The Selective Service System (SSS) is a U.S. government agency that has existed for more than a century. Its purpose is to keep track of people who could be called to serve if the country ever needed to bring back the military draft. Even though the United States currently relies on volunteers for its armed forces, the Selective Service system is still kept in place as a precaution.
The agency operates under the Military Selective Service Act, which gives it the authority to collect and manage registration information. Its main responsibility is to make sure that, if a draft is approved by the President and Congress, people can be selected in a way that is organized and fair. It also handles cases where individuals request exemption from military service for religious or personal reasons, offering alternative service options.
A major update to the system is expected soon. In December 2025, President Donald Trump signed a defense bill that changes how registration works. Instead of relying on individuals to remember to sign up, the government will begin enrolling eligible men through its own records. This update is planned to take effect by the end of 2026.
As of now, men between the ages of 18 and 26 are required by law to register shortly after turning 18. Not doing so can lead to penalties, including fines or possible jail time. Registration can also affect access to certain federal opportunities, like jobs or financial aid, depending on the situation. Even with these requirements, not everyone follows through. In 2024, about 81% of eligible men were registered.
The shift to automatic enrollment is meant to make the process more consistent. Rather than depending on individuals to take action, the system will handle it in the background and notify those who are added. There are still some exceptions, such as for people who were continuously hospitalized or incarcerated during the time they would have needed to register.
The United States has not used a draft since 1973, near the end of the Vietnam War. A few years later, in 1980, President Jimmy Carter brought back the requirement for men to register, even though military service remained voluntary.
More recently, global conflicts have led to renewed questions about whether a draft could return. At the moment, there are no official plans to make that happen. Government officials have said it is not currently being considered, but it remains an option if circumstances were to change.
Along with changes to registration, the Selective Service System is also working on updating its technology and adjusting its workforce. These steps are meant to keep the agency prepared in case it is ever needed.
For now, the SSS continues to operate quietly. It does not actively draft people, but it maintains the system so it can be used if necessary.
