Do telephone number directories publish only landline phone numbers?

Telephone number directories do not publish only landline phone numbers. Directories base their information on whatever phone number the person or business has given them to list.

There are two types of phone directories: Whitepages and Yellow Pages. Whitepages are directories of individual people. Yellow Pages are directories of businesses separated by category, such as restaurants or plumbers. In the United States, the growth of cellphone and Internet phone services like Google Voice make it possible for listings to have phone numbers that are not landline. It is important to note that while listings are numerous, many people choose not to list their information due to the growing concern over privacy.
