Pokémon Champions Global Challenge I registration opened September 17 at 7:00 p.m. PDT and stays available until September 27 at 6:59 p.m. PDT. Pokémon explicitly allows players to register after the competition has already started, provided the registration window is still open.
That late-entry rule is useful, but registration is not just a button press. A Battle Team must be registered during sign-up, so players should confirm the event rules and team legality before locking in their competition entry.
Pokémon Champions Global Challenge I registration: registration dates
Pokémon Champions Global Challenge I registration runs for ten days and overlaps the live battle period. The competition itself begins September 24 at 7:00 p.m. PDT, which means the final days of registration are also active competition days.

The event closes September 27 at 6:59 p.m. PDT. Players in other regions should convert that time carefully instead of assuming the date changes at local midnight.
Can you register after the event starts?
Pokémon Champions Global Challenge I registration does permit late sign-up. The official announcement directly says you may join the tournament even after it has already begun.
Late registration does not extend the event. A player joining near the deadline still has to register a legal team and complete any desired matches before the same competition closing time.
Registering a Battle Team
Pokémon Champions Global Challenge I registration requires a Battle Team to be selected during sign-up. The competition uses Regulation Set M-C and Double Battles, so the team has to satisfy those event rules.
Because the detailed eligibility list is maintained in the in-game news, checking that list immediately before registration is safer than relying on an older team sheet or a general Ranked Battle assumption.
Where to register in the game
Pokémon Champions Global Challenge I registration is accessed from Battle, then Online Competitions, then the Global Challenge I entry. That is the route described by Pokémon for this event.
Once the event is selected, follow the registration flow and attach the intended Battle Team. Competitive players pursuing Championship Points should also confirm their Trainer Central and Play! Pokémon Access setup before finalising registration.
Account setup for Championship Points
Pokémon Champions Global Challenge I registration does not require account linking merely to compete, but Championship Point eligibility does. Pokémon says the Trainer Central account must exist before registration.
The linked Play! Pokémon Access account must remain connected until rewards have been awarded, and the Pokémon Champions Support ID must be entered there. Players who only want to participate can skip that CP-specific setup.
What to do after registration
Pokémon Champions Global Challenge I registration should be followed by enough event matches to meet your own goal. Three completed wins or losses are required for the Archaludon participation reward.
After the competition, return to Online Competitions and check the ranking result. That ranking check comes before the mailbox claim for Archaludon.
What to prepare before pressing Register
Registration is the point where preparation becomes an event entry. Have the intended Double Battle roster ready first, then compare it with the live Regulation M-C information inside the game. That reduces the chance of selecting a test team, an illegal option or a roster that was built for a different format.
Players joining after September 24 are not breaking the rules: Pokémon explicitly keeps sign-ups open during the competition. The trade-off is simply less playing time. Someone entering on the final day should prioritise a legal team and completed results instead of spending the remaining window repeatedly rebuilding a roster.
Competitive-season players should finish Trainer Central and Play! Pokémon Access setup before this step, because the official Championship Point instructions attach that timing to registration. Casual participants do not need those external links merely to sign up.
The overlap between registration and competition also makes this event different from a traditional sign-up period that shuts before play begins. It gives late players a real route into the tournament, but it is not extra practice time. Once registered, every remaining hour belongs to the same fixed event window, so preparation done before opening Online Competitions has more value than repeated menu changes after entry.

Pokémon Champions Global Challenge I registration is unusually flexible because late entry is allowed, but the deadline is still absolute. Register the correct Battle Team, finish the matches you need and do not leave Championship Point account setup until after registration if points matter to you.
