I know that it's usually "on team" in AmE. So is it the same with "group". Like if I have to ask someone about his/her group:

I: Which group are you in/on?

Person: I'm not in/on any group.

So should "in" be used or "on" ?

    on a team, on the team and neither have to do with AmE. It's just English. Groups, in for sure. You cannot be "on" a group and this is easily googlable. "on a committee"

  • Strangely, the use of both prepositions together actually has some meaning—even though it wouldn't be common. Which group are you in on? It would mean something like Which group do you have inside information about? Commented Aug 14, 2019 at 5:16

Use "in".

"To be in a group" is the correct form, whether or not it's AmE. We usually don't say "to be on a group".

However, you can use "to be in/on a team". You should look up verbs that collocate with your nouns of choice.
