What does Application package identifier mean?
An application package identifier is a software identifier used by a platform to distinguish an app from others. It is different from the friendly display name and icon, both of which can be similar across unrelated products.

The identifier can help support distinguish apps with names such as VIP, VIP+ and Pro, but it should be considered alongside publisher and signing information. An identifier alone does not establish trust, because the distribution and platform context still matter. Record it accurately if the app or operating system exposes it, without posting private account screens.
