If you want to download beta versions of the iOS you need to have your UDID number to hand and the easiest way to find it is by plugging your device into iTunes and clicking on the serial number of your device, revealing the UDID number. But, what if you don’t have iTunes? How do you find your UDID number then?
How to Find UDID without iTunes :
Using Mac OS X :
There are a couple of methods you can use:
- Connect your device to a Mac
- Click the Apple Menu and choose About this Mac
- Click More Info and System Report
- This opens System Information; click on USB in the left sidebar
- Your device name should appear under which you will see your Serial number – this is your 40-character UDID number
- If you have this installed you will be able to see your UDID number
- Plug your device into your Mac and launch whichever one you have installed – your UDID number will appear on the screen under Serial number
- If you don’t have it , you can download it here – Apple Configurator here.
If you Used iTunes in the Past for Backups
Provided you backed up your data to your Mac then the UDID will be in the file system.
- Open Finder
- Navigate to /User/Library/Application Support/MobileSync/Backup
- There will be a folder for each backed up device and the name of the folder is your UDID number
Any of these methods should work:
- Connect your device to a Windows PC
- IMPORTANT NOTE – Do not make any changes to your registry entries .
- Click Start and type in Regedit
- Click on this result – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
- All your USB devices are listed so look for one that relates to your device and click on it once – a subfolder will appear that has a 40-character string
- Copy the number by right-clicking and selecting Copy Key Name
- Paste it into a text editor and the last 40 characters are the UDID number
If You Used iTunes for a Previous Backup :
As with the Mac, your UDID will be in the file system:
- Click on Start
- Type in this: Users/User/AppData/Roaming/AppleComputer/MobileSync/Backup
- A folder will appear for each device and the folder name is your UDID number
