Geographically, the league covers Aberdeen City, Aberdeenshire and Moray.

The winners take part in an end of season promotion play-off with the Midlands Football League and North Caledonian Football League champions, subject to clubs meeting the required licensing criteria.

The 2018 league was essentially a continuation of a two division system which operated from 2003.

After five seasons of that setup, a three-division model was restored.

In the semi-finals, the Premier League side plays the fifth-placed Championship side, and the fourth and fifth-placed teams play each other, both games over two legs.
