Does it mean anything if a girl asks for your number?

This week I met some separate girls on different occasions, after meeting for the first time we either hung out or chatted. Before I said goodbye and they asked for my contact info, I gave them my number, but does it mean anything? Are they gonna call? Is it a sign that they might have interest in me?
