Your UDID is a unique number that identifies your iOS device. We’ll need this code during the beta testing phase of development, in order to provide you with apps to test. Fortunately, it is very easy to find your UDID. In order to make it even easier we have provided some instructions on how to find your UDID using the latest version of iTunes, below.
If you are developing an iOS app with Cranworth Medical then we may need your UDID in order to provide you with app versions for testing. Please note this only applies to iOS (iPhone/iPad) apps and not to Android apps.
There are two ways to find your UDID: 1) via itunes and 2) via an App.
Please note: this page contains links to third party products. We cannot verify their functionality or directly support their use. We strongly recommend you use the iTunes method described below.
What is my UDID?
Each iOS device has a unique number – Unique Device IDentifier (UDID) – which is a sequence of 40 letters and numbers specific to that device. It looks like this:
Why do you want my UDID?
Any iOS device (iPhone or iPad) can only install apps approved by Apple. This approval process happens when Apple accept the app for distribution on the Apple App Store. If we need to give you an app for testing purposes (‘beta’ testing) then we have to certify a copy of that app specifically for your device – and this process uses your unique UDID so that only you can install the beta version.
Finding your UDID using iTunes
This method is more involved but doesn’t require you to install a 3rd party app.
1. Open iTunes on your desktop computer.
2. Locate your device information by selecting your device from the drop-down menu.
3. Click on ‘Serial Number’ and it should change to ‘UDID’.
4. Copy the UDID to your clipboard by right clicking on the UDID and selecting ‘copy to clipboard’.
5. Paste the UDID into an email to email@example.com
Finding your UDID using an app
It is possible to get your UDID directly from your iPhone or iPad. This method is simpler, but it does require you to install a third-party app. ‘Ad Hoc Helper’ from Erica Sadun is one solution.
1. Install Ad Hoc Helper from the Apple App Store.
2. The app will create an email with a copy of your device’s UDID. Send this email to firstname.lastname@example.org.
