39C3 Presale: Modus Operandi

We’re happy to finally announce the presale for this year’s Chaos Communication Congress. It will work pretty much the same as last year:

We’ll again be using our system of replicating vouchers. The presale will run in two phases: the voucher phase and the open sale.
We’ll explain this as briefly as we can here. If you want to read more about it, we also have a documentation page available, where we’ll add more information in the coming days.

The voucher phase will run from 2025-10-21 until 2025-11-12 and works as follows:

• There is a fixed quota for this phase. Once this quota is reached, no more tickets will be sold until the open sale.
• All Chaos community groups that have received vouchers from us in the past and answer our inquiry email (see below) will again receive a set of vouchers this year. Each voucher allows the purchase of one ticket. Once this ticket is paid for, a new voucher will be generated (roughly once per day, and only on days when the banks are processing payments). This chain of vouchers will continue until either the quota is reached or the voucher phase ends. These vouchers are intended to be shared within the group and its extended community. It is up to the respective groups how exactly they handle this.
• At the same time, all 38C3 angels who have worked at least 15 hours will receive one voucher. This voucher guarantees the purchase of one ticket until 2025-11-12, even if the quota is reached before then. If you redeem your angel voucher and pay for your ticket while there are still tickets available in the voucher phase, you will receive one additional voucher you can share with a friend. This additional voucher does not generate further vouchers.

Following the voucher phase, there will be two open sale dates, where tickets will be sold at tickets.events.ccc.de. The open sale can be A LOT for newcomers, so you might want to read the guide that we’ll publish in the coming days.
For each date, there is a fixed quota. That means that if the first date sells out, there will still be tickets available on the second date. The dates are:

• 2025-11-08, Saturday, 11:00 Uhr (CET)
• 2025-11-17, Monday, 20:00 Uhr (CET)

We’ve been thinking for many years about how to structure congress admission pricing. Most importantly, we want the broadest possible segments of the community and society to have access to the event. At the same time, we want to keep resisting purely capitalist number-go-up logic. Nevertheless, we need to cover the actual costs of running a large event. We can compensate for this to some degree with the help of the impressive lived solidarity from our community: Roughly a third of you consistently chip in the extra euros for Supporter Tickets on top of standard ticket prices.

The Supporter Tickets—and the huge amount of volunteer work involved in Congress, especially from our angels—continue to enable us to accommodate those for whom money for a Congress ticket is harder to come by. This year, as always, a team of angels will handle requests from all those who request access to a Friends Ticket.

We used every lever available to us over the past two years to avoid making congress more expensive for you on top of all the other price increases in your lives. However, we can no longer escape general inflation this year. As you know, we run the Congresses close to the edge of economic viability—but we still need reserves for future Congresses and Camps, and must offset increased prices for venue rental, technology, materials, and staff. Therefore, we have to raise ticket prices this year, which you can view in the ticket shop.

The most important changes:

• Standard ticket: € 175 € 190
• Supporter-Tickets:
  • € 200 € 220
  • € 235 € 255
  • € 270 € 300

All Chaos community groups will receive an email today to their last known contact address. If you did not receive this email, please contact us at 39c3-tickets@cccv.de by 2025-10-20. In case we have missed an entire group that, in your opinion, should be represented at Congress and is not connected with any other local groups, please also reach out to us at 39c3-tickets@cccv.de. (Please note that groups that are close to each other, either by location or organisation, are expected to share their vouchers – if we started handling more than one group per city/area, we’d have a full-time job on our hands.) Chaos community groups will receive their vouchers on October 21.

All angels who according to Engelsystem have worked more than 15 hours and have given us permission to contact them via email will receive their voucher today. You’re sure you passed the 15-hour threshold, but did not receive a voucher? Please contact us at 39c3-tickets@cccv.de and make sure to include the login name and email address you used at 38C3.

See you soon!
Your 39C3 presale team
