As other posters have told you, the address is to a freight forwarder.
"But what are the numbers in the middle"
They are a special secret code that identifies to the Freight Forwarding Company the buyer and country to which the package has to be, well, forwarded. Like a type of account number. You don't really have to worry about those numbers.
By The Way: You will very likely see an additional charge on the sales records of this transaction. eBay charges an international fee of 1.65% of the total amount paid by your buyer IF the buyer's registered address is not in the US but the shipping address is. Like in Oregon. Or in Delaware.
Why Oregon? Same reason why so many freight forwarders are located in Delaware:
No State Sales Taxes.
