Most people assume the World War II draft began the day after Pearl Harbor. It didn’t. The United States started conscripting men more than a year before it entered the war, and the rules that governed who got called up changed dramatically once it did. Whether you’d have gone depends heavily on which version of the draft you’re asking about.
The First Peacetime Draft in American History
On Sept. 16, 1940, with France already fallen and Britain under siege, President Franklin Roosevelt signed the Selective Training and Service Act, commonly called the Burke-Wadsworth Act. It required all men between 21 and 36 to register with local draft boards, the first time the country had ever conscripted troops while technically at peace. Registrants selected by lottery served one year of training and were legally barred from serving outside the Western Hemisphere, a restriction that reflected how unwilling Congress still was to commit to a foreign war.
Blindfolded with a strip of cloth cut from a chair used during the signing of the Declaration of Independence, Secretary of War Henry Stimson drew the very first draft number, 158, on Oct. 29, 1940.
Everything Changed on Dec. 7, 1941
The Japanese attack on Pearl Harbor didn’t just bring the United States into the war; it rewrote the draft entirely. The one-year service limit disappeared; men now served for the duration of the war plus six months. The restriction against serving outside the hemisphere was gone. And the age range expanded enormously: Registration was required of all men ages 18 to 65, while actual induction eligibility ran from 18 to 45.
That’s the detail that matters most if you’re trying to figure out where you’d have landed. Turning 21 in 1940 put you in the very first registration and training cycle, months before the U.S. was even at war. Turning 18 in 1943 put you squarely in the pool at the height of the fighting, with the country actively pulling in every eligible man it could find.
Who Actually Got a Deferment
Not everyone eligible by age went. Local draft boards — the same decentralized system used in World War I — could grant deferments for men working in occupations deemed essential to the war effort: agriculture, shipbuilding, aircraft manufacturing, mining, and similar industries. Married men, especially those with children, initially received deferments too, though as the war ground on and manpower needs grew, that protection weakened considerably by 1943 and 1944. Conscientious objectors were, for the first time under federal law, given an official path to alternative service instead of combat.

The Scale of It
By the time the war ended in 1945, roughly 50 million men between 18 and 45 had registered with the Selective Service System, and about 10 million had actually been inducted into an armed force that peaked at around 15 million total, including volunteers. Public opinion surveys throughout the war consistently found that most Americans viewed the draft as fair, a strikingly different reaction than the bitterness that had surrounded conscription during the Civil War and, later, Vietnam.
So: if you were a healthy 18- to 45-year-old man without a deferment-worthy occupation or a large dependent family, your odds of induction were very high, especially after 1942. If you were a skilled worker in a shipyard or an aircraft plant, or a farmer feeding the war effort, you might have spent the war stateside despite being perfectly eligible on paper. And as in the first war, women were not subject to conscription at all, regardless of age, though hundreds of thousands volunteered for military service through programs such as the Women’s Army Corps (WAC) and the Navy’s WAVES (Women Accepted for Volunteer Emergency Service).
