All Pennsylvania units bore consecutive volunteer designations. For normal infantry units this designation was the same as its numeric designation. For units of the Reserve Corps and for cavalry and artillery regiments this designation differed, however. The volunteer number of the Ninth Pennsylvania Reserve Infantry was the Thirty-Eighth Pennsylvania Volunteers.
Like almost all Civil War units, the Ninth Pennsylvania Reserve Infantry was often known by an alternate designation derived from the name of its commanding officer. Names of this type used by or for the regiment are shown below.
