The Dutch Tweede Divisie in the 1962–63 season was contested by 34 teams. Due to a large number of teams entering from the higher Eerste Divisie after mass relegations there, there were 22 new entrants.
Teams were divided in two groups of seventeen teams. The champions played a play-off for promotion. After that match, a mini-tournament was held to determine a second team that would be promoted. It turned out that group B runners-up BVV would be promoted and not group B champions Haarlem.
New entrants
There were only twelve teams that had been participating in this league last season, meaning there were 22 new entrants. Many of the new entrants were teams that were promoted in the previous seasons of the Tweede Divisie. Due to the reorganisation in professional football by the KNVB, many teams were back to where they started.
Several play-offs were held to determine the league champions, who would be promoted to the Eerste Divisie, and who would leave the Professional leagues altogether.
However, as no amateur team wanted to enter professional football and VV Oldenzaal decided to return to amateur football on a voluntary basis, PEC weren't relegated.
