Tangentially, on Android every app you have run at least once can know your phone number through standard APIs. On iOS, as far as I know and as far as I have observed, there is no API for that — apps have to ask the user what the devices' phone number is and trust that input. So Apple revealing phone numbers (through a rainbow table of hashes attack) in this AirDrop sharing scenario isn't congruent with its approach of not revealing phone numbers in other cases.

As far as I'm aware an app either needs explicit permissions (READ_PHONE_STATE) or the user gets prompted when the app requests the phone number (as shown in https://android-developers.googleblog.com/2017/10/effective-phone-number-verification.html https://android-developers.googleblog.com/2017/10/effective-...).
