Pokémon GO code 0004POKEMONGO gives Charmander timed research until September 22

The code is said to unlock timed research with a special Charmander encounter.

According to the same source, the claim period runs until September 22 and the promotion is tied to Pokémon Horizons: The Series, season 3: part 4.

What happened

Game Rant reported on September 18, 2026 that Pokémon GO is sharing a promotional code for a temporary research reward. The code in question is 0004POKEMONGO, and the publication presents it as free to use in-game. The source links the promotion to timed research, but does not list every individual step players need to complete to activate the reward.

According to the report, the reward centers on a special Charmander encounter. In the description, that Charmander is tied to Professor Friede from Pokémon Horizons: The Series. Game Rant also says it is a unique or costume variant of Charmander, but does not provide a full in-game breakdown of all extra rewards, any bonus items, or the exact structure of the research.

The publication names September 22 as the final date to claim the code. That makes the promotion clearly time-limited, according to the source. The report also connects the announcement to the return of Pokémon Horizons: The Series for season 3: part 4, giving the promotion a direct link to an ongoing Pokémon media campaign.

The source provided does not include a full list of regional restrictions, account requirements, or platform differences. As a result, the confirmed details are limited to the code, the time limit, the mentioned Charmander reward, and the tie-in to Pokémon Horizons: The Series. Based on the source alone, it is also not possible to confirm whether the code is still active in every region at the time of publication.

Background

Pokémon GO often uses limited-time promotions to tie content to other Pokémon media. In this case, the code reportedly unlocks a Charmander encounter and directly references Pokémon Horizons: The Series. The combination of a redeem code and timed research fits earlier promotional campaigns in Pokémon GO, but the source provided only describes this specific campaign and not a broader set of similar events.

Professor Friede and Captain Pikachu are mentioned in the context of the promotion, but the source does not specify which extra rewards or research steps are included. The report therefore remains limited to the code 0004POKEMONGO, the Charmander reward, and the stated September 22 deadline. The exact relationship between the promotion and the story of Pokémon Horizons: The Series is also not expanded on beyond the mention of season 3: part 4 as the trigger.

Because the source does not include an official Niantic statement or full in-game instructions, it remains unclear how the claim is entered and whether any additional conditions apply. The available information does mention the code, the deadline, and the thematic tie-in with Pokémon Horizons, but not the full contents of the timed research or any regional or account-type differences.
