An international reply coupon (IRC) is a voucher that can be exchanged for the postage required to send a letter or small packet from one country to another. When someone sends a letter to a recipient in another country and includes an IRC, the recipient can exchange the IRC for the necessary postage to reply to the sender. This allows for the sender to pre-pay for the return postage, making it easier for international correspondence. The recipient can then take the IRC to their local post office and exchange it for the appropriate postage to send their reply. **
