International Reply Coupons, commonly known as IRCs, serve as a traditional method for amateur radio operators to prepay return postage for QSL cards from foreign correspondents. This system addresses the logistical challenge of sending local currency or stamps to another country, ensuring that a recipient can reply without incurring their own postal costs. IRCs are standardized vouchers that can be exchanged for the minimum postage of an unregistered airmail letter to a foreign country, providing a reliable mechanism for international correspondence in amateur radio.

Resources in this category provide essential information regarding the acquisition and redemption of these coupons. Operators can find details on which countries participate in the IRC scheme, lists of postal administrations that sell and accept them, and frequently asked questions about their usage. These resources are crucial for understanding the operational guidelines set by the Universal Postal Union (UPU), which governs the international exchange of IRCs, thereby facilitating efficient and courteous QSLing practices across borders.
