Hey...I'm moving to NYC after graduation and thinking about getting a new cell phone with the 646 area code.

My current hometown is in Beverly Hills (no, I'm not a richboy) which is a 310 area code. But the 310 probably makes people THINK im related to someone famous haha.

Should I switch to 646 upon moving to NYC? I mean, it's nothing like 212 that's for sure. Or do New Yorkers know about the 310 area code as well?
