A good strategy for asking a girl for her phone number is for the guy to wait until the end of the conversation and then tell her he enjoyed the conversation and would like to continue it sometime, advises Made Man. Another idea is to tell her he is new in town and is trying to get to know local people. After getting the number, he can admit it was a pickup line because he really likes her.
If the guy is lucky, the girl finds it flattering that he was so interested in her that he used the, "I'm new in town," pickup line to get her number, according to Man Made. If the guy is uncomfortable telling this fib, another option is to hand the girl his number instead in hopes that she returns the favor. A more romantic and direct approach is to give her a rose with a card attached that reads, "Might I be so lucky as to have your number?"
A guy can increase his chances of getting a girl's phone number by having his phone out with his contacts screen already loaded, according to The Art of Charm. This makes it easy for her to grab the phone and type in her number. While she is typing in her number, the guy can casually mention some ideas for where they can go on a first date based on their shared interests.
