I tend to focus on searching for places with a what / where search–the where being a latitude / longitude, address, zip code, neighborhood and metro area. But there is another quick way to search for a business, using the phone number.

All you have to provide is the phone number minus and dashes, spaces or other special characters, the client IP address and your publisher code.
It’s a pretty quick and dirty way to do a search for a business if you don’t know the location.
