Social Security’s regulations assume that any notices they mail to claimants will be received within five days. I think many of us have recently had personal experiences with the unreliability of the U.S. mail. For example on January 4 I received a package that was sent to me by U.S. mail on December 4. As another example, well into the new year I was still receiving Christmas cards mailed to me a week or more before Christmas. For another example, I’ve already had at least one payment I mailed received late even though it was mailed more than a week before the due date. You can add your own examples.
There is only a limited time given to file appeals from adverse Social Security decisions. There is only an extremely short time given to ask for interim benefits when a person is told they are no longer disabled. I think it’s time for Social Security to revisit its assumptions about mail service.
