Locating the serial number on an iPhone is a straightforward process that provides access to critical details about your device. This unique identifier is essential for checking warranty status, verifying authenticity, or seeking technical support from Apple or your carrier. You can find this code in multiple locations, depending on whether you have physical access to the device or need to retrieve it from outside the system.
Locating the Serial Number on the Device Back
The most traditional method involves a direct view of the hardware engraving. For iPhone models without a physical SIM tray, such as the iPhone XS, iPhone 12, and later, this number is etched onto the rear glass panel. You can find it positioned next to the bottom edge, close to where the text "Designed by Apple in California" is printed.
Steps for Back Engraving
Place the iPhone face down on a clean, flat surface.
Ensure the device is powered off to avoid any smudges on the screen.
Look for a small line of text that begins with the letters "F" or "M" followed by a series of numbers and letters.
Reading the Serial Number via Settings
For devices with a cracked screen or those that are powered on, navigating the software interface is the safest option. This method bypasses the need to handle the device physically and provides immediate access to the serial number alongside other identifiers like the IMEI.
Navigation Path
Open the Settings app on your home screen.
Tap General , then select About .
Scroll down the list of details until you see the row labeled Serial Number .
Using the SIM Card Tray
On older iPhone models that feature a removable SIM tray, the serial number is printed directly on the tray itself. This method requires ejecting the tray using the provided SIM ejector tool or a paperclip. This physical label is helpful if the screen is unresponsive or if you need a backup reading.
Retrieving the Tray Label
Insert the ejector tool into the small hole beside the SIM tray.
Pull the tray out gently and locate the printed sticker on the tray frame.
The serial number will be listed under "Serial" or "S/N" on that sticker.
Checking via iTunes or Finder
If the iPhone is disabled or the screen is not responding, connecting the device to a computer remains a reliable way to retrieve identification data. Both iTunes on Windows and macOS, and the Finder on macOS Catalina and later, display the serial number once the device is recognized.
Connection Steps
Connect the iPhone to your computer using the original USB cable.
Open iTunes or Finder and select the device icon when it appears.
Click on the Summary tab to view the serial number alongside the device name and version.
Finding the Number Through iCloud
Users who utilize Apple's ecosystem can locate the serial number remotely through iCloud.com. This method is particularly useful if the device is lost or stolen, as it allows you to verify the device details without having the physical unit in hand.
iCloud Web Interface
Navigate to iCloud.com and sign in with your Apple ID.
Click on the Find iPhone application.
Select the device from the map view; the serial number will be listed in the details panel.
