Cellphone numbers are typically not provided by regional or local phone directories since the numbers are issued and maintained by individual mobile service providers. Cellphone numbers are harder to access or search for through an online directory.
Many national online directories, such as Whitpages or Intelius, offer paid services that may provide cellphone information. A user may perform a free search with an individual's name, address or zip code to generate a listing of possible matches. The listing will include the complete name, address and any listed landline associated with the person. Additionally, one can perform a reverse phone lookup to identify the owner of a particular phone number. Advanced options are offered for a fee, including address history, cellphone and email, background check and social site profiles.
