Postcard is a kind of card mail with communication properties. There are many kinds of postcards, which can be divided into postcards printed and distributed by postal departments (postage postcards, postage-free postcards and free postcards) according to the nature of printing and distribution; Postcards printed by non-postal units can be divided into two categories. In foreign countries, most postcards printed by postal departments are printed with postal currency cards. Postcards printed by publishing houses, museums and industrial and commercial enterprises can only be printed.

According to the regulations of the Ministry of Posts and Telecommunications of the People's Republic of China, postage postcards are uniformly printed and distributed by the Ministry of Posts and Telecommunications, and no other unit may print them. Postcards printed by local postal departments can be printed with "China People's Post Postcards" (now "China Post Postcards"). Postcards printed by publishing houses and other non-postal departments are only allowed to print the words "Postcards" and are not allowed to use the words "Postcards of China People's Post".
