You can apply for survivor's benefits at your local SSA office or by calling Social Security at 800-772-1213 to make an appointment. There is no online application option. If you provided the deceased person's Social Security number to the funeral home, they will have reported the death to Social Security. Otherwise, you can report the death by calling 800-772-1213.
More information can be found on the SSA website. SSA has an online tool that you can use to find out if you could be eligible for benefits from any of the programs that Social Security administers.
