This article teaches you how to find your iPhone’s serial number, which serves as a unique identification code for your device. This number can be located in the Settings app on your iPhone, printed on the back of the device, or found on the SIM tray. If your iPhone is not accessible, you can also look for the serial number on the original packaging or on the accompanying receipt or invoice.

Before you start: Make sure you have your iPhone accessible or the original packaging or receipt, if needed.

How to locate your iPhone’s serial number

Follow these steps to find your iPhone’s serial number easily.

  • Open your iPhone’s Settings. You’ll usually find this icon on the home screen or in a folder.
  • If your iPhone is not working and you need your serial number for Apple support, you can use your IMEI/MEID number instead. This number is printed on the back of the phone (iPhone 5, 6, and SE) or on the SIM tray (6s and later, 3G, and 4).
  • Scroll down and tap General. It’s in the third group of settings.
  • Tap About. It’s at the top of the menu.
  • Find your iPhone’s serial number near the top of the menu. It’s next to “Serial Number,” which is at the bottom of the first section. If you need your CDN, IMEI/MEID, or ICCID, scroll down to the bottom of the menu.

Finding the serial number using iTunes

  • Open iTunes on your computer. If you’re using a Mac, it’s the multicolored music note icon typically found on the Dock. If you’re using Windows, you’ll find it on the Start menu and possibly on the desktop.
  • Connect the iPhone to the computer with a USB cable. Use the cable that came with your iPhone or one that’s compatible.
  • Click the iPhone button in iTunes. It’s near the top-left corner to the right of the Library drop-down menu. A small picture of your iPhone and a menu will appear in the left panel.
  • Click Summary in the left panel. It’s under the “Settings” header. This displays information about your iPhone in the right panel.
  • Find your serial number in the right panel. It’s the “Serial Number” entry inside the box at the top of the panel. If you need access to your CDN, IMEI/MEID, or ICCID number, click your phone number.

Finding the serial number on the packaging or receipt

  • Check the iPhone’s packaging and/or receipt. If you have the box that your iPhone came in, you’ll find the serial and IMEI numbers on the barcode sticker. The serial number may also be printed on a receipt or invoice.
  • If you ordered your iPhone online, you may find the serial number in a digital receipt.

Finding the serial number via Apple ID

  • Go to appleid.apple.com in a web browser. If you don’t have the packaging or receipt, you can usually find the serial number by signing into your Apple ID on the web. You can do this in any web browser.
  • If you use 2-step authentication to sign in to your Apple ID, you’ll need access to your secondary device to get the login password. If that device is your iPhone that’s not available, you won’t be able to log in.
  • Enter your Apple ID and click the arrow. The password field will expand.
  • Enter your password and click the arrow. This logs you into your Apple ID. If you have two-factor authentication on your account, follow the on-screen instructions to continue the login using your secondary device.
  • Scroll down and click your iPhone. It’s under the “Devices” header. A pop-up window will expand displaying your serial and IMEI numbers.

Pro tip: Always keep a record of your serial number and other important identifiers in case you need support from Apple or wish to check warranty status.

This information is crucial for any device-related issues or support needs. Knowing where to find your iPhone’s serial number can save you time and hassle when reaching out for assistance. It’s beneficial to familiarize yourself with these steps in advance, especially if you’re planning to contact customer support or need to verify your device’s warranty or service eligibility.
