The 36 teams of the Swiss Football League (Nationalliga) were divided into two tiers.
Each team in each group played a double round-robin in the qualification phase.
The teams took half of the points (rounded up to complete units) gained in the qualification as bonus with them.
The qualification of the NLB began on 28 July 1993 and was completed on 21 November.
Note: because SC Zug had their license revoked FC Emmenbrücke remained in NLB 1992–93
