What is an IMEI number?
The IMEI (International Mobile Station Equipment Identity) is a 15 digit number that identifies a phone. It’s also used to block your phone if it’s stolen.
Why do I need my IMEI number?
Your IMEI number helps to identify your phone if it's been stolen or lost, and allows it to be blocked from your network provider. You'll also need your IMEI number to check your device is compatible with 4G/5G now we've switched off our 3G network.
How to find your IMEI number
The simplest way to find your phone's IMEI number is to key *#06# into your phone keypad. This will reveal a series of numbers, look for the one labelled IMEI.
You can also find it in your phone Settings, or in the battery compartment if your phone has a removable battery.
Go to Settings > General > About. The IMEI number is listed in a section called PHYSICAL SIM. Make a note of the number or use the copy function on your phone.
Go to Settings > More > About device > Status. The IMEI number is listed along with other information about your phone. Make a note of the number or use the copy function on your phone, if it has this capability.
If you’re using an Apple Watch, open the ‘Watch’ app on the iPhone that’s paired with your Watch. Press ‘My Watch’ at the bottom of the screen, then press ‘General’ and ‘About’. You’ll find the IMEI on this page.
Alternatively, open the Settings app on your Watch and choose ‘General’, then ‘About’. If you have an Android smartwatch, like a Google Pixel Watch or Samsung Galaxy Watch, the steps can vary.
Typically, you’ll find it by swiping down from your watch’s home screen and looking for an ‘About’ option, but you may need to check your device’s user guide for specific instructions.
