Begin by plugging in the device and starting iTunes. Choose your device in the DEVICES section on the left side of iTunes. At this point you should see the iPhone stats (name, capacity, software version, etc) similar to the figure below. By default the serial number will be shown on the second line from the bottom:

If you click the Serial Number, the content of that row will change to show the UDID:

To copy the UDID to the clipboard, from the Edit menu inside iTunes, choose Copy. You can now paste the UDID as needed into an email, document…

Creating More Readable Link

If you want to create a link that is easier to read, you can follow the format shown below, replacing your application name where indicated:

http://itunes.com/apps/application_name_here

For example, the equivalent link to the Cartoons To Go app new becomes: http://itunes.com/apps/cartoonstogo

Notice that I removed all the spaces in the application name. Here is the complete list of naming requirements:

- Remove all whitespace
- Remove the following characters and symbols: !¡”#$%’()*+,\-./:;<=>¿?@[\]^_`{|}~©™®
- Replace ampersands with the word “and”
- Accented characters such as ü should be replaced with base character (for example “u”)
- Use only lower-case letters

The above rules apply to both linking to your application as well as the company name. For example to access the company name 3 Sixty Software, LLC in the App Store, the readable link is: http://itunes.com/apps/3sixtysoftwarellc.

Even though you can’t use iTunes to upload new apps, change current app descriptions, prices, etc, you can access your reports with the following link: https://itts.apple.com
