Finished device selling?

I would like to sell my Financed Notebook. On the bill, however, is the financing number and my address and phone number. I have / want to give this but the seller because the notebook has a Saturn Plus warranty. Is this problematic in any way?

Why should that be problematic?
What do you have in mind?
Name and phone number are available at most in the phone book
And the financing number is uninteresting if the case has long been completed
