What in the HECK is My DLI and Why Does It Matter?

If you are trying to get Social Security Disability Insurance (SSDI), I want you to know something very important. It is called your “Date Last Insured,” or DLI.

Your DLI is the last day you are covered for SSDI. I like to think of it as a deadline. To get benefits, you must show that your disability started on or before that date. If you became disabled after your DLI, you may not qualify for SSDI, even if you are very sick now.

I know this can be confusing. Many people do not know their DLI or why it matters. They may file a claim too late or not have the right proof. This can cause them to lose benefits they could have received.
