I recently obtained my credit score information from Schufa. I chose the free option ("Datenkopie"). The oldest entry is this one (blanked out by me):
I don't remember ever having done business with that company. That's not to say I didn't, I just don't remember. But I'm sure I don't have an active contract with them. So I should be able to get that one deleted.
But is there actually any advantage to getting it deleted? I have very few entries (in chronological order: that one, two by two different banks (1 each), one because of my credit card contract, and one because I once asked for a different credit card (but that one got declined)). So given that there will only be 4 entries left and one of them definitely is negative, should I leave that one in there?
