  1. Hi! If a PI is trying to see if a young child died in 1980-1985, but she only knows the child’s name and city/county in California she may have died, and doesn’t have authorized permission from the victim’s family or a govt agency, what’s her best course of action for checking to see if there is a death record? Is one allowed to use Ancestry . com or the like? And what explanation might there be for no death record/index if the victim died? Thank you :)

  2. I’m an author and in my current book my PI has a person’s social security number and wants to look up her genealogy using her SS#. In my research of the genealogy web sites, non of them search by SS#. Do PI’s use these search engines and follow the same procedure as a non-PI or do they have a special software program that allows them to search using a SS#?

    Thank you,
    CH Taxdal

    • To search by social security number, private investigators would need access to a background check information provider such as Accurint, LexisNexis, KnowX, etc. See our Background checks page.

      Also, some private detectives are approved to access credit reporting information for business purposes (e.g. background checks, employment checks, debt collections, etc.), which may be searched by SSN.
