Finding your iOS Device’s UDID

Each iOS device has a UDID, or a Unique Device Identifier – a sequence of 40 characters that are unique to each individual device.

Think of a UDID as your phone’s social security number: It’s used by developers to connect particular devices to a specific iOS Developer Account, allowing particular individuals to access and test exclusive content.

Developers typically perform a closed beta before a major release to test the functionality iOS apps on different devices. UDID’s allow devs to assess how their apps perform on particular devices in a way that’s fast, painless and secure. Before starting a beta of your own, you’ll first need to create an Apple Developer’s Account: Click here for a quick how-to!
