If you are a developer who bought an iPhone 11, iPhone 11 Pro or iPhone 11 Pro Max for work, then you will need to find out the serial number (UDID) of your smartphone in order to register it on the developer portal. Fortunately, this can be done without iTunes and even without a computer.
It is important for developers to register their devices on the Apple website for developers, since otherwise it is impossible to officially install beta versions of the system. There are two ways to find out the serial number (UDID) of an iPhone. For one you need a Mac, and the second does not require a computer at all. The first method is official, and the second one was invented by users. None of them require iTunes as before.
