Zip along with Mr. Zip
You would probably figure it out just by looking at it, but we’ll put any remaining uncertainty to rest. Yes, this is a card that was delivered to every home in the United States in 1967, only four years after the government decided to adopt ZIP Codes. Because ZIP is an acronym for “Zone Improvement Plan,” it’s written in capital.

The ZIP Code mascot is Mr. Zip, a friendly gentleman with bug eyes. Isn’t it curious to learn that something we take for granted was once so completely unknown that you needed a mascot to describe it to you?
