There is no free printed telephone directory for the entire United States. AT&T and White Pages both operate online directories. Searches can be conducted with these national directories.
While directories are printed and distributed on a local level, not all states require telephone companies to print or provide directories. Alabama, Delaware, Georgia, Indiana, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Texas, Virginia and Wisconsin are states that do not require companies to print or distribute residential telephone listings. Online directories carry listing information for areas in these states that have dropped print listings. Both AT&T and White Pages offer online directories.
