ZIP CODE ANNIVERSARY….Yesterday was the 40th anniversary of the ZIP Code, and the LA Times blurb about this reported the following postal fact:
In 1963, the Post Office Department delivered 68 billion pieces of mail to 188 million customers at fewer than 60 million addresses. Today, the U.S. Postal Service delivers 203 billion pieces to 291 million Americans at more than 141 million addresses.
So the population of the U.S. has increased 55% over this period but the number of addresses has increased 135%. That seems like a pretty big difference, doesn’t it?
