The Postmaster Finder contains basic information about many local Post Offices™ and Postmasters. It includes:

  • Most Postmasters appointed after 1986
  • Some Postmasters appointed before 1986.
  • Over 12,000 Post Offices (with the number increasing).

You can access the Postmaster Finder on the internet.

For information prior to 1971, the primary sources of information are the National Archives Microfilm Publication M1131, Record of Appointment of Postmasters, October 1789 - 1832, and M841, Record of Appointment of Postmasters, 1832 - September 30, 1971. The Postal Bulletin, the Official Register of the United States, and the Journals of the Postmaster General, along with various lists, tables, and directories of Post Offices, are sometimes used in conjunction with the Record of Appointment of Postmasters.

From 1971 to 1986, information is pulled from record cards of postmaster appointments located in the USPS Historian's office.

Since 1986, information in Postmaster Finder has been updated from PS Forms 2030 and 8020, Report of Installation (Postmaster or Officer-In-Charge), completed by field personnel; postmaster appointment lists compiled by Human Resources; and the Post Office Changes sections in issues of the Postal Bulletin

My ancestor was a Postmaster. Why are they not in Postmaster Finder?

Postmaster Finder contains only some of the information that is available prior to 1986. Additional data is continually being added.  However, it will take a number of years to research every Post Office.

How can I get information on a Postmaster or a Post Office that is not in Postmaster Finder?

  • The National Archives will provide information on postmasters and Post Office facilities prior to 1971 upon request.
  • Information after 1971 can be obtained from the United States Postal Service Historian.

Additionally, historians have compiled books on Post Offices for many states, some of which include postmasters' names and appointment dates. Your local library should be able to assist you in obtaining these.
