Like every large organisation the Chaos Computer Club doesn’t get by
some bureaucracy. The
[office](mailto:office@ccc.de "Chaos Computer Club Office") manages all
your matters regarding your membership or Datenschleuder subscription.

From the office, to identify you easily, you’ll get a small (at the time
5 digit) number assigned. We call this number Chaosnummer (chaos
number). Once you became a member the office will make sure that your
name appears on your designated Datenschleuder and the cash desks at the
[Congresses](http://events.ccc.de/congress/ "Chaos Communication Congress")
and [Camps](http://events.ccc.de/camp/ "Chaos Communication Camp") know
to give you a discount. If you let the payments slide for too long the
office might send you friendly payment reminders as well.

You can get in touch with the office via e-mail at <office@ccc.de>, and
we recommend – as for any e-mail communication – to encrypt your e-mails
to us using
[PGP](http://en.wikipedia.org/wiki/Pretty_Good_Privacy "PGP") ([our
key](/system/uploads/296/original/Office-2020.asc "office PGP key for 2020")).
The current key’s fingerprint is:

    pub   rsa4096 2020-03-21 [SC] [expires: 2021-03-31]
          6AB9 FA18 C850 249A 9A3B  1909 B3BB 04F8 5A88 3447
