Fillable Registration Form

If you have a social security number and you are not able to register online, or if you do not have a social security number, or if you are an immigrant male (documented or undocumented) age 18 through 25, please complete the fillable registration form here.

You may complete this fillable registration form, print, sign, and mail to:

Selective Service System
P.O. Box 94739
Palatine, IL 60094-4739


NOTE: This is a secure site. The information you provide on this form is protected as it travels to Selective Service over the internet.

Information Collected on the Registration Form

The only information a man provides when he registers with Selective Service is his:

  • Full name
  • Date of birth
  • Gender
  • Social security number, if he has one, and
  • Current mailing address

What Happens After You Complete a Registration Form?

You are not officially registered until your registration information is entered into Selective Service registration file and you have been assigned a Selective Service registration number.

Then, you will receive in the mail a registration acknowledgment letter with your card showing the information recorded in your file, your Selective Service registration number, and a change of information form. If any of the information on your registration acknowledgment card is incorrect, it is important that you correct it and mail the change of information form back to Selective Service. This registration acknowledgment card is your proof of registration with the Selective Service System. Keep this important document in your permanent files for future reference.

NOTE:  If you do not receive a registration acknowledgement letter within 90 days, it is your responsibility to contact the Selective Service at 847-688-6888.

Register to be eligible for benefits and programs linked to the registration requirement — Men who have registered with Selective Service remain eligible for federal student financial aid, state-funded student financial aid in many states, most federal employment and some state employment, job training under the Workforce Innovation and Opportunity Act (formerly known as the Workforce Investment Act), security clearances, and U.S. citizenship for immigrant men.

For more information, see WHY REGISTER.

MEN 26 Years Old and Older 

Once a man reaches his 26th birthday, Selective Service cannot register him.  Go to our webpage for MEN 26 AND OLDER.

Immigrant Men, 18 - 25 (Documented or Undocumented)

The Selective Service System has not now, or in the past, collected or shared any information which would indicate a man's immigration status, either documented or undocumented. Selective Service has no authority to collect such information, has no use for it, and it is irrelevant to the registration requirement. Consequently, there is no immigration data to share with anyone.


Immigrant Men Are Required to Register

With very few exceptions, all males between ages 18 and 25 must register with the Selective Service System (SSS) within 30 days of arriving in the United States. This includes U.S. born and naturalized citizens, parolees, undocumented immigrants, legal permanent residents, asylum seekers, refugees, and all males with visas of any kind which expired more than 30 days ago. The few individuals who are exempt from this requirement are those on current non-immigrant visas. A complete list of acceptable documentation for exemption may be found here.

Immigrant Men 31 or older 

Immigrant men over the age of 31 who are seeking naturalization and who did not register are no longer required to provide a "status information letter" or documentation of their status from Selective Service to USCIS. If asked for a "status information letter," these men may print a form letter concerning their request for a letter for use with USCIS HERE.


Selective Service accepts early registrations as young as 17 years and 3 months.

If we have your social security number in our system, you can register online at the top. If not, you can complete a fillable registration form above. Then, print the form, sign and date, and mail in. Or, you can complete a Selective Service registration form (SSS Form 1) available at your local U.S. Post Office to fill out, sign and date, and mail in.

If you should register early, Selective Service will hold your information until 30 days before your 18th birthday. At that time, we will process your registration and you will receive a registration acknowledgment card in the mail to confirm your Selective Service registration and for you to check that all your information listed is correct.


Intentional submission of false information using this Federal Government Internet website, or purposefully submitting a registration for a man without his knowledge and consent, is illegal. Persons found guilty of knowingly submitting fraudulent registration information may be prosecuted and, upon conviction, may be subject to a fine of not more than $250,000 and/or imprisonment not to exceed five years.
