>>8851016>Why is the United States defined as a new postage rate zone (Zone 4)?Because the delivery charges of the United States will increase much more than those of other countries. Therefore, we will separate the postage rates for items to the U.S. from the current Zone 2 and define Zone 4 as a new postage rate zone. In addition, the U.S.'s external territories such as Guam and Saipan will have the same delivery charges so these territories will be integrated into Zone 4.
