Introduction
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.
What is the significance of UDID?
Apple must affirm and sanction all programs installed on your Apple device. All apps you come across on your App Store are there post Apple’s approval. However, during the beta testing stage, the app can be tried before it is officially launched for general consumption. For this very reason, UDID is registered with Apple- to approve the application for your device.
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.
