With 030 you call Berlin. With 030.berlin you hear the city.

030.berlin is an open voice channel for people in Berlin: push to talk, release to listen. No sign-up, no profile, no setup – the principles of CB radio, adapted for the browser. The name is no accident: 030 has meant Berlin for decades.

What does 030 mean?

030 is Berlin's dialing code, the city's area code. From abroad you dial +49 30. A short number that people across Germany instantly connect with Berlin – and still the code for every landline call into the city today.

Its shortness follows a pattern. The first digit stands roughly for a region: Berlin sits in the east on 3, between the Rhineland on 2 and the north on 4. Within each, the most important cities were given the shortest, two-digit codes. Hence 030 – not 020 or 040.

From dialing code to open channel

030 connects telephone lines in Berlin. 030.berlin carries the same idea – local reachability – into open conversation: people who are in the same place, at the same moment. Not a call to a single number, but open channels where the city can be heard.

What is 030.berlin for?

For the moment when something is happening: asking which queue is shorter, saying when the doors open, hearing what is going on nearby – before a concert, at a street festival, at the flea market, in your Kiez. One channel per district, plus channel 9 for the whole city.

Why no sign-up?

Local communication does not have to be yet another app, another account, another social network. Sometimes all it takes is a channel that is simply there: open it, listen, say something. No archive, no history, nobody collects followers.

Berlin is on the air.
