You can complete your Selective Service registration online in about five minutes at sss.gov. Federal law requires most men living in the United States to register between ages 18 and 25, and the agency’s web form is the fastest way to do it. The registration window opens 30 days before your 18th birthday, and you’re expected to register within roughly 60 days of turning 18, though the door stays open until you turn 26.1Office of the Law Revision Counsel. 50 USC 3802 – Registration
Before You Open the Form
Have four pieces of information in front of you:
- Your full legal name, spelled exactly as it appears on your government-issued ID. Mismatches with what other federal agencies have on file cause processing errors.
- Your Social Security number. This is the primary identifier the system uses, so check every digit.
- Your date of birth. The system uses it to confirm you fall inside the 18-to-25 age range.
- A current mailing address. Selective Service sends your acknowledgement letter and registration card to whatever address you provide.
The online form only works if you have a Social Security number. If you don’t, skip ahead to the paper option below.
One quick check before you fill anything out: you may already be registered without knowing it. More than 40 states and territories link their driver’s license and state ID applications to Selective Service, either registering eligible men automatically or offering the option at the counter. If you got a license or state ID as a male between 18 and 25, use the verification tool at sss.gov to look up your status before submitting a new registration.
Step by Step at sss.gov
Go to sss.gov and click the registration link. Enter your name, Social Security number, date of birth, and mailing address on the form.2Selective Service System. Register A review screen then lets you verify everything before you finalize. Check the box providing your electronic signature — you’re certifying the information is true and correct — and click submit.
If the system accepts your entry, a confirmation page loads immediately with a unique confirmation number. Save it or print it. That page is your temporary proof of registration until your official documents arrive.
After You Submit
Within 90 days, Selective Service mails you three things: an acknowledgement letter, a registration card with your assigned Selective Service number, and a change-of-information form.3Selective Service System. Proof of Registration Keep the card with your important documents. You may need the number years later for federal jobs, certain state benefits, or a naturalization application.
If 90 days pass and nothing arrives, call the Selective Service System at 847-688-6888. The automated line can give you your Selective Service number directly.3Selective Service System.

Until January 1 of the year you turn 26, you’re required to notify Selective Service of any address change within 10 days of moving. Use the update form on sss.gov. Once you turn 26, that obligation ends.5Selective Service System. Update Your Information If you legally change your name at any point while the registration requirement applies, report the change within 10 days as well.
If You’re Late but Still Under 26
You can register online at any point before your 26th birthday, even if the 30-day window after you turned 18 is long gone.6Selective Service System. Frequently Asked Questions The process is exactly the same. Registering late is always better than never registering, because once you turn 26, the window closes permanently.
If You Can’t Use the Online Form
Without a Social Security number, the online portal won’t accept your registration. Pick up SSS Form 1 at any U.S. post office or download it from sss.gov, fill it out, sign it, and mail it to:2Selective Service System. Register

Paper registration takes longer to process, so expect a longer wait for your acknowledgement letter.
If you’re already 26 or older and never registered, the online form won’t work either — the window has closed. What you can do is request a Status Information Letter from Selective Service. The SIL is an official letter documenting whether you were required to register and whether you did.7Selective Service System. Request a Status Information Letter It doesn’t forgive a missed registration. It just documents the facts so the federal agency, state office, or USCIS officer reviewing your file can decide whether the failure was knowing and willful.8Selective Service System. Status Information Letter Immigrant men aged 31 or older applying for naturalization no longer need to provide a SIL to USCIS.
Who the Requirement Covers
The Military Selective Service Act reaches most male U.S. citizens and most male non-citizens living in the country between 18 and 26.1Office of the Law Revision Counsel. 50 USC 3802 – Registration That includes permanent residents, refugees, asylum seekers, parolees, and undocumented immigrants. Dual citizens must register regardless of whether they live in the U.S. or abroad, and those overseas can register with a foreign address on sss.gov.9Selective Service System. Who Needs to Register Men who object to military service on moral or religious grounds still have to register; a conscientious objector claim can only be filed later, if a draft is activated and you receive an order to report.10Selective Service System. Conscientious Objectors
The requirement is based on sex assigned at birth. People assigned male at birth must register even if they have transitioned or legally changed their gender. People assigned female at birth are not required to register.
A few groups are exempt: foreign nationals in the U.S. on valid non-immigrant visas who keep that status until 26, men on continuous full-time active duty from 18 to 26, and men continuously institutionalized or incarcerated with no break of 30 days or more across that entire window.9Selective Service System.

Why It’s Worth Doing Now
Knowingly failing to register is a federal felony punishable by up to five years in prison and a fine.11Office of the Law Revision Counsel. 50 USC 3811 – Offenses and Penalties The federal government has not prosecuted anyone for it since the 1980s, but the downstream consequences are enforced routinely.
Federal executive branch agencies generally require Selective Service registration as a condition of employment, so a missed registration can get a federal job application rejected outright.12USAJOBS Help Center. Selective Service Registration Many state and local government jobs impose the same rule. For immigrants seeking citizenship, USCIS reviews whether you registered on time; a failure can raise questions about good moral character and delay or derail a naturalization case.
Five minutes at sss.gov today prevents a much longer conversation with a hiring officer or an immigration officer later.
