How long after meeting someone can you ask for a phone number? Would you see it as flirting?

Really depends; if you are doing direct assaul... eeerr, I mean daygame to strangers then you have to ask for their number because otherwise you will never see them again. Not unless the girls attack you and it becomes a police matter.
Other wise I would say hold it off for a few days and try to gauge her reaction to you and so on. And be very careful about it0
