The postal service started the use of postal zones for large cities in 1943. By the early 1960s a more general system was needed. On July 1, 1963, ZIP codes were created for the whole country but they were not mandatory. In 1967, these were made mandatory for many types of mail. The system was soon used for all mail.
The zip code can be formed by using letters and/or numbers; it all depends on the standard chosen by the country. In the US, the zip codes, also know as ZIP Code 5 or Zip Code 5 plus 4 are usefull to organize the mail delivery process. Germany was the first into use the system, followed by the US, in the 60's.
