A mobile phone number is rarely listed in the phone book unless the person you are looking for owns a business and requested it be placed in the book. In order to find a mobile phone number, you will have to look elsewhere. A mobile phone number can usually be obtained simply by asking or locating another person who knows the individual. However, in extreme cases, a private investigator can be hired to find someone's mobile phone number for you.

  1. 1

    Type the name of the person into an Internet search engine. Sometimes, but not often, you can scroll through the results and find the person and his contact information.

  2. 2

    Ask other people you think may know the person. They may give you the number or let you know someone who might have it.

  3. 3

    Go to a mobile phone number directory or reverse lookup website. These sites may charge a fee to provide a mobile phone number, but if it is very important that you have the number, this may be worth it to you.

  4. 4

    Call other phone numbers you have for the person. Sometimes a person will forward his landline or work line to his mobile phone and you can contact him that way. Other times, the person may leave a message on those lines letting callers know what his mobile number is.

  5. 5

    Use social media websites to locate the person and find his number. People often post their mobile number in their profile or send it as a publicly available message to their friends.
