How to find your Apple device’s UDID

, ,

A UDID is an acronym used for Unique Device ID. It is a feature of Apple iPhones and their other devices. Each individual Apple device has their own ID that is being fetched by Apple servers. When testing a new mobile application on an Apple device we need a UDID from the iPhone, iPad or iPod.

Finding your UDID is a simple process, all you will need is an internet connection, and a few minutes.

UDID
  1. First, go to https://udid.tech on your device, then select the “Tap to find UDID” button located at the top of the screen.
  2. You will then be prompted to accept a configuration file. This file allows the site to read the device information from your phone, so you’ll want to allow this.
  3. Next go to the Settings application, and at the top a “Profile Downloaded” option should now have appeared.
  4. Go into the “Profile Downloaded” menu, and in the top right, press install and accept the prompt which appears.
  5. Once this is complete, you can then go back to https://get.udid.io/ and your UUID will appear. You then have the option to view all the information gathered, or the option to email it.
