Immediately after death send the death certificate copies by certified mail to the three main credit-reporting bureaus. Request that a “deceased alert” be placed on the credit report. Then mail copies as soon as possible to banks, insurers and other financial firms requesting account closure or change of joint ownership. Report the death to the Social Security Administration at 800-772-1213 and the IRS at 800-829-1040. Also notify the DMV. In obituaries, do not include the deceased’s birth date, place of birth, last address or job. Starting a month after the death, check the departed’s credit report at annualcreditreport.com for suspicious activity.
