No. There is no directory or listing of mobile phone numbers.

There are some sites that you can search a person by his information. Like" White Pages Phone Directory with Free People Search " Hope I can help you.

you can use the advanced search function to search for his questions. I can then go and email or IM said person if they allowed that in their options.

if you mean in yahoo, then yes you can. just ask the person his details and then go to 'FORGET YOUR PASSWORD?' and fill in. then you get the final ques. Ask that too.

yahoo has a 'people search' which you can put the name and state in.  it will come up with any numbers that are listed in regular pages

In Canada you can go to www.canada411.ca and search.  You are actually searching telephone listings.  I suspect the US and other countries have a similar system.  Possibly do a Yahoo people search.  If you just do a search for "find a person" you get lots of interesting links.

Yeah, I like http://www.anywho.com too.  I just tried my number in the reverse look-up and it works...for free.  I've not been able to find a free service that includes look-up for cell phones.

You are able to search on their website.  Just enter your firend's last and first name to check.

Cell phone numbers are, by default, unlisted, so you can't just look up the number.\n\nHowever, you can try looking up the number in ZabaSearch.

Go to Yahoo! People Search.

that's theoretically impossible. unfortunately, even if the person you're looking for registered with their real name and city (which doesn't always happen) i believe email providers are not allowed by law to give out their customers' information.

On your IM, go to contacts, hit VIEW profile, if you know the person's yahoo ID put it in, if it's not there, there is a little thing on top that says PROFILES HOME.  There you can run your search with names, or cities, or just about anything.  I used it many times.
