Toll-free directory assistance and toll-free number directories on websites such as TollFreeNumber.org and TollFreeDA.com are some places to find 800 numbers. Callers can obtain 800 numbers assigned to people and organizations by calling toll-free directory assistance at 800-555-1212.
Websites such as Inter800.com and 800-Numbers.net contain databases to help users find 800 numbers. Sites such as TollFreeDA.com and 800Notes.com allow users to perform reverse look-up searches by number to determine the person or organization assigned to an 800 number, in addition to standard business listing searches by name.
Businesses and individuals trying to find an 800 number for the purpose of purchasing one should consult a service provider known as a RespOrg. These service providers have access to the SMS-800 database that assigns toll-free numbers. The database at SMS800.com is also helpful to determine whether a desired number is available.
