Question: how do i know if my social security check has been mailed?
Answer: If you can't find the office online, call the Social Security Administration's main line at 800-772-1213. Live assistance is available from 7 a.m. to 7 p.m. Monday through Friday in all time zones. Ask if your SSI check has been sent and when it was mailed. Have your Social Security number on hand when you call.
