How to Find UDID of iPhone

A UDID is an acronym used for Unique Device ID (UDID). It is a feature of Apple iPhones and their devices (iPad, iPod Touch, etc.). Every Apple device has its own UDID.

Whenever you go for testing your newly developed testing application on your phone or iPad, you need to provide UDID to the development team.

So now when you know what UDID is, let me tell you how you can find it.

UDID is used by professional computer specialists or computer experts. For example, if anyone wants to test an unpublish application on an iPhone or any other Apple device, then they need to add the UDID in the Apple Developer Certificate. This way, Apple provides security and so we can test a new app only on specific devices whose UDID is added.

We have multiple ways for obtaining the UDID for your iPhone or iPod devices.

Method – 1:

If you want to obtain a UDID without using a MacBook or iMac, then I’ve got you a very interesting way to get the required UDID without using any other device.
