While it is true that with other reverse phone search companies people will be notified if somebody searched for their phone numbers, callerbase.com makes your phone search confidential. This gives you peace of mind especially if you’re the one who’s being harassed by annoying telemarketers or prank callers. All you have to do is go to callerbase.com and type in any phone number that has been calling you to the search box and press the "Search" button to get instant access to that phone number's owner information such as name, address, city, state, line type, phone carrier details and more for any United States or Canada phone number.
