International reply coupons (IRCs) provide foreign addressees with a prepaid means of responding to inquiries, solicitations, or other types of communications that are initiated by U.S. senders. IRCs are exchangeable for postage stamps by postal administrations in member countries of the Universal Postal Union (UPU). Each IRC is equivalent in value to the destination country’s minimum postage price for an unregistered airmail letter. The purchase price is $2.10 per coupon.
As of October 11, 2007, only international reply coupons printed by the Universal Postal Union can be redeemed at U.S. Post Offices. The valid version of the international reply coupons printed by the Universal Postal Union is approximately 3.75 inches by 6 inches, has a barcode on the back, and has an expiration date of December 31, 2009. This policy is for international reply coupons issued by the United States as well as for those issued by foreign postal administrations.
