What is the UDID?
Each iPhone, iPad and iPod Touch has a Unique Identifier (UDID) which is a sequence of 40 letters and numbers that is specific to your device. It looks something like this: e67e2e19665b8b8a251234b77664b3439ad8e837.
Why do we need the UDID?
Your iPad, iPhone or iPod Touch can only install applications that have been approved by Apple. Applications in the App Store have been approved by Apple for general distribution but we can also distribute applications to specific devices before they are released in the App Store. This is a great tool for previewing your content.
How do I find my UDID?
You can either copy/paste your UDID from iTunes or email it directly from your device by using a free app available on the App Store.
Copy/Paste from iTunes
- Launch iTunes and connect your iPhone, iPad or iPod Touch to your computer using a USB cable.
- Select your phone from the Devices section on the left hand pane.
- In the right pane, ensure the Summary tab is visible showing the device name, capacity, software version, serial number, etc.|
