We should be notified imediately once a person dies; but you can't apply online for survivor benefits.
Do you need to report a death or apply for benefits?
Yes, I need to report a death or apply for benefits.
Then you need to call 1800-772-1213 TTY 1-800-325-0778 and speak to a Social Security representative from 7 a.m. and 7 p.m. Monday through Friday. Or you can visit your local Social Security office.
