International Business Reply Service (IRBS) Charge

IBRS is a service where a domestic addressee pays the postage and handling charge upon delivery of international mail so that the overseas sender does not have to pay the postage. This is a convenient service when sending questionnaires or purchase orders to a mail order business overseas. The service is available throughout the world.


The addressee must pay the postage and handling fees upon delivery of the mail or when receiving the mail at the post office (post-payment is also acceptable).
