In the United States, the Office of Price Administration (OPA) was responsible for implementing the rationing program. Different types of goods had different coupon values, and the number of coupons required for a particular item could change throughout the war. For example, in 1942, one pound of butter required 10 red points, while one pound of sugar required 5 blue points.
The rationing system also included processing coupons, which were required for the purchase of certain processed foods. These coupons were issued in addition to the regular red, blue, and green coupons.
The rationing program in the United States officially ended on June 22, 1945, when most wartime price and rationing controls were lifted. However, some items, such as sugar, continued to be rationed for a few more months.
