If you’re trying to complete the Free Application for Federal Student Aid (FAFSA) and receive the error message “Social Security Number (SSN) already in use,” don’t panic. This is a common error that can be easily resolved.

Why Does This Error Occur?
There are two main reasons why you might see this error:
- Duplicate SSN: Your SSN has already been used by another individual on the FAFSA. This could be a mistake by the other person or a result of identity theft.
- Dependent Application: If you are a dependent student and your parent or guardian has already used your SSN on their FAFSA, you will also receive this error.
Resolving the Error
To resolve the error, you will need to contact the Federal Student Aid (FSA) customer service at 1-800-433-3243. A representative will help you determine the cause of the error and guide you through the process of correcting it.
If Your SSN Has Been Misused
If you believe your SSN has been misused by someone else, you should report it immediately to the Social Security Administration (SSA) by calling 1-800-772-1213. You can also file a report online at the SSA website (www.ssa.gov).
If You Are a Dependent Student
If you are a dependent student and your parent or guardian has already used your SSN on their FAFSA, you will need to contact them and request that they remove your SSN from their application. Once they have done this, you will be able to complete your FAFSA using your own SSN.
Other Possible Causes
In some rare cases, this error can also be caused by:
- Incorrect formatting of your SSN
- System glitch with FAFSA website
- Technical issues from the SSA
