Well, yes, but it may look strange to your seller. Some Saskatchewan rural addresses are pretty peculiar. Or you may have included the "ring" in your apartment address.
I recently had a buyer whose address suddenly moved from BC to the USA and back again. I checked the address, all was well, and she became a steady customer.
Or he may just want to be sure that you are a real human being.
In any case, I can't see any harm in communication.
