Americans are getting older, but not this old: Social Security records show that 6.5 million people in the US have reached the ripe old age of 112. In reality, only few could possibly be alive. As of last fall, there were only 42 people known to be that old in the entire world.

But Social Security does not have death records for millions of people, with the oldest born in 1869, according to a report by the agency’s inspector general.

Only 13 of the people are still getting Social Security benefits, the report said. But for others Social Security numbers are still active, so a number could be used to report wages, open bank accounts, obtain credit cards or claim fraudulent tax refunds.

“That is a real problem,” said Senator Ron Johnson, a Republican from Wisconsin. “When you have a fake Social Security number, that’s what allows you to fraudulently do all kinds things, claim things like the earned income tax credit or other tax benefits.”
