N.B.: area code is a very ambiguous concept, so the I18N team generally recommends against
using it for most purposes, but recommends using the more general {@code nationalNumber}
instead. Read the following carefully before deciding to use this method:
- geographical area codes change over time, and this method honors those changes; therefore, it doesn't guarantee the stability of the result it produces.
- subscriber numbers may not be diallable from all devices (notably mobile devices, which typically requires the full national_number to be dialled in most regions).
- most non-geographical numbers have no area codes, including numbers from non-geographical entities
- some geographical numbers have no area codes.
