How to Ask for a Girl's Phone Number

Instructions

Brief Encounter
1
Take chances. Brief encounters are times when you may only get one chance to talk to a woman. Maybe it's in line at the supermarket, sitting in a cafe or in the hallway at school. The key to these encounters is confidence. Stand or sit straight, make eye contact, smile and be friendly. Practice these habits at home or with friends you're already comfortable with. You don't have to tell your friends, just make a point to make eye contact or to walk a little bit taller each day.
2
Keep it simple. In most situations, you will want to start a small conversation before asking for a girl's number. You can often determine some topics from your surroundings. Are you pumping gas at a gas station? You can comment on her car, the traffic, gas prices or even the weather. If you're at school, try asking what classes she's taking or simply comment on your surroundings. There are unlimited potential questions, so be original.

Continue the conversation. Seeing as this is only a brief encounter, your conversation won't be able to last very long. Luckily, this can be used to your advantage. If the two of you had a good conversation for only 30 seconds, it's likely she'll want to know more. Now's a good time to ask for her phone number. You can't chat about the tabloids in line at the supermarket all day, so what better way to continue the conversation than over the telephone or dinner.
Ongoing Friendships
1
Talk with acquaintances. Ongoing friendships are relationships where you see the girl frequently and don't have a strict time limit to get the number. Rather than conversation and confidence, the key to these situations is a mild friendship. Joke around with the girl as you would one of your friends and act as naturally as you can. Try to remember that this girl is just another person and she does normal people things. She goes home at the end of the day and watches TV, she gets bored and she has fears. Even if you aren't the greatest conversationalist, she'll have times to pick up on your other qualities.
2
Make sure to hint about your romantic interest as well as gaining friendship. Flirting techniques, such as subtle touches to her hands, are a great way to accomplish this goal.
3
See if the girl returns your flirtatious behavior. If so, it's likely you'll be able to successfully ask for her number. Find something the two of you have in common, such as an activity you would both like to participate in. After suggesting that the two of you do this activity together, you'll have an excuse to ask for her number. This takes a lot of pressure off of the question and makes the exchange more natural.

Try asking for her instant messenger name or email address if Step 3 is simply too much to handle. You could even befriend her on a social networking website and begin talking there. The Internet provides a variety of tools to make this question easier.
