If you use a Chromebook regularly, knowing which version of ChromeOS you’re running is more important than it might seem. Your ChromeOS version determines which features are available to you, how secure your device is, and whether your Chromebook is still eligible for future updates. Whether you’re troubleshooting an issue, following a guide, or simply curious about the latest features, checking your ChromeOS version only takes a few seconds once you know where to look.
In this guide, we’ll walk you through the easiest and most reliable ways to check your ChromeOS version, explain what the version numbers actually mean, and show you how to confirm whether your device is fully up to date.
How to Check Which Version of ChromeOS You’re Running
Before jumping into the steps, it helps to understand why this matters. ChromeOS updates are rolled out gradually, which means not every Chromebook receives new features at the same time. Additionally, certain Android and Linux features are only available on specific ChromeOS versions. That’s why knowing your exact version can save you time and confusion when troubleshooting or following tutorials.
Let’s take a look at the different ways you can check your ChromeOS version.
1. Using Settings
This is the most straightforward and beginner-friendly method, and it works on all Chromebooks.
1. Click the time in the bottom-right corner of your screen to open the Quick Settings panel.
2. Click the gear icon to open Settings.
3. In the left sidebar, scroll down and select About ChromeOS.
4. On the About ChromeOS page, your current ChromeOS version number will be displayed at the top. You’ll also see details such as your update channel and whether any updates are available.
If an update is pending, ChromeOS will usually notify you immediately and provide a Restart button to complete the installation.
2. Using the Chrome Browser
There’s also a browser-based method that many users prefer, especially if they want quick access without opening Settings.
1. Open the Chrome browser on your Chromebook.
2. Type the following into the address bar and press Enter: chrome://system
3. You’ll be taken to the About System page, where you can view detailed system information about your Chromebook, including ChromeOS-related data.
This method is especially useful if you’re already working in the browser and want a fast shortcut to system details.
Understanding ChromeOS Version Numbers
When you check your ChromeOS version, you’ll see a number that looks something like this: Version 143.0.7499.196
At first glance, this may look confusing, but the most important part for most users is the main version number (for example, 143). This represents the major ChromeOS release you’re currently running. Higher numbers indicate newer versions with updated features and improved security.
The remaining numbers refer to minor updates, bug fixes, and security patches. In most cases, you don’t need to worry about these unless you’re troubleshooting a specific issue.
How to Check If Your Chromebook Is Fully Up to Date
On the About ChromeOS screen, you’ll also find a Check for updates option. Clicking this forces your Chromebook to look for the latest update available for your specific device.
If your Chromebook is already up to date, you’ll see a confirmation message. If an update is available, ChromeOS will download it automatically in the background and prompt you to restart your device to apply the changes.
Keep in mind that updates are rolled out in stages, so even identical Chromebook models may not receive updates at exactly the same time.
Wrapping Up
That’s really all there is to it. Checking which version of ChromeOS you’re running is quick, simple, and surprisingly useful once you make it a habit. Whether you’re following a troubleshooting guide, testing new features, or making sure your Chromebook stays secure, knowing your ChromeOS version puts you one step ahead.
If you ask us, this is one of those small checks that can save you a lot of time and confusion—especially as ChromeOS continues to evolve with every update.
