History

The congress is held in Germany. It started in 1984 in Hamburg, moved to Berlin in 1998, and back to Hamburg in 2012, having exceeded the capacity of the Berlin venue with more than attendees. Since then, it attracts an increasing number of people: around attendees in 2012, over in 2015, and more than in 2017. Since 2017 it has taken place at the Trade Fair Grounds in Leipzig, since the Hamburg venue was closed for renovation in 2017 and the existing space was not enough for the growing congress. A large range of speakers are featured. The event is organized by volunteers called ''Chaos Angels''. The non-members entry fee for four days was

An important part of the congress are the ''assemblies'', semi-open spaces with clusters of tables and internet connections for groups and individuals to collaborate and socialize in projects, workshops and hands-on talks. These assembly spaces, introduced at the 2012 meeting, combine the ''hack center'' project space and distributed group spaces of former years. From 1997 to 2004 the congress also hosted the annual German

Championships. 2005 was the first year the Congress lasted four days instead of three and lacked the German Lockpicking Championships. 2020 was the first year where the Congress did not take place at a physical location due to the COVID-19 pandemic, giving way to the first Remote Chaos Experience (rC3). The Chaos Computer Club announced to return to the now newly renovated Congress Center Hamburg for the 37th edition of the Chaos Communication Congress. The announcement confirms the usual date of 27-30 December, notably omitting the ''year'' it will be held. On 18 October 2022, they confirmed that the congress will indeed not be held in 2022.
