The format has been maintained to two series, each of them having 14 teams. At the end of the season the winners of the series promoted to Divizia A and the last two places from each series relegated to Divizia C.[1][2]
Constructorul Brăila (at that time Progresul Brăila) was relegated to the Local Championship (equivalent of Liga IV or Divizia D) at the end of the 1962–63 Divizia B season due to match fixing. After relegation, a new entity, Laminorul Brăila was enrolled in the re-established Divizia C, the new entity also merging with the old one thus becoming its successor. In this way it was possible that after a single season of absence the team would re-appear in the Divizia B, this time under the name of Constructorul Brăila.[3]
