質問: 追跡番号を入力しても結果が出ませんでした。何がいけなかったのでしょうか?
回答: although, you get a tracking number instantly when the package is being sent, it can take up to 48 hours for the tracking number to actually show up in the tracking system. just be patient and wait a few hours. if you still don’t get any results then, check for typos or contact the support of your courier.
