Regulation Sets in Pokémon Scarlet and Violet

This is a chronological list of all regulation sets in Pokémon Scarlet and Violet. Regulation sets define the restrictions that exist in a given format of play. The regulation set used for online battles may differ from the one currently active in the VGC Circuit.

Initially, regulation sets used the same Ranked Battles Series (#) format carried over from Pokémon Sword and Shield, however this was standardized to "Regulation Set" on March 1, 2023.

There were no competitive tournaments in the fall of 2022. The first regulation set was introduced on December 2, 2022, coinciding with the start of Ranked Battles Season 1. The games were used in competitive play from Janary 2, 2023 until May 31, 2026. However following the launch of Pokémon Champions on April 8, 2026, a transitional period was introduced where some competitive play occured on Pokémon Champions.
