Ever miss a call and wonder who that phone number belongs to? Find the owner of any phone number with this simple search tool on your iPhone or iPod touch by typing in the phone number you want to trace. A map of the location and details of the phone line itself are returned to you. The free information is limited to the location of the phone number and what type of line it’s on.

Note: To find out the owner information, you will need to progress onto the commerical phone trace which costs from $15. Try with TestiPhone
