This is accurate, except theworknumber is an equifax product. Experian and transunion have similar products however that share past comp data in exchange for a fee and/or current data sharing. Basically, "theworknumber" lets employers see what you made previously in exchange for the employer sharing what they pay all/most employees currently.

Large companies often share a lot of details too, such as yearly raises, bonuses, weekly rates, etc. Still, it is often inaccurate. For example, I have worked freelance extensively under my name (DBA) and llc and none of it is there.

You can pull your record if you want. If your employer uses workday, they almost certainly share every paystub with theworknumber.

You can freeze your data: https://employees.theworknumber.com/employee-data-freeze

HOWEVER, if you do so, many companies won't proceed with an offer until you unfreeze.
