Service number (United States Marine Corps)

Service numbers upwards to 49,999 were also retroactive and assigned to discharged or retired Marines who had served between 1905 and 1917.

The enlisted service numbers between 50,000 and 60,000 were never assigned by the Marine Corps for reasons which are unclear.

The first group, ranging numbers 350,000 to 670,899, were standard Marine Corps enlistees joining for wartime service.

Until the middle of World War II, the remaining service number range of 800,000 to 999,999 was used by regular Marine enlistees.
