Liga IV

Liga IV is the fourth level of the Romanian football league system. Its name was changed from Divizia D into Liga IV before the start of play for the 2006–07 season.
Current format.
Liga IV has 42 divisions. The divisions are regionalised and are organised by every county association. Each team plays in their own county. The county associations decide how many teams play in the league and how many matches each side plays. In Romania the most frequently used system is one division with matches played home and away. A number of associations prefer 2 or even 4 parallel divisions with the teams finishing first meeting in a play-off to decide the champion. The number of teams differ from one county association to another. The Mureş County association has the fewest teams, 8, which play in a Scottish system, playing 4 times against one another. The Dolj County association has 20 teams.
Promotion.
The champions of each county association play one another in a play-off to promote to the Liga III. Geographical criteria are taken into consideration when the play-offs are drawn. In total there are 41 county champions plus the Bucharest municipal champion.
Series.
Liga IV is divided in 42 series, one for each county. All county leagues are organized individually by every County Football Association (AJF), but under the supervision of the Romanian Football Federation.
Other teams (2020–21).
Some teams decided to not participate in the 2020–21 Liga IV season due to COVID-19 pandemic situation. Their status is unclear at this moment.
