Be able to address letters and postcards correctly, check the postage, send them from a post office or postbox, and use the right method for cash, important items and mail going abroad.
Explanation
On a letter or postcard, write the recipient's postal code (7 digits), address and name, and also write your own address and name as the sender. The postage depends on size and weight. If you are not sure, you can ask the post office counter to weigh it. Once you put stamps on it, you can drop it in a postbox.
As a rule, ordinary letters and postcards are not delivered on Saturdays, Sundays or public holidays. If it is urgent, use express mail (速達). Always send cash by cash registered mail (現金書留). For important documents, registered mail (書留) is useful because a record is kept until delivery.
When sending mail abroad, some items cannot be sent to certain countries or regions, and perfume and spray cans cannot be sent to any country. When sending goods, you also need a shipping label listing the contents.
The postage for standard and non-standard mail is decided by size and weight. If you are not sure, have it weighed at the counter.
