Is there a phone number I can call to find out friends phone numbers?

Question

Sort of like whitepages.com, except on the phone, and you say your friends name and it searches for their phone number, sorta like a phone book.
Also like Toll-free TellMe (1-800-555-1212) Where you say the name of the listing you want and it gives you the phone number. I want something like that, except not searching for listings phone numbers, searching for people's phone numbers.

Answer 1

Have you tried 411? The first two or three per month are free...

Answer 2

I know their house number but I just keep their cell #s in my cell's memory where all I have to do is select their name. And no I do not call numbers written on bathroom walls, mainly because I don't use public restrooms, but on the occasion I do, I still wouldn't call a number wrote on a wall.
