Finding your iDevice's Unique Identifier (UDID)

What is the UDID?

Every iPhone, iPad, and iPod (and now Apple Watch) has a Unique Device Identifier, or UDID for short. A UDID 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 your UDID?

Your iPhone can only install betas if it is approved by Apple. By regiersting your UDID with Apple, your device is able to receive these betas and install them without any errors.
