If you meet someone you like, make plans to meet in a coffee shop, at a restaurant, or at an amusement park, rather than giving out your home address or place of work. [4]

Don't mention exactly where you live, even in passing.

Giving out your cell phone number is okay if you want to. The main idea is that you take time to really know this person and get a feel for the real guy or girl, not just that first impression.

Though making new friends is part of the fun of going out, you should avoid giving too much personal information to someone you just met, unless that person has been vouched for -- like if she's the best friend of one of your best friends. But even then, be on the look out. Do not mention that you came alone. Say you are waiting for friends to arrive or someone is picking you up soon.
