Most states, including the states of Illinois and Florida, operate telephone directories for listed numbers where a person can start a reverse directory search.

For people who may wish to look up phone numbers dating back from the 19th and 20th centuries, the Library of Congress Business Reference Service holds a substantial amount of historical reverse telephone and address directories.
