With local number portability in the United States, it has become increasingly difficult to determine where phone numbers actually go. Is it a landline, cell phone, or VoIP line? If there is a problem reaching the phone number, who do you call to report it? You can now check phone numbers to see which carrier is serving the phone number, as well as retrieve the Local Routing Number (LRN) to see which telephone switch is serving the number within a large metropolitan area with multiple switches.
