• Dialing a code:
  Open the Phone app and dial *#06#. The IMEI number will appear on the screen

• On the SIM tray:
  For many iPhone models (such as iPhone 6s and later), the IMEI is printed on the SIM card tray

• On the device packaging:
  The original box your iPhone came in has the IMEI printed on the back

• Using a computer (Finder or iTunes):
  Connect your iPhone to a Mac and open Finder, select your device, and click on the phone number or model info to reveal the IMEI. On a PC or Mac with iTunes, connect the iPhone, click the iPhone icon, then Summary, and click the phone number to see the IMEI

• If you don’t have the iPhone:
  Log in to your Apple ID account page on any device or browser. Under Devices, select your iPhone to view its IMEI number
