Determine when your Social Security check should arrive based on the schedule provided by the Social Security Administration. If you have been receiving checks since before 1997, your check should arrive on the third of the month. If your birthday is from the first to the 10th, your check should arrive on the second Wednesday. Birthdays between the 10th and the 20th have Social Security checks mailed on the third Wednesday. A birthday from the 20th to the end of the month has a fourth Wednesday mailing date. Supplemental Security Income checks arrive on the first of the month.
Wait three days beyond the date when your check should arrive.
Contact the Social Security Administration at the main number, 800-772-1213, and report non-receipt of your Social Security check. They can track and find it for you. For those with hearing impairments, the toll-free TTY number is 800-325-0778.
