Regional stage There are four regional divisions (West, Center, North, and East) in the Third League, each containing approximately 10 teams (though the exact number in each division varies by season), which must play home and away games against their regional opponents. From each region, two teams advance to the promotion round, whereas the other teams do not continue the season. This stage of the league is typically contested from April to September. As this is the lowest level of Latvian football, no relegation takes place within the league.
Promotion stage The promotion round involves additional matches between the top four teams of each regional group (A and B), allowing six of the best teams to be promoted to the
Second League at the conclusion of the season. This takes place in a
knockout format, starting from the quarterfinals. The teams contest additional matches in order to determine the exact placement of each team and the league winners. Until the 2025 season, the promotion round involved matches between the top two teams of each regional division, allowing four of the best teams to be promoted, but the rules were changed since the expansion of the Second League to 20 teams starting from the 2026 season. Since 2026, the six best teams from the Third League are promoted to the Second League. ==Past Third League winners==
