Republic of Viet-Nam Miltary Postal Service KBC Numbers and Unit Information Click here to view the KBC list (requires Adobe Acrobat Reader) KBC (Khu Buu Chinh) numbers, or military postal distribution codes (representing postal zones) were used to route mail to troops while obscuring units and locations from the enemy, similar to those used by American APOs (Army Post Offices). Each Republic of Viet-Nam military unit was assigned a four-digit KBC number. Some KBCs remained in one location while others moved with the troops. To date, no official records have surfaced listing all KBC numbers, dates of operation, locations and units served, as this information was apparently destroyed after the fall of Saigon on April 30, 1975. Many Republic of Viet-Nam military documents, mail, uniforms, certificates, and awards were likewise destroyed by soldiers and their families trying to avoid being placed in a re-education or concentration camp. Commissioned officers and members elite units such as the Rangers, Marines or Airborne units were especially at risk for persecution. Many of those who fled the country had their documents confiscated upon arrival in another country. Fortunately, enough documents survive to enable study of the Republic of Viet-Nam military postal system. A list of KBC numbers is being assembled from surviving military covers, ID cards and other documents.
