How to check your iPhone’s UDID from iTunes
iPhone developers can beta test their iPhone applications on up to 100 devices, however this requires that the developer add the test iPhones‘ UDID (Unique Device Identifier) to their application.
To find an iPhone’s UDID, connect it to your computer, open iTunes, select the iPhone from iTunes‘ devices list and click on the Summary tab. iTunes will list your device’s Name, Capacity, Software Version, Serial Number and Phone Number.
Clicking on the Serial Number will change it into the UDID, and pressing ⌘-C (Command-C) on your Mac will copy the UDID to your clipboard.

There is an alternative for the ones that do not use iTunes. Just download an app called “UDID”. It will send you an email informing your identifier.
