NOTE: As of January 2008, multiple readers have reported that the reverse lookup feature does not seem to be supported by Google anymore. I'll update with more information on Google's reverse lookup service as I get it. - Wendy
You can do a free reverse lookup with Google - it's fast and pretty simple. Here's how you do it:503 555 1212 or phonebook: 503 555 1212
The search syntax requires that you have the area code and spaces between the blocks of numbers; it DOES matter if you put the hyphens in there, so don't do it. The "phonebook" operator searches both the business and residential listings for whatever phone number you put in. In addition, if you don't want your phone number listed in the Google Phonebook directory, you can visit the Google Phonebook Name Removal page to have it removed.
Either method works just fine here; you are also given the option of searching Google Maps for the address that comes back with the phone number you have just looked up.
