A Raid Pass (Japanese: レイドパス Raid Pass) is an item in Pokémon GO that is required to join a Raid Battle. Once a player uses a Raid Pass, they will join a lobby with all the other raid participants. Raid Passes cannot be refunded even if the player decides to quit before or during a raid. Using a single Raid Pass, a player may attempt a raid as many times as they like until they win the raid or the raid expires.
There are three types of Raid Passes: free Raid Passes, Premium Raid Passes, and EX Raid Passes. Free and Premium Raid Passes are effectively identical, but obtained in different ways. When joining a raid, the game will prioritize using a free Raid Pass before tapping into the premium ones. EX Raid Passes can only be used to join EX Raids, which have a set time and location in advance.
A free Raid Pass may be obtained only once a day by spinning the Photo Disc of a Gym if there is not one in their Bag. If the player already has a free Raid Pass from a previous day, they must use it first before obtaining another one.
EX Raid Passes are distributed on a semi-random basis to players who have recently completed a Raid at the same Gym the EX Raid is to take place. Each EX Raid Pass allows a player to invite one Ultra Friend to participate, but may not send another even if the invitation is declined.
