What are ZIP Codes?
The United States Post Office created the ZIP code system in 1963 to help the postal service track the delivery of mail. The system was originally only used for tracking the delivery of mail, but it has now been adapted to help people with addresses keep track of their shipments as well. The ZIP code system has now become an important part of everyday life in the United States. Most people in the United States have a ZIP code, even if they have never used it for anything.
The term ZIP is an acronym for Zone Improvement Plan. It was chosen to suggest that the mail travels more efficiently and quickly (zipping along) when senders use the code in the postal address.
