Lists, Tables, and Directories of Post Offices, 1803

Lists, tables, and directories of Post Offices are available for nearly half of the years from 1803 to 1870, and continuously from 1955 to the present. (For information on the intervening period, see the entry below for the United States Official Postal Guide.) Although there is some variation by year, the earliest lists typically provide an alphabetical listing of Post Office names, along with the name of the postmaster, county and state, and the distances from the Post Office to the state capital and to Washington, D.C. The 1831 Table of Post Offices in the United States provides the first listing of Post Offices by county, which is regularly featured beginning in 1859. Directories of Post Offices from 1955 to 2004 list Post Offices, as well as stations and branches, alphabetically and by state and county, and provide the class of the Post Office (before 1975), as well as names of postal units discontinued in the preceding year. They do not show names of postmasters. Beginning in 1957, numbers of boxes served by Post Offices are listed. City delivery statistics are available beginning in 1979, when the Directory of Post Offices combined with the National ZIP Code Directory to form a new title, the National ZIP Code and Post Office Directory. This was last issued in 2004 as the National Five-Digit ZIP Code and Post Office Directory. Lists of Post Offices by state and county since 1986 are available at http://about.usps.com/who-we-are/postmasterfinder/welcome.htm. (See Postmaster Finder, 1986– .)

Selected editions of the List of Post Offices in the United States, Table of Post Offices in the United States, Directory of Post Offices, and National Five-Digit ZIP Code and Post Office Directory (titles vary slightly) may be available from your local library through inter-library loan.
