This Month in Rochester History

Fifty years ago this month, citizens of Rochester were learning a new number - right along with everyone else in the United States. In June 1963 the United States Postal Service began to roll out its new Zone Improvement Program, which sorted mail by five-digit numbers popularly known as zip codes.  Rochester residents were assigned the zip code 48063.

The challenge for the postal service was to encourage public cooperation with the new plan.  A cartoon character named Mr. Zip showed up in advertising media to cajole postal customers into learning and using their new zip codes.  There was even a zip code song - click this link if you'd like to hear it.

In the late 1980s, population shifts in southeastern lower Michigan necessitated a revised zip code map, and the Rochester area received new zip codes of 48306, 48307 and 48309, while our old zip code of 48063 was reassigned to Columbus Township in St. Clair County.
