What Is A Unique Device Identifier?

Each iPhone, iPod Touch or iPad has a unique serial number comprised of 40 letters and numbers. This is known as the Unique Device Identifier, and more commonly by its acronym UDID. You can think of this as a hard to guess serial number and is preset into the device, by Apple, at the time of manufacture.

Why do we need to know your UDID?

Each FrontGate account uses a limited number of devices and an account needs a way to recognise your phone or iPod.

How do I get the UDID?

Normally the simplest way to get the UDID is to use iTunes, when the device is connected using the USB cable, to read the value. Sometimes, especially when you are away from your desktop, it may be more convenient to download a small utility from the App Store.

Using iTunes

1. Open iTunes and connect your device using the USB cable.
2. In the source list, on the left, select your device.
3. In the main panel, show the device's information by selecting the tab labelled Summary
4. Reveal the identifier by clicking the label text Serial Number
5. Copy the value to the pasteboard by selectingthe Copy item from the Edit menu.
