Happy anniversary to Mr. Zip!

Smithsonian National Postal Museum

50 years ago today, the Zoning Improvement Plan went into effect. This was not the first time Post Office Department used a system of postal zoning. According to the Smithsonian National Postal Museum Web site, a system of postal zoning was implemented in 1943., due to the increase of mail sent in the midst of World War II.

Mr. Zip was created to convince a reluctant public to add 5-digits to the end of addresses when sending a letter.

I went to the Quincy Post Office this morning expecting to see something celebrating the 50th Anniversary of the ZIP Code. I saw no streamers, no banners, and no cake. I asked Barb behind the counter for me free piece of cake. She didn't know that today was a special day in the history of mail delivery.
