Things You'll Need

Instructions

1

Call your cell phone provider and ask the representative to trace the number for you if it's coming into your cell phone. Many providers will do this for their customers if the calls come repeatedly or if they're threatening in nature.
2

Visit the Free Cell Phone Lookups website. This website will allow you to search for cell phone owners by first entering the cell phone number in the directory.
3

Enter the cell phone in one of the popular search engines such as Google--include the entire number and ZIP code, if you know it. Sometimes numbers are listed on other websites from people wondering who owns the number.
4

Return the phone call yourself and ask the person why he called. This is obviously the best way to locate the person who has been calling you and it only takes a few minutes.
