A Unique Device Identifier (UDID) is different from an iPhone or iPad's serial number. The UDID is 40 digits with both numbers and letters, and this can be used to uniquely identify your iOS device. Because of this, avoid sharing this number with untrusted parties. Here's how to obtain the identifier number (UDID) for an iPhone, iPad, or iPod.

Things You Should Know

Plug your iPhone or iPad into your Windows PC and open iTunes. Open your device details and click the serial number to show the UDID.
On Mac, plug in your device and open the Finder. Click your device, and click the number under its name to show the UDID.
