If specific criteria are met, receipt of any version of an SSA-3820 (3820) by SSA
may constitute a writing that protects a date of filing for Title XVI benefits for
a child. Follow the guidelines in SI 00601.012 through SI 00601.025 to determine the filing date.
When the IU establishes an i3820 partial, the system tells the IU that the date the
IU started the i3820 is a protective filing date. At that time, the i3820 also issues
a closeout notice on the webpage. The closeout notice gives the date by which the
IU must submit the i3820 to SSA. Failure to submit it by the end of the closeout period
results in loss of the protective filing date. If the IU submits the i3820 after the
protective period expires, the date of submission becomes the new protective filing
The closeout period starts with the date the user establishes the i3820 partial. The
closeout period ends 60 days later. The close out period does not change if an IU
establishes a subsequent i3820 partial prior to submission of the first. The original
protective filing date applies. Starting a second partial locks the first, making
it inaccessible to the IU.
