This guide will help you retrieve your Unique Device Identifier (UDID). An UDID is necessary for registering your iDevices with Apple's Beta testing program. This identifier allows you to activate the beta builds of the latest iOS on your iDevices, making it a fully functional iOS for testing/development purposes.
What is a UDID?
UDID (Unique Device Identifier) is your iDevice's unique identifier that an iOS dev needs to register with Apple. Each iPhone or iPod Touch has a UDID, which is a sequence of 40 letters and numbers that is specific to your device. It’s like a serial number but much harder to guess.
Why do we need a UDID?
Your iPhone can only install programs that are approved by Apple. Applications in the App Store have been approved by Apple for general distribution, but beta customers get to try the app before it’s in the store. We register your UDID with Apple so they can approve our application especially for your iPhone. Once registered, Apple keeps a track of the devices activated on an iOS dev's account on Apple's Beta testing list.
How do I get the UDID for my device?
- Launch iTunes and connect your iPhone/iPod Touch/iPad.
- In the right pane, locate the information about your iPhone, including its name, capacity, software version, serial number, and phone number.
- On the Summary page for your iPhone/iPod, click on the word Serial Number text. Note that the serial number is not the same as the UDID. After you click on the words Serial Number, it should change to the word Identifier, followed by a long string of numbers and digits. This long string is your UDID.
- Press CTRL+C (Windows) or Command/AppleKey + C (Mac) and the UDID will be copied to the clipboard and also by choosing Edit ? Copy otherwise.
- You can now save this or even mail this UDID to yourself.
