Unique Device Identifier (UDID) is a set of 40 alphanumerics that are designated to each iPhone, iPad and iPod Touch to distinguish it from the others. UDIDs are used by developers to register devices with Apple’s dev programme that they’ll be using during their app’s testing in developmental as well as beta mode.
If you’re an inquisitive one and can’t wait to try out all the upcoming features of your favourite apps or games before the majority of the users do, you’ll need your iOS device’s UDID sequence to get into beta programmes as developers need to submit it to Apple for approval.
While there are a number of third=party apps and websites that enable users to find the UDID number in a jiffy, since you can find the UDID of your iPhone via iTunes on your PC, it doesn’t make much sense to give a non-trusted third-party app access to your phone’s details.
Below we’ve explained how you can find your iPhone’s UDID via iTunes on your Mac or Windows PC in three simple steps.

Find UDID of your iPhone via iTunes
Connect your iPhone, iPad or iPod Touch to your PC, launch iTunes and follow the steps below to find the UDID of your device.
Step 1: Click on the phone icon near the top-left corner of iTunes (below Account on the toolbar at the top).
Step 2: On the next Summary page, click on Serial Number.
Step 3: Clicking on the Serial Number will change it to UDID, which will then display the 40-character-long UDID of your iPhone.
In addition to UDID, if you keep clicking on the same spot where serial number and now UDID are displayed, you will also find your device’s ECID and Model Identifier.
Similarly, if you click on Phone Number above the Serial Number, you’ll also be able to see your iPhone’s MEID, IMEI and ICCID.
