Exempt Catholic Dioceses (directly subject to the Holy See)

These (arch)dioceses are exempt from belonging to any ecclesiastical province, hence only the Vatican can exert the authority and coordinating functions normally falling to the Metropolitan Archbishop. They are grouped here geographically. Nevertheless, most belong to an episcopal conference, in which case the more relevant mention is in its geographical region, as exempt dioceses as such do not have specific ties with each other.

Military ordinariates are in pastoral charge of the troops of a state, but may be vested in a Metropolitan Archbishop, typically in the national capital.

Also generally exempt are the apostolic prefectures and apostolic vicariates, which tend to be temporary missionary dioceses, expected to become part of an ecclesiastical province when promoted to regular (arch- or suffragan) bishopric.
