Tickets

Tickets will be available for online presale (no on-site sales!) at tickets.events.ccc.de. If you have questions or need help, please check the FAQ below. If you can’t find an answer there, contact us via email.

Presale Mode

The presale takes place in two distinct modes: The Community Sale up to 2025-11-12, and the Public Sale with two presale dates. In the first mode, tickets can only be purchased using a voucher (more on this below). In the second mode, tickets will be available for open sale.

If you’d like to know more about the reasons behind this model, head over to our long explanation post from back at 36C3, or in this year’s announcement post.

Public Presale Dates

No tickets will be sold on-site during the event. The tickets will be available for open presale on tickets.events.ccc.de on the following dates:

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

You can find more information on the public presale dates below.

If there are tickets left after the public presale, we will open the webshop again at a later date. In this case, the shop will stay open until all tickets are sold (or until just before Christmas, whichever comes first).

Ticket Prices

  • Standard Ticket: 190 €
  • Supporter Ticket: starting at 220 €
  • Business Ticket: starting at 575 €
  • Up-and-coming Ticket (U18): 50 € (free admission for children under the age of 12)
  • Member Ticket (for members of CCC e.V.): 175 €

As always, we’re also offering Friends Tickets: People who cannot afford the Standard Ticket can request a Friends Ticket at a reduced price. The exact price will be determined individually in a conversation with the Friends Ticket team.

We think it’s important to offer the Friends Ticket and the Up-and-coming Ticket. At the same time, we need to reach an average ticket price of 200 € to meet our budget. That’s why we’d like to ask you to buy the Supporter Ticket, if you can. And if your employer is paying for the ticket, please buy a Business Ticket (only Business Ticket owners will receive their invoice prior to the event). It’s only thanks to Supporter tickets and Business tickets that we can offer Friends tickets and Up-and-coming tickets in the first place.

Community Presale

In the Community Presale, tickets can only be purchased using a voucher. Vouchers are given to:

  • Groups that are part of the Chaos community (registration deadline 2025-10-20). Groups will receive a set of vouchers that will replicate repeatedly (more on how this works below). These vouchers do not guarantee any tickets – once the quota for the Community Mode is sold out, the vouchers will not work anymore.
  • Angels (volunteers) who worked 15 hours or more during 38C3. Angels will receive one voucher per person, which guarantees a ticket for the full duration of the Community Mode phase, even if the other tickets in the Community Mode are sold out earlier. The voucher will replicate once if there are still tickets available – read more on voucher replication below.

Voucher Replication

Voucher replication works like this: If you use your voucher to buy a ticket, you will receive a new voucher once your order is paid. For group vouchers, this will continue until there are no more tickets left, forming a long chain of vouchers. For angel vouchers, this will happen only once, and the replicated voucher will not replicate further.

The replication process takes place once per day, in the evening. It only takes place on days banks are processing payments. An order has to be 24 hours old before it is eligible for replication, even if it is already paid. We decided on this to give a fairer chance to people from abroad (international bank transfers take time), and in order to not push expensive payment methods like credit cards. Also, this way people do not have to wait for the exact moment the vouchers replicate in order to speed up the process (as not everybody can do this, either).

If you apply for a Friends Ticket in the Community Mode, your voucher will behave like you had just bought a ticket. This means that if it is a replicating voucher (Group or initial Angel voucher), you will receive another voucher when the next replication takes place. This is to make sure that your request won’t hold up a voucher chain, even if your conversation with the Friends Ticket team takes a bit longer. Also, this way it is your own decision whether you disclose to your group that you have applied for a Friends Ticket.

Public Presale

The 39C3 presale can be pretty stressful, so here are is an overview of what to expect at the public presale dates:

  1. First off: There’s typically a big rush, especially on the first presale date. You will need to be very punctual (think seconds, not minutes) to buy a ticket during the public presale.
  2. Before the public presale starts, you will see a page letting you know that the presale will start soon. You will not be able to see the full ticket shop page.
  3. The shop opens automatically at the announced time. You will want to (re-)load the ticket shop page at that time. Quality beats quantity: reloading at the correct time matters, whereas the only result of hammering the ticket shop with reloads is a sad and dying ticket shop server.
  4. Once the public presale has started, you will be placed in a queue for the ticket shop. The queue is expected to move slowly, both to protect our servers and to give people who reach the ticket shop some time to purchase tickets. Please be patient and be prepared for the public presale to take some time. In the past, we have seen times ranging roughly from thirty to sixty minutes. We will try to show you an estimated waiting time, but it’s just that: an estimate, and depending on the server load, it may continue to change.
  5. Once you have reached the end of the queue, you will be redirected to the ticket shop. Reaching the ticket shop does not guarantee a ticket, as the last tickets might be sold just as you reach the shop. Upon reaching the shop, you can either:
    1. Purchase your ticket(s). You will be able to put up to two tickets into your shopping cart. In addition, you will be able to purchase up to three Up-and-Coming Tickets (U18). Your shopping cart will be valid for ten minutes. You do not have to pay within these ten minutes, you just have to complete your order.
    2. Instead of purchasing a ticket, you can apply for a Friends Ticket at a reduced price. To do so, scroll down and click the button leading you to the Friends application form. You then have ten minutes to fill in your application (so it might be a good idea to prepare the text in advance). After submitting your application, you are done, and the Friends Team will contact you soon.
  6. The available payment methods are bank transfers and credit card payments. You can change your payment method later, so if you’re encountering problems with your credit card, you can select bank transfer as your payment method in order to complete your purchase, and attempt a credit card payment again later.

FAQ

Community Mode

I was an angel at 38C3. How do I get my voucher?
If you were an angel at 38C3 with the required amount of hours worked, and allowed us to contact you via email, you will receive an email with your voucher code. If you did not allow us to contact you via email, you’ll have to contact us before the Community Mode is sold out.
I was an angel at 38C3 and I have the angel shirt to prove it. Why didn’t I get a voucher?
Angel shirts had a different cutoff than the one we’re using for the vouchers. If you’re sure you worked 15 hours or more, and you didn’t receive a voucher, please contact us before the Community Mode is sold out.
I’m a member of CCC. How do I get my voucher?
For the Community Mode, we give vouchers to active parts of our community – membership itself is not a qualifier. You can read more details in our blog post.
One of our group’s vouchers got leaked / is missing / can’t be used.
The only people with access to a voucher are the people reading the email address receiving the voucher (if a contact email address was provided), and the person who bought the ticket that led to the new voucher’s generation, as the voucher is also displayed on the order page.
I have a voucher. How do I use it?
Your voucher is the key to the ticket shop at tickets.events.ccc.de – scroll to the bottom of the page and enter your voucher code. Each voucher can be redeemed only once, and for one ticket only.
My order is marked as paid, but I didn’t receive a new voucher.
Only orders that are older than 24 hours at the time of replication are eligible for replication. Replication takes place once per day, in the evening, and not during the weekend.

General Questions

I’m a member of the press, a news agency, a documentary filmmaker, etc. Are there press tickets?
Please refer to c3press.de.
How do I buy a ticket?
You can buy a ticket at tickets.events.ccc.de during the public presale dates (see above). Once you’re through the queue, you can buy a ticket. Please note: Experience shows you’ll need to be on time (think seconds, not minutes) to be able to buy a ticket.
I can’t afford a ticket!
We’d love to have you at Congress anyways. After redeeming your Community voucher, or after the queue during the public sale, follow the link at the bottom of the ticket shop page. Write a short message telling us why you’re asking and how much you could pay for a ticket. Please note that during the public sale, you will only have 10 minutes to write this message. The Friends Tickets team will get back to you within a few days.
How many tickets can I buy?
In the open presale, you can buy up to two tickets per cart. We limit cart size to make sure that nobody can snap up all tickets at once. However, Up-and-Coming tickets (U18) do not count towards this limitation, so you can order two regular tickets and as many Up-and-Coming tickets as you need.
I want to bring my kids. Do they need a ticket as well?
Children under the age of 12 can enter the event for free, accompanied by a parent or guardian. For teenagers under the age of 18, we offer the Up-and-Coming tickets at a reduced price.
I’m a disabled person and need a companion. Do they need a ticket as well?
Only you will need a ticket. Your companion can enter the event for free. If you have different companions on different days, please make sure to mention this at the on-site registration.
What’s the difference between the different kinds of Standard/Business tickets?
The difference is how much you’re supporting Congress. We need a higher average ticket price than our minimum price to make the event as awesome as possible. If you buy a ticket for more than the minimum price, you’re also making it possible for us to provide Friends tickets to people who couldn’t afford a ticket otherwise.
Can I work for my ticket? I’ll work XYZ hours!
That’s not how Chaos Communication Congress works: All work is done by participants who have bought a ticket themselves. However, if you can’t afford a ticket, you can request a Friends ticket at a reduced price.
Will there be day passes?
Nope.
Will you sell tickets on-site, once the event starts?
Nope.

Payment and Invoices

How can I pay for my ticket?
We accept bank transfers to our German bank account and credit cards via Stripe.
How long do I have to pay for my ticket?
You have 7 days to pay for your ticket – you’ll find your payment deadline on your order page. Please keep in mind that a wire transfer might take a few days and is only transferred on workdays. If you can’t make the payment deadline, please contact us, or your order will expire.
I paid my ticket, but it’s not marked as paid!
Even with instant bank transfers, banks only really process payments during their working hours / days, so e.g. an instant payment during the weekend will only be properly processed on Monday. If your order has not been marked as paid by the end of the next working day, please contact us.
I don’t need my ticket and I want to re-sell it to somebody else.
We do not support the re-selling of tickets this year, due to the high amount of inflated prices and straight-up fraud going on. If you still want to hand off your ticket, please sell it for no more than you paid for it. You can give your order link or the ticket files to the buyer, as tickets are not personalized.
Somebody wants to sell me their ticket. Is this legit?
Please make sure that you know and trust the seller, as they could just sell the ticket more than once. Please do not pay more than the initial ticket price.
I accidentally gave a wrong transfer reference for my payment. What should I do?
Please contact us. Include the correct transfer reference and what you wrote accidentally instead, as well as the name of the account owner the money comes from. Please DO NOT send a second transfer.
How do I see if my payment has succeeded?
The payment status is shown on your order page. You will also receive an email when your order is marked as paid. Wire transfers can take a couple of days to come through; Credit card payments are processed almost instantly.
I need an invoice for my ticket. How do I get one?
If you ordered a business ticket, you can download your invoice in the ticket shop immediately. For all other tickets, you’ll receive your invoice at a later date close to the event. Please note: In accordance with German law, invoices with a total below €250 will not contain an invoice adress, as they are valid without (“Kleinbetragsrechnung”).
I want to change my invoice address.
You can change your invoice address on the web interface, and then contact us to reissue the updated invoice. Please note, however, that we are not allowed to change the invoice address to an entirely different entity, i.e. a different company. Please keep also in mind that according to German law, invoices with a total below €250 are valid without a recipient address (“Kleinbetragsrechnung”). This means that invoices for orders below that limit will not contain an invoice address.
I want to supply my VAT ID and get an invoice with 0% VAT for reverse charge.
Reverse charge is not applicable. The place of performance is Hamburg, Germany, thus we have to charge German VAT. You can retrieve your VAT via the VAT reimbursement process.
I need the address of the recipient to initiate an international wire transfer.
The address of the account owner is: Chaos Computer Club Veranstaltungsgesellschaft mbH (CCCV GmbH), Marienstraße 11, 10117 Berlin, Germany.
I need the address of your bank to initiate an international wire transfer.
The address of our bank is: Deutsche Postbank AG, Friedrich-Ebert-Allee 114-126, 53113 Bonn, Germany.
The BIC of your bank does not validate in my bank’s web interface.
The 8 letter BIC PBNKDEFF should be sufficient for payment. If your bank insists that it isn’t, you can use PBNKDEFF100 instead.
Where are your terms and conditions / AGB / cancellation policy?
We do not impose any additional or custom terms on the presale, so the German Civil Code (BGB) applies. Likewise, we do not provide a cancellation policy As per § 312g Abs. 2 Nr. 9 BGB.

At the event

How can I download my ticket?
We’ll generate the ticket files shortly before the event. You will receive an email as soon as the tickets are available for download.
I don’t own a printer, how can I present my ticket?
You can present your ticket on a mobile device of your choice. If you do, please turn your display to full brightness in advance. You can also choose to download your ticket in Passbook format, which is supported by various smartphone platforms.
When can I arrive at the event?
The registration desk opening hours will be announced here before the event. We will probably open on December 26th in the evening. Queues can be long on the evening of the 26th and particularly on the morning of the 27th, when everybody is arriving for the Opening at the same time. You can see past waiting times at c3queue.de.
I am an artist, a speaker or a member of the press. Do I go to the registration desk?
There will be separate registration desk for you. Please look out for signs at the entrance!
I can’t stand in line for a long time. Can I get a fast lane ticket?
Our queue is usually moving pretty fast and you shouldn’t have to wait for long. However, if the queue is not an option for you, please approach any of the volunteers managing the queue and we will find a solution for you.
The queue is too overwhelming (noise level, too many people, etc.).
Please approach any of the volunteers managing the queue and they will find a solution for you.
I cannot wear a wristband for medical reasons / because of my job.
Please let the volunteers at the registration know about this. We will still have to close the wristband, so make sure to bring something (like a lanyard) that we can attach it to.
I only need my ticket on two days, can I give it to a friend on the other two days?
No. Once you’ve got your wristband, you can’t share it with others.
I didn’t pay my membership fees / I mistakenly bought a member ticket.
You’ll be able to upgrade your ticket to a standard ticket at the registration when redeeming the ticket. Please make sure to bring the difference in cash.
