The Unique Device Identifier (UDID) is a 40-character alphanumeric that works as a device-identifying mechanism. If you are an app developer and you wish to test the app, you will be asked for UDID. Here we’ve explained three methods to find UDID of iPhone and iPad. Let’s check it out!
- How to Find UDID of iPhone or iPad without Mac
- How to Find UDID of iPhone without iTunes
- Get the UDID Using Xcode
- What is the Difference Between UDID and UUID?
How to Find UDID of iPhone or iPad without Mac
This method works on iPhone SE 2020, iPhone 11 Pro Max, iPhone X series, iPhone 8, and earlier devices.
- Open Safari on your iOS device and head over to ShowMyUDID.
- Now, hit Tap to Show UDID.
- Next, a popup will appear, saying, ‘The website is trying to download a configuration profile. Do you want to allow this?’ Tap on Allow.
- Next up, another popup will appear confirming that the profile has been downloaded and suggest installing it from the Settings app. Tap on Close.
- Up next, open the Settings app on your device and then tap on the Profile Downloaded option.
- Now, tap on Install at the top right. You will need to authenticate using the passcode. Then, tap on Install again.
- You will be directed to the site where you will see the UDID of your iOS device. (It will also show other information like IMEI, serial number, etc.) Now, you can copy UDID and save it at the desired location or send it via email.
Finally, now that you’ve found the UDID of your iOS device delete the profile. Just go back to the Settings app → Tap on Profile Downloaded → Tap on Remove Downloaded Profile.
How to Find UDID of iPhone without iTunes
In 2018, Apple removed the ability to check UDID in iTunes.
- First off, connect your unlocked or locked iPhone to your Mac.
- Now, click on the Apple logo at the top right and select About This Mac.
- Next, click on System Report.
- From the Hardware section, click on USB.
- Next up, click on iPhone.
- Check out the Serial Number label. You need to copy the number that is next to it and paste it in a note. Now, you have to add a – (hyphen) after the 8th digit.
Let’s say, the serial number looks like: 000011114567899. When you include the hyphen, it will be: 00001111-4567899. It’s your iPhone’s UDID.
Get the UDID Using Xcode
Here is how to get UDID of any iPhone and iPad using Xcode. Xcode is a tool by Apple for developing apps for iOS, watchOS, macOS, and tvOS.
- First off, download Xcode, if you haven’t already. It is free.
Note: The installation of Xcode takes considerable time. So, finish your other work while it installs.
- Now, you need to connect your iPhone to the Mac using a USB cable.
- Next, open the Xcode app → Click on Window and select Devices and Simulators.
Alternately, you can just enter Command + Shift + 2 key
- Next up, ensure that the Devices tab is selected. Then, check out the Identifier that’s the UDID of your iPhone.
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.
