Death tracking, for non-social security participants

[Guest Southern FA]

For a governmental DB pension plan which does not participate in Social Security, what are good options to track who is still alive and who is not? This plan has a high percentage of direct deposits.

It is my understanding that survivors, funeral directors, and doctors often report deaths to the Social Security Administration. However, we are concerned with both timeliness and completeness, especially since this public entity does not participate in Social Security. I am expecting that there are private sector providers who consolidate data from multiple sources to supplement the SSA database and provide updates on a monthly basis.
