Now that you’ve got the ID copy it and use it wherever you want.

What is the Difference Between UDID and UUID?

As stated earlier, UDID is a unique 40 hexadecimal character of your device. On the other hand, UUID stands for Universally Unique Identifier, which is on a per-app basis. It recognizes an app installed on your device, and it will stay there until you delete the app. If any user deletes the app from his iOS device and downloads the app again, the ID will be different.

So, in short, UDID is the unique identity of your device, and UUID is the unique identity of an app as long as it is installed.

That’s all, folks!

This is how you can find UDID of your iPhone and iPad. In 2013, UDID had captured a lot of media attention as third-party app developers were sharing this ID with advertising agencies and marketing companies. Apple showed its displeasure and sent an ultimatum to all third-party app developers that if they share UDID of iPhones, Mac, or Apple Watch, their apps won’t find a place in the App Store.
