What is an International Reply Coupon? Cost??

Question

please help me

Answer 1

An international reply coupon (IRC) is a coupon that can be exchanged for one or more postage stamps representing the minimum postage for an unregistered priority airmail letter of up to twenty grams sent to another Universal Postal Union (UPU) member country. IRCs are accepted by all UPU member countries.

UPU member postal services are obliged to exchange an IRC for postage, but are not obliged to sell them.

The purpose of the IRC is to be able to send someone in another country a letter, along with the cost of postage for them to reply. If the addressee is within the same country, there is no need for an IRC because a self-addressed stamped envelope (SASE) will suffice; but if the addressee is in another country an IRC removes the necessity of acquiring foreign postage or sending appropriate currency.

Answer 2

They don't have those anymore in the U.S. - you used to be able to buy them at the post office and send them to someone overseas who would be able to use them to pay for postage back to you
