I don't know why these people giving senstive information to ledger if you can able to buy on local distributor or trusted seller near in your area.
If you dont know check the list of distributor here https://www.ledger.com/reseller

And actually when I buy a product online I can use any name I want if the distributor or reseller is selling online you can use different name or give a different address like what o_e_l_e_o said.
Or you can buy to someone p2p just make sure check the device if its authentic follow the guide here below.
