What’s the difference between UDID and UUID?

As stated earlier, UDID is the unique 40 hexadecimal identifier code of your Apple 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’ll stay on your iPhone until you delete the app. If any user deletes the app from their 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 for as long as it’s installed.

This is how you can find the UDID of your iPhone and iPad. In 2013, UDID 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.
