If you haven't received a check this month, you should get it this week. Waiting for your October Social Security check to arrive? This Social Security Administration is sending out the final October check this week, so it could come then.

What to Know Before You RetireIf you received Social Security benefits before May 1997, or if you receive both Social Security and SSI, the payment schedule is different. Instead of getting your payments on a Wednesday, you'll receive your Social Security payment on the third day of each month and your SSI on the first day of each month.However, those payment dates change if the first or third day of the month falls on a weekend or a holiday. For instance, July 1 fell on a Saturday this year, so SSI recipients received their July payments a day early, on June 30, and their Social Security payments should have arrived on July 3. If your check doesn't arrive on the date listed above based on your birth date or other circumstances, the Social Security Administration says to wait three additional mailing days before reaching out. If you still haven't received it, you can speak with a representative at 800-772-1213. (The SSA notes that wait times are shorter Wednesday through Friday and between 4 p.m. and 7 p.m. on weekday afternoons.)You can also access your Social Security benefits online.This article is updated monthly as payment dates change.
