How you find your UDID number on iPhone
What is a UDID used for?
Here’s a refined version of the text:
A UDID (Unique Device Identifier) is a specific reference to an iOS device, used to connect various types of data to that device. It is a fixed value tied directly to the hardware. Depending on how your device functions, the UDID may also be linked to personal information, such as usernames, passwords, and social media logins. While it’s simply a number, when combined with a database, it becomes a key identifier that can connect specific information. Developers often use UDIDs during iOS custom app development to install beta releases for app testing.
Here is how to find your UDID on iPhone
- Open up the latest version of iTunes and connect your iOS device to your computer.
- Select your iOS device by clicking the device’s image located at the upper-left corner of iTunes’s UI.
3. On the next screen, a window should appear listing your phone’s Capacity, Phone Number, and Serial Number.
4. By clicking on Serial Number once, the prompt should change to display your UDID.
Since your UDID will never change (on its own), copy and paste it elsewhere for quick and easy access later in the future!
