Is there a limit to the number of channels I can add to a single channel group?

Channel groups are limited to 400kB in size. The number of channels you can add to a channel group depends on your average channel name length. PubNub supports channel names consisting of up to 92 characters, allowing you to add at least 4000 channels inside a channel group. If your average channel name length is shorter, you will be able to add more channels.
