I registered and asked for my "Employment Data Report".
Besides showing all my pay data for the past two years (pay period start, pay period end, pay date, hours, and pay for each pay period) as I expected, it also lists everyone who has "procured your data" in the past 24 months.
The inquiries were interesting. Four organizations inquired. One is entirely as I expected, one is expected but the timing is slightly odd, one is maybe expected except they made a lot more inquiries than I would have expected, and one I have no idea what the heck they are doing.
The entirely expected one is my bank. Last year I applied for a home equity line of credit and there is one inquire near the start of that, and one that looks like it was just before they approved the loan.
The expected but odd one is Capital One. I applied for a new credit card from them. The oddity is the inquiry was about a week after I had received and started using the new card. I'd have expected it to be before they approved the application.
The one that is maybe expected except for the number of inquiries is Credit Karma. There are 8 inquiries, about a month apart, from January 2020 through September 2020. The report only goes back to January 2020 so it seems likely they were also inquiring before that. So once a month up until around the time Intuit bought Credit Karma.
The one I have no idea at all about is from the Centers for Medicare and Medicaid Services dba CMS. That's a federal government agency that runs Medicare and works with the states to run Medicaid. I'm not old enough for Medicare and not poor enough for Medicaid and have not applied for any services CMS deals with as far as I know. The inquiry was in October 2020, and I don't recall doing anything unusual related to health at all around then.
