The possibility of a military draft in the United States is low right now, but it is not zero. No one has been conscripted since 1973, and reinstating the draft would require Congress to pass legislation and the President to authorize the process. What still exists is the infrastructure: the Selective Service System keeps a registry of potential draftees, and most young men living in the U.S. are legally required to be part of it. If a national emergency ever demanded more troops than the volunteer force could provide, that system could be activated quickly.
What Would Have to Happen for a Draft to Return
A draft cannot be ordered by a president acting alone. Congress’s power to conscript comes from Article I, Section 8 of the Constitution, which authorizes it to “raise and support Armies,” and the Supreme Court has consistently held that this power includes compelling military service.1Legal Information Institute. Power to Raise and Support an Army: Overview The mechanics sit in the Military Selective Service Act, 50 U.S.C. ยง 3801 et seq.2Selective Service System. About Selective Service
To activate a draft, Congress would need to amend that statute to authorize inductions, and the President would then issue a proclamation starting the process. The Selective Service System’s own planning describes this as something that would only happen during a national emergency severe enough that the all-volunteer force could not meet the country’s defense needs.3Selective Service System. Return to the Draft No administration has asked Congress to take that step in over 50 years.
How Fast a Draft Could Move
If Congress and the President did authorize a draft, the Selective Service has published a timeline. The first inductees would need to report within 193 days of the crisis and the law being updated to authorize conscription.3Selective Service System. Return to the Draft
The Lottery
A national lottery would draw birth dates at random and assign each one a sequence number, setting the order in which registered men receive induction notices. The first group called would be men whose 20th birthday falls in the calendar year of the lottery. If more personnel were needed, later lotteries would work through ages 21, 22, 23, 24, 25, then 19, and finally men at least 18 and a half years old.3Selective Service System. Return to the Draft
Reporting and Screening
Once induction notices go out, registrants report to a local Military Entrance Processing Station for physical, mental, and moral evaluation. Those who pass are inducted. Those who do not meet the standards are sent home. At the same time, local and district appeal boards made up of civilian volunteers start processing claims from registrants seeking deferments, exemptions, or conscientious objector status.3Selective Service System.

Who Is Already on the List
Almost all male U.S. citizens and male immigrants living in the United States who are 18 through 25 are required to register with the Selective Service. That includes naturalized citizens, permanent residents, refugees, asylum seekers, undocumented immigrants, and U.S. dual nationals living abroad. Men on current, valid nonimmigrant visas are generally exempt.4Selective Service System. Who Needs to Register Registration itself does not mean you will be called; it only puts you in the pool if a draft is ever authorized.2Selective Service System. About Selective Service
Women
Only men are required to register. The Supreme Court upheld male-only registration in Rostker v. Goldberg (1981), reasoning that because women were excluded from combat roles at the time, men and women were not similarly situated for draft purposes.5Justia Law. Rostker v. Goldberg, 453 U.S. 57 (1981) The military has since opened all combat roles to women, and the National Commission on Military, National, and Public Service recommended in its 2020 final report that registration be expanded to include women.6Selective Service System.

Transgender Registrants
Registration is based on the sex assigned at birth. A person assigned male at birth who has transitioned to female must still register. A person assigned female at birth who has transitioned to male does not need to register.7Selective Service System. Who Must Register Chart
Ways Out If You Were Called
Not everyone who receives an induction notice would end up in uniform. Federal regulations set out several classifications that can delay or prevent service.
Hardship Deferment
A registrant can be deferred under Class 3-A if induction would cause extreme hardship to dependents who rely on him for support, including a spouse, children, parents, grandparents, or siblings. The deferment lasts no longer than 365 days at a time.8eCFR. 32 CFR 1630.30 – Class 3-A: Registrant Deferred Because of Hardship to Dependents
Ministerial Status
Ordained and regular ministers of religion are exempt under Class 4-D. Students actively preparing for the ministry in a recognized theological or divinity school can receive a Class 2-D deferment while they complete their studies.9eCFR. Part 1630 Classification Rules
Conscientious Objector
A registrant who opposes all military service based on deeply held religious, ethical, or moral beliefs can be classified as a conscientious objector under Class 1-O. The local board evaluates whether the objection is genuine and whether it extends to all forms of combat and noncombatant military service, not just a particular war.10eCFR. 32 CFR 1630.16 – Class 1-O: Conscientious Objector to All Military Service Approved objectors do not simply walk away. They are assigned to 24 months of alternative civilian service in areas like health care, education, environmental programs, or social services.11Selective Service System. Alternative Service Program
Recent Proposals That Could Change the System
Proposals to change the Selective Service System come up regularly in Congress, though none have become law. The two most prominent ideas are expanding registration to women and making registration automatic rather than requiring young men to sign up on their own.
Both the House and Senate Armed Services Committee versions of the FY2025 National Defense Authorization Act included provisions for automatic registration, which would have used existing federal databases to enroll eligible individuals without requiring them to act. Neither provision survived the final bill. The enacted FY2025 NDAA did not include automatic registration, and it did not require women to register.12Congress.gov. FY2025 NDAA: Selective Service Registration Proposals
So the system runs the way it has for decades. Young men must register on their own, the draft remains dormant, and any actual conscription would require Congress to take a step it has not taken since the Vietnam era. The infrastructure exists. Turning it on would be an extraordinary decision reflecting a crisis well beyond what the current volunteer force can handle.
