How to Find Your iPhone UUID
If you are beta testing an application, or working with a developer to track down an issue, the developer will almost certainly have to ask you to provide your UUID. This page describes details of what a UUID actually is, and how to find it.
When manufactured every iPhone is assigned an identifier that is unique to that physical device. This is commonly referred to as it’s ‘UUID’, an acronym for Universally Unique Identifier. It’s worth noting that the UUID is anonymous, e.g. if you have a UUID there is no way to tie that to a person.
iTunes will only install applications that have been digitally signed by a developer using an Apple-provided certificate. Applications can either be signed for the AppStore where they can be used by anyone who purchases a copy, or for AdHoc distribution where users install the application by adding it to iTunes. With Adhoc distribution the developer must include the UUID of all devices in the certificate for the application. This is intended to prevent people freely distributing their applications.
Below are instructions for retrieving your UUID. Alternatively you can download Erica Sudan’s most helpful and free AdHoc Helper Application from the AppStore.
1) Start iTunes and connect your iPhone
2) On the Summary page for your iPhone, click on the word “Serial Number:” text
3) The serial number should change to the word “Identifier”, followed by a long string of numbers and digits
4) When you press CTRL+C (Windows) or Command/AppleKey + C (Mac) and the UUID will be copied to the clipboard and can then be pasted into an Email / IM window / whatever

Not helpful. I recently purchase an app for my iPad and it asked for my UUID. It then directed me to this site to help me find my UUID. These instructions are for an iPhone! Not your fault but this is the frustration that turns off many users…..and purchasers!
Perhaps these apps a not ready for “prime time”!
Larry,
You may have already figured this out, however if not, the instructions for the iPhone are the very same for the iPad. Clicking on the “Serial Number” when the iPad is plugged into iTunes, will give you your UDID (guess its no longer UUID).. then clicking on UDID will give your cellular data phone number (Which I thought funny to have a phone number for a device that can’t make calls), then again for the IMEI, then lastly for the ICCID (Should you ever need these identifiers). Now what I don’t understand is, why can’t it be listed in the “About” section of the General Settings ON the iPad?!? The two times I’ve been asked for my UUID, i mean IDID..no wait! UDIDIT…ugh.. you know what I DID, I mean, “mean”… I had no way of plugging in to my desktop and obtaining it…
So a little tip… put this info in your notes section on your iPad so if you’re ever in a situation where you can’t access it from iTunes..
