This service is offered by AT&T, but like the options mentioned in previous posts, is completely free.

1-800-YellowPages is advertiser supported, so you’ll encounter a 5 or 10 second ad when you call. In our opinion, this is a fair tradeoff for a free service.

Another crowd favorite is from none other than one of our favorite companies, Google. With a number that’s also easy to remember, 1-800-GOOG-411, you can use this great “411 service” from any phone, and it’s completely free.

If you’re calling from a mobile device, you can even have GOOG-411 send you a text message with more details and a map. Simply say “Text message” or “Map it”.

Currently GOOG-411 only has listings for businesses. While there is no official word on the inclusion of residential listings, it won’t surprise us at all if Google adds them in the future.
