Date Last Insured
The last date a person met the Social Security work credit requirements to be insured for SSDI benefits. Your disability must have begun on or before this date to qualify for SSDI.
Typically calculated as the date through which you had 20 qualifying work credits in the last 10 years.
If you stopped working years ago and your DLI has passed, you may only be eligible for SSI, not SSDI.
