One thing people forget is that Lexis-Nexis is hardly the first company to offer this kind of service. Several years ago, there was a controversy when Lotus planned to offer this kind of information on CD-ROM. The main competition of Lexis-Nexis, West Publishing Company ("Westlaw"), offered this kind of service before Lexis did. The last I heard, it was possible to get SSNs via Westlaw. I don't know if this is still true. I checked with a friend of mine, and got this response: "Westlaw offers access to several databases (including its PEOPLE-CB and INFOAM databases). They provide a person's "Credit Bureau Header," which contains social security number, previous address(s), telephone number(s), spouse name, date of birth, related names/aliases, and the date the report was filed." I happen to work for Lexis-Nexis, but I don't speak for the company. I work in a very different part of the company, and don't know the people involved with P-Trak.
