A unique number (identifier) is assigned to every iPhone when manufactured. This number is commonly referred to as its UDID (Unique Device Identifier).

For the AdHoc distribution where users install the application by adding it to iTunes, the application should be digitally signed by the developer (or the company) and the mobile provisioning profile should contain the users’ iPhone identifiers.

This means that the users (or testers) should provider their iPhone identifier to the developer (or the company) so that the developer (or the company) can build an application package that can be installed and run on each user’s iPhone.

Here is how to get the iPhone/iPod Touch identifier:

1. Launch iTunes application and connect your iPhone to the computer.

2. Click your iPhone under Devices menu in the left panel.

3. Under Summary page for your iPhone, click Serial Number:

4. ‘Serial Number:’ will be changed to ‘Identifier:’ and a long sequence of alphabets and numbers will be displayed

5. The identifier is not highlighted, but you still can copy it. When you press CTRL+C (on Windows) and Command+C (on Mac) , the identifier will be copied to the clipboard. Press CTRL+V (on Windows) and Command+V (on Mac) on any text editor.
