Two years ago, Pacific leaders agreed to create a regional free-trade zone by 2020.

Fire protection services are divided into regional zones each with its own independent institution.

Information is provided on the basis of regional zones.

This is the regional zone that will (usually) be where the officer will spend the first 4-8 (or more) years of the career.

Some country calling codes are issued for special services, or for international/inter regional zones.

Each of the three regional zones is divided into four groups.

There are 20 elected board members organized according to the following regional zones:

The First Division consisted of six teams divided into two regional zones.

Nine teams competed in the second division, in three regional zones.

The competition begins as a knock-out competition until the top school in each of six regional zones is determined.
