I figured you were trolling but gave you the benefit of the doubt right up until you mentioned “all credit reporting agencies”, in Belgium. There are no credit bureaus in Belgium, only a central bank which (unlike US credit bureaus) is public sector and not interested in grabbing data for profit, or in obtaining any data it’s not legally required to obtain. Nice try though.

But FYI, your assumption would be wrong even in the US as well. Request your credit report from whichever credit bureau you believe is buying location data from your mobile phone provider. Notice the location data is not on that report. Then go to your local small claims court and spend ~$100 to open a lawsuit against them for $1k (+~100 in court costs). Bring to court proof that they bought your realtime CDMA/GSM location data, a copy of your credit report showing it’s not there, and a copy of the federal law requiring that credit report to be complete. It might be the easiest $1k you’ve earned. You don’t have to prove actual damages either because the statute specifies $1k per violation. If you can catch all three credit bureaus doing what you claim, that’s an easy $3k. Good luck!
