Performing reverse lookups and searching the SMS/800 number database are two ways to locate information on 800 numbers. By entering an 800 or toll-free number on a reverse lookup website, you can determine the number's owner.
Users can perform a reverse lookup on 800 and toll-free numbers on websites such as WhitePages.com and ReversePhoneLookup.com to identify the name and location of the person or organization associated with that number.
Users can enter a 800 number into the SMS/800 database maintained on SMS800.com to determine if that number is available. Searching the database can also indicate when a number that is no longer in use is eligible for reassignment.
