The 3. divisjon was known as the 4. divisjon from 1963 until 1990, when the top-tier league changed its name to Tippeligaen, the 2. divisjon became the 1. divisjon and the names of all the lower divisions were adjusted accordingly. Until 2010, there were 24 parallel sections of the 3. divisjon, each consisting of between 10 and 16 teams. The winners paired up and played each other in one home match and one away match in a playoff. Thus, 12 teams were promoted to the 2. divisjon. This system was in place from 2001. The number of teams that were relegated from each section to the 4. divisjon, varied from two to four, depending on the number of teams in each section.

The teams are placed in the 12 sections according to geographic considerations.
