What Is the Selective Service System?
The Selective Service System (SSS) is an independent federal agency that maintains a database of men who could potentially be called for military service in a national emergency. It operates separately from the Department of Defense but would work alongside it if Congress and the President ever authorized a draft.
The United States has maintained an all-volunteer military since 1973, when the last draft ended during the Vietnam War. However, Selective Service registration continues as a contingency measure—essentially a backup plan in case voluntary enlistment ever proves insufficient during a major crisis.
Registration with Selective Service does not mean you will be drafted. It simply means your name is in a database that could be used if Congress authorizes conscription. No one has been drafted in over 50 years, and doing so would require significant legislative action.

Automatic Registration: What Changes in December 2026
The FY 2026 National Defense Authorization Act (NDAA) included a major change to how Selective Service registration works. Beginning December 18, 2026, registration will become automatic for most men ages 18-25.
Here’s what this means in practice:
Before December 18, 2026: Men must proactively register within 30 days of their 18th birthday. Failure to register is technically a felony and can result in loss of eligibility for federal employment, job training programs, and various state benefits.
After December 18, 2026: The Selective Service System will automatically identify and register eligible men using existing federal databases, including Social Security Administration records. Men will no longer need to take any action to register, and the penalties for “failing to register” will largely become moot since the government handles it automatically.
This change represents the most significant update to Selective Service law since registration was reinstated in 1980 under President Jimmy Carter (after being suspended by President Gerald Ford). The shift to automatic registration aims to ensure more complete and accurate records while eliminating the burden on individuals to self-register.
After automatic registration takes effect, the SSS will notify men that they have been registered and request any missing contact information. Men who believe they were incorrectly registered (such as those on valid non-immigrant visas) can request to be removed from the system.
Who Must Register for Selective Service
Almost all male U.S. citizens and male immigrants between ages 18 and 25 are required to register. This includes:
- U.S. citizens (including those born abroad to U.S. parents)
- U.S. dual nationals, regardless of where they live
- Legal permanent residents (green card holders)
- Undocumented immigrants residing in the U.S.
- Refugees and asylum seekers
- Men with expired visas (expired more than 30 days)
Residents of U.S. territories including Puerto Rico, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands are U.S. citizens and must register. Citizens of American Samoa who reside in the United States for at least one year must also register.
The registration requirement is based on sex assigned at birth as male, regardless of current gender identity. The Selective Service System provides detailed guidance on specific situations.
Who Is Exempt from Registration
The following groups are not required to register with Selective Service:
- Women: Females are not required to register under current law
- Men on active duty: Those serving continuously in the U.S. Armed Forces from age 18 to 26 (including service academy cadets and midshipmen)
- Non-immigrant visa holders: Foreign nationals in the U.S. on valid student, tourist, diplomatic, or other non-immigrant visas
- Men continuously institutionalized: Those confined to hospitals, nursing homes, or correctional facilities from 30 days before turning 18 until age 26 with no breaks longer than 30 days
- Men born before 1960: Registration was not required for men born before January 1, 1960
National Guard and Reserve members who are not on full-time active duty must register. Men with disabilities who live at home must register—disability alone does not exempt someone from registration, though it may exempt them from service if a draft occurs.
How to Register (Until December 2026)
Until automatic registration takes effect in December 2026, men must register within 30 days of their 18th birthday. Registration remains possible until age 26.
Online: The fastest method is through the Selective Service website. You’ll need your Social Security number and a valid mailing address.
By mail: Pick up a registration form at any U.S. Post Office, complete it, and mail it to the Selective Service System.
Verify your registration: You can confirm your registration status and obtain your Selective Service number through the SSS verification portal. Keep your registration acknowledgment card—you may need proof of registration for federal employment, job training programs, or state benefits.
Penalties for Not Registering
Failing to register with Selective Service when required is technically a federal felony. The potential penalties include:
- Fine of up to $250,000
- Imprisonment for up to 5 years
- Ineligibility for federal employment
- Ineligibility for federal job training programs (Workforce Innovation and Opportunity Act)
- Ineligibility for U.S. citizenship (for immigrant men)
- Loss of state benefits in many states, including state-funded student financial aid and state employment
In practice, no one has been prosecuted for failure to register since 1986. The Department of Justice and Selective Service reportedly agreed in 1988 to suspend prosecutions because they proved counterproductive and difficult to prove as “knowing and willful” violations.

However, the collateral consequences—particularly ineligibility for federal jobs and citizenship—remain real obstacles for non-registrants. Men over 26 who failed to register and need to prove their failure was not knowing and willful can request a Status Information Letter from Selective Service.
Once automatic registration begins in December 2026, these penalties will largely become irrelevant since the government will register men without requiring any action on their part.
What Would Happen If There Was a Draft
There is currently no draft, and reinstating one would require significant steps. Here’s the sequence of events that would need to occur:
1. Congressional Action: A national emergency exceeding the military’s ability to meet personnel needs through volunteers would require Congress to amend the Military Selective Service Act to authorize inductions.
TRENDING: See Today’s VA Loan Rates
2. Presidential Signature: The President would need to sign the legislation into law.
3. Selective Service Activation: The SSS would activate and call up Reserve Force Officers and volunteers to staff local boards and Area Offices.
4. National Lottery: A publicly attended, nationally televised lottery would determine the order in which men are called based on their birthdays.
5. Induction Notices: Men would receive orders to report to a Military Entrance Processing Station (MEPS) for physical, mental, and moral evaluation.
6. Classification and Appeals: Local boards would process claims for deferments, exemptions, and conscientious objector status.
7. First Inductees: According to current planning, the first draftees would be delivered to the military within 193 days of the draft being authorized.
For a detailed breakdown of the draft process, see our guide on how the military draft lottery works.
How the Draft Lottery Works
If a draft were activated, the order of call would be determined by a random lottery—not by registration date or any other factor. Here’s how it works:
The Lottery Process: Two air-mix lottery machines are used. One contains capsules with all 365 (or 366 in leap years) birthdays of the year. The other contains sequence numbers 1 through 365. Capsules are drawn simultaneously from each machine, pairing each birthday with a sequence number.
For example, if August 4 is drawn with sequence number 32, men whose birthday is August 4 would be called after those with sequence numbers 1-31.
Order of Call by Age:
- First called: Men turning 20 during the calendar year of the lottery
- Then: Men turning 21, 22, 23, 24, and 25
- Last: Men who are 19, then those who are 18.5 years old
This means 18 and 19-year-olds would not be called until all eligible men ages 20-25 had been processed. Once a man turns 26, he is no longer subject to the draft.

Deferments and Exemptions from Service
Being called in the lottery doesn’t necessarily mean you’ll serve. Men can file claims for postponements, deferments, or exemptions after receiving an induction notice. These claims are reviewed by local draft boards made up of civilian volunteers.
Postponements (temporary delays):
- High school students: until graduation or age 20, whichever comes first
- College students: until the end of the current semester (or academic year for seniors)
- Emergency circumstances beyond one’s control (family illness, death)
Deferments:
- Hardship: induction would cause extreme hardship to dependents
- Ministerial students: deferred until completion of studies
Exemptions:
- Ministers of religion
- Certain elected officials (while in office)
- Veterans (generally exempt in peacetime draft)
- Sole surviving sons (if parent or sibling died in military service)
- Some immigrants and dual nationals based on residence and citizenship status
- Those found physically, mentally, or morally unfit for service after MEPS evaluation

Conscientious Objector Status
Men who are morally or religiously opposed to war must still register with Selective Service. However, if a draft is activated and they are called, they can file a claim for conscientious objector (CO) status.
Who qualifies: Beliefs qualifying for CO status may be religious, moral, or ethical—but cannot be based on politics, expediency, or self-interest. The person’s lifestyle prior to making the claim must reflect their stated beliefs.
Two types of CO classification:
- 1-A-O: Opposed to combat but willing to serve in a noncombatant role within the military (medical, administrative, etc.)
- 1-O: Opposed to all military service, assigned to the Alternative Service Program
Alternative Service: Conscientious objectors classified as 1-O perform civilian work that contributes to national health, safety, or interest. This includes jobs in conservation, healthcare, education, or caring for the elderly. Length of service equals what they would have served in the military—typically 24 months.
CO claims cannot be filed in advance. They can only be filed after receiving an induction notice if a draft is activated. However, some private organizations maintain programs for conscientious objectors to document their beliefs in writing in case they need evidence later.
Frequently Asked Questions
No. The United States has not had an active draft since 1973. The current military is entirely volunteer-based. Selective Service registration is simply a contingency measure in case a draft is ever needed in the future.
No. Automatic registration is an administrative change to how names are collected, not an activation of the draft. A draft would still require separate legislation passed by Congress and signed by the President. The automatic registration simply ensures more complete records and removes the burden of self-registration.
No. Under current law, only men are required to register. Congress has debated expanding registration to include women, but no such legislation has been enacted. The SSS has stated it is “prepared to expand registration” if directed by law.
Yes. U.S. dual nationals must register regardless of where they live. Those residing outside the U.S. can register using a foreign address through the SSS foreign registration form.
Selective Service registration is based on sex assigned at birth. Individuals assigned male at birth are required to register, regardless of current gender identity. Individuals assigned female at birth are not required to register, even if they later identify as male.
You can no longer register after age 26. If you need to prove your failure to register was not “knowing and willful” (for federal employment or citizenship purposes), you can request a Status Information Letter from Selective Service and provide supporting documentation.
Men with disabilities must still register. However, if a draft occurs, everyone called would undergo physical, mental, and moral evaluation at a Military Entrance Processing Station. Those found unfit for service based on medical conditions would be classified accordingly and not inducted.
No. Conscientious objectors must register with Selective Service. CO status can only be claimed if a draft is activated and you receive an induction notice. At that point, you would file a claim with your local board, appear to explain your beliefs, and if approved, be assigned to alternative civilian service instead of military duty.
Visit the SSS verification portal to check your registration status and obtain your Selective Service number. You may need this for federal job applications, citizenship applications, or state benefits.
Registration simply puts your name in a database. Being drafted means Congress has authorized conscription, a lottery has been held, your number was called, and you’ve been ordered to report for induction. Registration happens to millions of men; a draft has not occurred in over 50 years.
