Your mother's date of birth as reported on your FAFSA does not match her DOB in the SSA records for her SSN. You must correct either her SSN (Item 64) or her DOB (Item 67). If her DOB is correct, confirm by re-entering it in item 67. These corrections can be made at http://www.fafsa.ed.gov. Also, your mother should contact the SSA to make sure that they correct it in their records at 1-800-772-1213 or www.socialsecurity.gov.
