Los Angeles is one of the important centers of industry and commerce, international trade, science and education, entertainment and sports in the United States, and also one of the main bases of petrochemical, marine, aerospace and electronic industries in the United States. According to the rules, the 1, 2, and 3 digits of the postal code indicate the distribution area or processing distribution center, and the 4 th and 5 th digits indicate the post office or distribution area.

Later, in order to deliver the parcel to the actual address more quickly and accurately, the last four digits were added to the five-digit postal code in the United States, but the main first five digits were filled in correctly, which would not affect the delivery. The last four digits are cells or parts that are accurate to the address. So it can also be said that the total number of zip codes in the United States is 9 digits.
