About California Zip Codes

Since 1963, ZIP codes are a method of postal codes implemented by the United States Postal Service (USPS). The acronym ZIP stands for Zone Improvement Plan. It is suitably printed in capital letters and was selected to suggest that the mail goes more expeditiously, when the dispatchers are mentioning the code in the postal address. The fundamental arrangement is composed of five decimal numeric digits. An expanded ZIP+4 code, launched in the 1980s, contains the five digits of the ZIP code, a hyphen, and four additional numbers that point to a more accurate position than the usual ZIP code.

The expression ZIP code was initially listed as a service mark (a category of trademark) by the USPS, however its listing has since lost validity.
