Format
Liga II has two parallel regional divisions, Seria I and Seria II, each with 16 teams. The clubs are divided based on a geographical criteria in order to avoid lengthy and expensive travels.
Generally, Seria I contains eastern teams while Seria II contains western sides, although clubs near the center of the country are allowed to choose in which series they will compete.
The first two teams in each series promote to the Liga I, while the last three in each series relegate to the Liga III.
