USA postal code example:

Since 1963, the United States Postal Service has used ZIP Codes as a postal code system.

The term ZIP, which stands for Zone Improvement Plan, was chosen to imply that when senders use the code in the postal address, the mail travels more efficiently and thus faster (zipping along).

The basic format is 5 digits long. An extended ZIP+4 code, introduced in 1983, consists of the ZIP Code’s five digits, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code.
