Whenever I got missed calls with an unknown number, I'll be wondering who called and why. If the person doesn't call back immediately, it'll be on my mind till that person calls again. Don't you just hate that feeling?
If you're staying in the United States or Canada, there's a reverse phone lookup service where you can lookup owner's name and address for any missed calls with unknown phone number. And you can check an unknown number that appeared in your phone bill. This service on LookupByPhone.com is also very useful to trace harassing telemarketers, prank callers and annoying callers.
To find out owner's name, address, carrier, and other details, do a search by phone number. It works for cell phone numbers and unlisted phone numbers. You may have to purchase these information as they are not public record. You don't have to worry about the owner being notified of the search because all the lookups are 100% confidential.
