If you are a developer, entrepreneur, or even a user, chances are you may need a string of a long alphanumerical Unique Device Identifier or UDID for iOS development. This number is exclusive to your physical device, your iPhone, iPad, and iPod Touch. Developers, especially, need the UDID to register devices in the process of development.

What is a Unique Device Identifier?
A Unique Device Identifier (UDID) is a unique sequence of alphanumerical (a combination of letters and numbers), particular to your device alone. All iPhones, iPad, or iPod Touch have this UDID. It is a string of a 40 alphanumerical identity (for iPhone X models and ones before that). It may resemble serial numbers you find on the packaging. For iPhone XS and the later models, it comes as a 24 alphanumeric string with a dash after the 8th digit.

6 Steps to Find UDID on iPhone
In order to register a device for testing, you need to first find its UDID.

Step One: Initiate iTunes and connect your device

Step Two: Go to Devices and select your device by clicking on it.

Step Three: Click on ‘serial number

Step Four: Your ‘serial number’ will automatically change to your UDID

Step Five: Click on the ‘Edit’ icon, then ‘Copy’

Step Six: ‘Paste’ the same (taken from iTunes menu) into your email. The email message will display your UDID.
