To find your Roblox user ID on mobile, you must use a web browser like Safari or Chrome, as the ID is not visible inside the Roblox mobile app. Your unique numerical User ID is located in the profile URL on the Roblox website, between "users/" and "/profile".
Why you can't find your Roblox user ID in the mobile app
The Roblox mobile app does not display your User ID anywhere in its interface. This is because the User ID is a fixed numerical code assigned by the system, distinct from your custom username. While your username is what others see in the app, the User ID is a permanent, unchangeable identifier used for backend functions. To access it, you must leave the app and log into the Roblox website through a mobile browser.
How to find your Roblox user ID on mobile using a browser
Follow these steps on your iPhone, Android, or iPad:
- Close the Roblox app if it is currently open.
- Open Safari or Chrome on your mobile device.
- Navigate to Roblox.com and log in to your account using your credentials.
- Once logged in, tap the three horizontal lines (menu icon) in the top-left corner of the screen, then select "Profile." Alternatively, you can tap your profile icon, typically found in the top-right corner, to access your profile page.
- Look at the address bar at the top of your browser screen. Your User ID is the large number located in the URL between "users/" and "/profile", for example, in
https://www.roblox.com/users/123456789/profile, the "123456789" is your User ID. The URL format may also appear as "user.aspx?id=" before the numerical ID, not just "users/". - Tap and hold the numerical ID in the address bar to select and copy it for later use.
What to do if the address bar is hidden
On some mobile devices, the full URL may not be visible by default. If the address bar is hidden, try tapping the lock icon near the address bar, or pull down on the page to reveal the full URL. If these don't work, tap the share button on your profile page, choose "Copy Link," then paste the URL into a notes app. You can then extract the User ID from the pasted link. As a last resort if you cannot find your ID using the browser method, try contacting Roblox Customer Support.
Why your Roblox user ID matters and how to keep it safe
Your Roblox User ID is essential for account identification, contacting Roblox support, trading items, joining specific game servers, and for developer tools. Because it is a permanent number that cannot be changed, it is recommended to keep your User ID private and not share it publicly. Treat it like a sensitive account detail. For additional "Roblox mobile help" (Roblox on Mobile: Setup, Fixes and Gameplay), consult the official Roblox support resources within the app.
