Your computer name is the identifier your device uses on a network

Your computer name (also called a hostname or device name) is a label that identifies your machine on a network or when you're troubleshooting problems. It's different from your user account name — the name you log in with. You might need your computer name to connect to a printer, join a work network, get technical support, or transfer files between devices.

The steps to find it depend on whether you use Windows, Mac, or Linux. Each operating system stores this information in a different place, but it takes less than a minute to locate on any of them.

Key Takeaways

  • Your computer name is a network identifier separate from your login username, and you may need it for printers, file sharing, or tech support.
  • On Windows, right-click "This PC" or "My Computer" and select Properties to see your computer name immediately.
  • On Mac, open System Settings, go to General, then About to find the computer name listed as "Computer Name."
  • On Linux, open a terminal and type hostname to display your computer name.

Finding your computer name on Windows

The fastest way on Windows is through the Properties window. Right-click on "This PC" (Windows 10 and 11) or "My Computer" (Windows 7) on your desktop or in File Explorer. Select Properties from the menu that appears. Your computer name will be listed under "Computer name" near the top of the window.

If you don't see a desktop icon, open File Explorer, look for "This PC" in the left sidebar, right-click it, and choose Properties. The same information appears in the same location.

You can also find it through Settings. Open Settings, go to System, then About. Scroll down to find "Device name" — this is your computer name. This method works the same way on Windows 10 and Windows 11.

Finding your computer name on Mac

On Mac, open System Settings (called System Preferences on older versions). Click General in the sidebar, then click the About button. Your computer name appears at the top of the window next to "Computer Name."

If you're using an older Mac with macOS Big Sur or earlier, the steps are slightly different. Open System Preferences, click Sharing, and look at the field labeled "Computer Name" at the top of the window. This is your device identifier on the network.

You can also find this information in the Finder. Click the Apple menu in the top-left corner, select About This Mac, and your computer name appears in the window that opens.

Finding your computer name on Linux

On Linux, the quickest method is through the terminal. Open a terminal window and type the command hostname, then press Enter. Your computer name displays immediately on the next line.

If you want to see more detailed information, type hostnamectl and press Enter. This shows your hostname along with other system details like operating system and kernel version. Both commands work on most Linux distributions including Ubuntu, Fedora, and Debian.

What to do if you see an unfamiliar computer name

If your computer name looks random or contains numbers and letters that don't match anything you recognize, this is normal. Manufacturers often assign default names like "DESKTOP-ABC123" or "MacBook-Pro-2024." You can change your computer name if you want something more meaningful, though this is optional and won't affect how your computer works.

If you're on a work or school network and the name looks wrong, contact your IT department. They may have assigned a specific name for network purposes, and changing it could cause connection problems.

Why you might need your computer name

Your computer name becomes important when you're setting up a network printer — the printer's setup screen often asks for it. It's also needed when you're connecting to a shared folder on another computer, troubleshooting network problems with tech support, or joining a workplace domain. Some software installation processes ask for it as well.

When you call technical support for any device issue, have your computer name ready. Support staff often ask for it to help narrow down what's happening and to look up your device history if you've contacted them before.

Frequently Asked Questions

Is my computer name the same as my username?

No. Your username is what you type to log in to your account. Your computer name is a separate identifier for the entire machine. You can have multiple user accounts on one computer, but there's only one computer name.

Can I change my computer name?

Yes. On Windows, right-click This PC, select Properties, then click "Rename this PC." On Mac, go to System Settings > General > About and click "Edit" next to Computer Name. On Linux, use the hostnamectl set-hostname command in the terminal. Changes take effect after you restart.

What if I can't find my computer name using these steps?

Make sure you're looking in the right place — Properties on Windows, About on Mac, or terminal on Linux. If the window looks different, you may be using an older version of your operating system. Check your OS version first, then adjust the steps accordingly.

Do I need my computer name to use the internet?

No. Your computer name only matters for local networks and when connecting devices like printers. Regular internet browsing works without it. You only need it when troubleshooting network problems or setting up shared devices.
