If you're planning to buy a used Apple Watch, you might want to check its serial number or IMEI number. Using these, you can make sure that everything is on the up and up. Here's how to find the numbers from your Apple Watch and iPhone.

Find Serial Number and IMEI on Your Apple Watch

On your Apple Watch, press the Digital Crown from the watch face to open the apps grid or list.

Press the Digital Crown

Here, find and tap on the "Settings" app and then select the "General" option.

Tap on Settings app and then select General

Tap on the "About" option.

Now, scroll down and look for the "Serial Number" and "IMEI" sections. The IMEI number is only available on Apple Watch Series 3 (GPS + Cellular) and higher.

If you can't boot up your Apple Watch, you can also find the serial number on the case.

To find the serial number on Apple Watch Series 1 and above (including the Nike+ and Hermès models), remove the portion of the band closest to the Digital Crown from your watch. You'll find the serial number in the band slot.

If you're using the first-generation Apple Watch, you'll find the serial number on the back of the case, in the periphery of the black circle.

If you're buying a used Apple Watch, make sure to check the serial number on both the Apple Watch case and from the Settings app. If they don't match, then someone might have replaced the case on the Apple Watch, and you should probably stay away from it.

Find Serial Number and IMEI on Your iPhone

You can also find the Apple Watch serial number and IMEI from the Watch app on the paired iPhone.

After launching the Watch app, tap on the "My Watch" tab. Here, go to the "General" section.

Tap General

Next, tap on the "About" option.

Tap About

From this screen, look for the serial number or the IMEI number.

If you can't find the serial number from the above options (if you've lost your Apple Watch), you'll also find it on the Apple Watch box or on the original receipt.

If you've lost your Apple Watch, you can track it using the Find My app on your iPhone.
