Finding the UDID of an iOS Device – Here’s How!

What is a UDID?


UDID is nothing but Unique Device Identifier (UDID). Working as a communicator between the Apple server and iOS devices, this is a feature provided by Apple to identify an iOS device.


Why is it required?


All the iOS apps are signed in using a provisional profile that allows the apps to be installed only on iOS devices. Before signing any app, a UDID has to be added to the provisional profile to enable the app to be installed on an iOS device – hence, making it an extremely important component.

With macOS Catalina, Apple has replaced iTunes with three separate apps: Music, TV, and Podcasts. Now, this makes it impossible to fetch the UDID through iTunes. But fret not, here’s how you can find the UDID of iOS devices (iPhone and iPad), without using iTunes!


Finding the UDID without using Mac (Using UDID.io)


Secure for sure!


Disclaimer: UDID.io doesn’t store any of your private data on their servers. All the data transmitting to your browser is encoded using 256-bit AES to prevent it from getting hijacked. At all times, make sure that you don't share your UDID of iPhone and the IMEI or serial number with any non-trusted third-party entity to prevent any potential fraud.

1. Open UDID.io in Safari on your iPhone or iPad.

2. Next, you will see a popup that reads, ‘The website is trying to download a configuration profile. Do you want to allow this?’ Tap on Allow.


3. After that, you will see another popup confirming that the profile has been downloaded and asking you to manually install it from the Settings app. Tap on Close.

4. Now, open the Settings app and tap on More for your iPhoneView Profile.

5. Tap on the Install button that you will see on the top right. You will then need to authenticate using your passcode. Once done, tap on Install again.

6. Once it’s installed, 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.).

Voila! You can copy the UDID from this screen and simply share it via email.

Important: Once you’re done with the process, don’t forget to delete the profile.


For this, go back to the Settings app and then to More for your iPhoneView Profile → Tap on Remove Downloaded Profile.

Finding the UDID using MAC:

1. Connect your device to a Mac device using a USB cable and tap on your device name in the sidebar menu. Next, simply click on the tab under the device name.

2. Now, you will see the UDID of your iOS device (it will also display other information like the serial number, etc.). Right click on this info and copy the UDID.

Finding the UDID using XCode


Apple’s tool for developing apps for iOS, watchOS, macOS, and tvOS – XCode can also be used for this purpose!


1. Connect your device to a Mac device using a USB cable.


2. Next, open the XCode Tap on Window and select Devices and Simulators.

Alternately, you can just press the combination of Command + Shift + 2 keys.


3. Once done, ensure that the Devices tab is selected. Then, check the Identifier, which is the UDID of your device.
