DXers or anyone who uses International Reply Coupons (IRCs) should redeem the so-called “Nairobi” design IRCs that expire on December 31, 2013. The US Postal Service no longer sells IRCs, and most USPS employees are unfamiliar with them. The USPS’s International Mail Manual (IMM) covers the topic, however, in Section 381. If the postal clerk can’t help, ask for a supervisor. Also, take along a copy of the appropriate IMM section. If you do need IRCs, the new Czech design coupons do not expire until the end of 2017. — Thanks to The Daily DX
