Typical advice is to notify Experian (888-397-3742), Equifax (800-685-1111) and TransUnion (800-888-4213) on the death of an individual.
However, is this really needed? The banks seem pretty good at trolling the Social Security Administration reports of deaths, and automatically closing accounts. Would Experian Equifax and TransUnion do any less? Is the typical case "no problem", they got it?
