Google 411 has been discontinued, but 1-800-FREE411 is still around.

You can find and be connected to any business for FREE by dialing 800-GOOG-411.  Say “details” during your call, and you will be read the number and address.  Say “text message”, and you’ll get a text with the details.  Amazing!

For residential listings, try 800-FREE411.

More free services can be found in an article (which you can read for free) by David Pogue on the New York Times website.
