Courier companies need to understand that the United States can be divided into West America, East America, and America China according to geographical location. This is because the distance between things in the United States is long and the delivery fees are different.
In fact, zip codes can also be used to distinguish the geographical location of the United States. There are 50 states in the United States, which can be divided into ten major regions from 0 to 9 by zip code.
Generally speaking, continents with zip codes starting with 8 and 9 belong to the Americas West, which is close to the Pacific Ocean and has two of the largest ports in the United States, Los Angeles and Long Beach. In FBA shipping, the ship docks here, because the distance is relatively close, so the first freight will be cheaper.
States with zip codes starting with 4, 5, 6, and 7 belong to the United States and China. The largest city in the United States and China is Chicago. Because it is far from the United States, the shipping price will be higher.
States with zip codes starting with 0, 1, 2, and 3 belong to the eastern United States, and the eastern region is farther away than other regions, so the transportation time is also the longest, and the natural price is also the highest. Big cities like New York, Washington, Boston are all in this area.
