or application that pulls data from GA4, your code will use an API call which specifies the Property ID as the source.
Third-Party Integrations: Many external reporting dashboards, BI tools, and data connector services will specifically ask for your Property ID during the setup process to authenticate and pull your marketing and website data.
Auditing and Management: For businesses with dozens of web properties, using the numerical Property ID is the most reliable way to confirm you're working with the right asset, preventing misconfigurations.
Troubleshooting: Can't Find Your Property ID?
If you're following the steps but still can't find your ID, one of these common issues might be the cause.
1. Insufficient Permissions
To view the "Property details" page, you need to have, at minimum, the "Viewer" role assigned at the Property level. If you can only see limited options in the Property column and "Property details" is missing, you likely don't have the necessary access. Contact an administrator for your company’s Google Analytics account and ask them to grant you Viewer access to the property.
2. You're Mistakenly Looking at a Universal Analytics Property
Google officially sunsetted Universal Analytics (UA) in 2023, but many old properties still exist in Google Analytics accounts. UA properties use a "Tracking ID" (formatted as UA-XXXXX-X), not a Property ID. If you navigate to Admin and see a "Tracking Info" section instead of "Data Streams," you're in a UA property. Make sure you've selected the correct GA4 property from the main property dropdown selector.
3. The Incorrect Account or Property Is Selected
It sounds basic, but it's the most common mistake. Many users have access to multiple accounts (personal projects, clients, company properties). Always double-check that you've selected the intended Account and Property from the dropdown menus in the Admin section before you start digging through settings.

Remembering its role as the backend identifier for your entire property - distinct from the front-end Measurement ID used for data collection - empowers you to connect your GA4 data to a host of powerful external tools and services.
