I have just received some items back that I posted to Canada. As a rule on all parcels I send I just put house number and postcode and country as my return address. The one to Canada was no different, however that came back to me because it had not been accepted by Canadian Customs - No full name. I was not warned by the PO so it has cost me another £11 for special delivery to send it again.
Just another reason why things may not get through.
