Every mobile phone in the world has at least one thing in common: an International Mobile Equipment Identity (IMEI) number, unique to the unit, that can be used to identify it. If your phone is ever lost or stolen, your carrier can blacklist the device via its IMEI number, making it unusable for someone else even if they change the SIM card.
Mobile phone 15 digit IMEI numbers are used to check items such as country of origin, manufacturer and model number. You can also use IMEI to check a device's history and find out if it was ever stolen through services like CheckMend. An obvious but repeatable item: don't share your IMEI number or you risk falling prey to clones and other IMEI-based scams.
Finding your IMEI number is easy, so let's get started.
Check IMEI on an Android phone
On an Android phone, you can find the IMEI in the menu Settings . It can usually be found in one of the following locations:
- Settings> About Phone> Status
- Settings> General> About Device> Status
- Settings> System> About Phone> Status
- Settings> About Device > Status
From there, write down the number or take a screenshot.
Check IMEI on an iPhone
You can find these songs in various places, including Settings, on the physical device, in Finder or iTunes, and on the original packaging.
- Settings> General> About
Scroll down to find the IMEI item in the list. You can also touch and hold the song to copy it to the clipboard and paste it elsewhere, such as in Notes or text.
Find your iPhone's IMEI number from your Apple account
- Go to appleid.apple.com in Safari on Mac.
- Sign in with your Apple ID.
- Scroll to the Devices section until you see the serial and IMEI / MEID number, select the device.
- If you have another device with iOS 10.3 or higher logged into your account (such as an iPad) go to Settings> Your name .
- Scroll to see all devices signed in with your Apple ID and tap the device name to view the serial and IMEI / MEID number.
You can also find the serial number for your device in the Finder or iTunes.
- Connect your device to your computer.  Start the Finder on a Mac with MacOS Catalina 10.15 or higher. Open iTunes on a Mac running MacOS Mojave 10.14 or earlier or on a PC. Now find your device.
- Click on the tab Overview to see the information.
- Click phone number under your device name or device model to get the IMEI / MEID and ICCID numbers.
You can also find it in the Preferences> Apple ID> iPhone.
Other ways to check your IMEI
Some devices display the IMEI number on the SIM tray. Apple says you can see the IMEI numbers on the SIM tray in every generation of iPhone from the 6s through iPhone 11, except for the SE. Some phones, like the Samsung Galaxy S10 and other Samsung Galaxy phones, show the IMEI number on the back of the case, embedded in a small, almost translucent type – you need a magnifying glass to read it and even then it will are hard to see. Older phones with removable batteries can also list the IMEI under the battery or on top of the SIM slot.
Check IMEI on the box
If your iPhone or Android phone has been stolen and you forgot to check and write down the IMEI number, it is still possible to localize. If you've kept the box your phone came in, there's a good chance you'll find a sticker somewhere on the outside with your phone's IMEI number.
Check IMEI with a telephone dialer
To get your IMEI number, dial * # 06 #  A box should appear with your IMEI number in it and you can copy the number or take a screenshot of it before rejecting it.
This technique seems largely obsolete, although it sometimes works. In the past, this universal method of checking your IMEI worked on most mobile phones, both iPhone and Android, and it is a popular method that often comes up in a search. The problem is that it no longer works properly. Of three of the four phones tested, only one (a Samsung Galaxy S6 Edge Plus 2016) gave the expected result. Neither the iPhones or LG V40 ThinQ we tested came up with the number after dialing the code. Apple's instructions don't include this method either. So we mention it here as a historical artifact and last resort.
