My Benin mailing address will conform to this format:
Name, Peace Corps Volunteer
Corps de la Paix
Basically don't send me anything expensive, heavy, bulky, perisheable, breakable, or suspicous. Letters (air mail only) take about two weeks, packages at least four.
Here are the USPS guidlines for Benin-bound mail. Don't be put off by the special postage schedules--first class will always do.
