International Reply Coupons

From Stamps of the World

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

The different types of IRC are shown here >> IRC TYPES & FLAWS

The IRC was introduced in 1906 at a Universal Postal Union congress in Rome. At the time an IRC could be exchanged for a single-rate, ordinary postage stamp for surface delivery to a foreign country, as this was before the introduction of airmail services. An IRC is exchangeable in a UPU member country for the minimum postage of a priority or unregistered airmail letter to a foreign country.

The current IRC, which features the theme "Water for Life," designed by Czech artist and graphic designer Michal Sindelar, was issued in 2013 and is valid until 31 December 2017. A new design by Vietnamese artist Nguyen Du for 2017-2021 was adopted in Istanbul in 2016.

IRCs are ordered from the UPU headquarters in Bern, Switzerland by postal authorities. They are generally available at large post offices; in the U.S., they are requisitioned along with regular domestic stamps by any post office that has sufficient demand for them. A British 1 Shilling IRC issued in 1959.

Prices for IRCs vary by country. In the United States in November 2012, the purchase price was $2.20 USD; however, the US Postal Service discontinued sales of IRCs on 27 January 2013 due to declining demand. Britain's Royal Mail also stopped selling IRCs on 18 February 2012, citing minimal sales and claiming that the average post office sold less than one IRC per year. IRCs purchased in foreign countries may be used in the United States toward the purchase of postage stamps and embossed stamped envelopes at the current one-ounce First Class International rate ($1.05 USD as of April 2012) per coupon.

IRCs are often used by amateur radio operators sending QSL cards to each other; it has traditionally been considered good practice and common courtesy to include an IRC when writing to a foreign operator and expecting a reply by mail. If the operator's home country does not sell IRCs, then a foreign IRC may be used.

Previous editions of the IRC, the "Beijing" model[clarification needed] and all subsequent versions, bear an expiration date. Consequently, a new IRC will be issued every three years.

In 1920, Charles Ponzi made use of the idea that profit could be made by taking advantage of the differing postal rates in different countries to buy IRCs cheaply in one country and exchange them for stamps of a higher value in another country. This subsequently became the fraudulent Ponzi scheme.In practice, the overhead on buying and selling large numbers of the very low-value IRCs precluded any profitability.

The selling price and exchange value in stamps in each country have been adjusted to some extent to remove some of the potential for profit, but ongoing fluctuations in currency value and exchange rates make it impossible to achieve this completely, as long as stamps represent a specific currency value, instead of acting as vouchers granting specific postal services, devoid of currency nomination.
