A collection of facts is not and can not be copyrightable, especially when it was mechanically derived/collected (no human creativity). So, no, it is absolutely not "Equifax's IP".
Not on an individual basis. If you collected a large number of them and someone copied them from you, then you could have a database right claim, which is sort of similar to copyright, but much less powerful. https://en.wikipedia.org/wiki/Database_right
