Do 18 Year Olds Have to Register for the Draft?

Yes. Under federal law, 18-year-old men have to register for the draft within 30 days of their 18th birthday, even though no one has actually been drafted since 1973. The requirement applies to nearly all male U.S. citizens and to most male immigrants living in the United States, and failing to register before age 26 can permanently block you from federal jobs, some state benefits, and, for immigrants, U.S. citizenship.¹

Who Has to Register

The law reaches two groups: every male U.S. citizen between 18 and 26, and every other male person of that age living in the United States.¹ “Male” here refers to the sex assigned at birth. A transgender woman assigned male at birth must register; a transgender man assigned female at birth does not.

Immigration status barely narrows the pool. Permanent residents, refugees, asylees, and undocumented men all have to register. U.S. dual nationals must register within 30 days of turning 18 even if they live abroad, and they can do it online using a foreign address.² The one status-based exception is men in the country on a valid nonimmigrant visa, such as international students or seasonal workers, for as long as they hold that lawful status.¹

For a male immigrant who arrives in the United States between ages 18 and 25, the 30-day clock starts on the date of entry.²

Who Is Exempt

Very few people are. Men on full-time active duty in the armed forces are exempt only if they serve continuously from age 18 through 26. Enlist after your 18th birthday, or leave active duty before 26, and you still have to register. National Guard and Reserve members who are not on full-time active duty are not exempt. Cadets and midshipmen at the service academies are exempt while enrolled.²

Disability by itself does not exempt you. The narrow medical exemption applies only to men who were continuously confined to a hospital, nursing home, long-term care facility, mental institution, or home (unable to leave without medical help) from on or before their 18th birthday through their 26th, with no break of 30 days or longer.³ The same continuous-confinement rule applies to men who were incarcerated during that window: any release of more than 30 days between ages 18 and 25 triggered the registration requirement.² If you think you qualify, you have to provide proof of the confinement dates to Selective Service.

Opposing war for moral or religious reasons is not an exemption from registering. Conscientious objectors still have to register; the claim for objector status is only raised later, if a draft is actually reinstated.⁴

When to Register

You can submit your registration starting 30 days before your 18th birthday and are expected to have it in within 30 days after, a 60-day window centered on the birthday. Missing that window is not fatal on its own. You can still submit a late registration any time before you turn 26.⁵

Age 26 is the hard cutoff. Once you cross it without registering, you cannot register at all, and the consequences described below become permanent. If you are anywhere between 18 and 25 and have not registered, do it today.

How to Register

The quickest route is online at sss.gov/register. You will need your full legal name, home address, date of birth, and Social Security number. Selective Service then mails a Registration Acknowledgment Letter and your Selective Service number to the address you gave.⁶

If you cannot register online or do not have a Social Security number, print SSS Form 1 from the Selective Service website, sign and date it, and mail it in.⁷

Many young men are registered automatically without filling out a separate form. More than 40 states and territories link their driver’s license and state ID applications to Selective Service, so a trip to the DMV can trigger registration. Whether it actually goes through depends on the state’s process, so verify your status at sss.gov/verify rather than assume.

What Happens If You Don’t Register

A knowing and willful failure to register is a federal felony. The Selective Service System states the penalty can include a fine of up to $250,000, imprisonment for up to five years, or both.⁸ Criminal prosecutions have been rare in recent decades. The administrative penalties are what actually hit most people, and they last a lifetime once the age-26 window closes:

Most federal agencies and executive branch positions require proof of Selective Service registration as a condition of hire.⁸
Job training programs funded under the Workforce Innovation and Opportunity Act are closed to men who did not register.⁸
Many states tie their own financial aid, state employment, and professional licensing to Selective Service compliance.⁸
Immigrant men who fail to register face a significant obstacle at naturalization, since the failure can be used as evidence against them in eligibility determinations.⁸

One consequence has been removed. Federal student aid, including Pell Grants and Direct Loans, no longer requires Selective Service registration. The FAFSA Simplification Act took that requirement off the table starting with the 2023-2024 award year.⁹ State-funded aid programs may still require it, depending on where you live.

If You Are Already Past 26

If you are 26 or older and never registered, you cannot fix the registration itself. What you can do is request a Status Information Letter from Selective Service. The SIL documents your registration status and is what employers, federal agencies, and benefit providers ask for when they need to verify whether you were required to register.¹⁰

The letter does not forgive the failure. What matters is whether the agency reviewing your case concludes your failure was “knowing and willful.” Selective Service does not make that call; the official handling your application does, whether that is a financial aid officer, an HR staffer, or an immigration adjudicator. Documentation that you were incarcerated, hospitalized, or living outside the country can support a finding in your favor, and active-duty military service is considered particularly strong evidence that the failure was not deliberate.¹¹

Immigrant men who are 31 or older applying for naturalization no longer need to provide a SIL or Selective Service documentation to USCIS unless USCIS specifically asks for it.¹⁰
