The end zone refers to the scoring area on the field, according to gridiron-based codes of football. It is the area between the end line and goal line bounded by the sidelines. There are two end zones, each being on an opposite side of the field. It is bordered on all sides by a white line indicating its beginning and end points, with orange, square pylons placed at each of the four corners as a visual aid. Canadian rule books use the terms goal area and dead line instead of end zone and end line respectively, but the latter terms are the more common in colloquial Canadian English. Unlike sports like association football and ice hockey which require the puck or ball to pass completely over the goal line to count as a score, both Canadian and American football merely need the nose of the ball to break the vertical plane of the outer edge of the goal line. A similar concept exists in both rugby football codes, where it is known as the in-goal area. The difference between rugby and gridiron-based codes is that in rugby, the ball must be touched to the ground in the in-goal area to count as a try (the rugby equivalent of a touchdown), whereas in the gridiron-based games, simply possessing the ball while it is in the end zone is sufficient to count it as a touchdown. Ultimate frisbee also uses an end zone scoring area. Scores in this sport are counted when a pass is received in the end zone.
