Zip-code system marks 50th anniversary
This upcoming week marks the 50th anniversary of the United States Postal Zoning Improvement Plan, or ZIP code system.
The system went into effect on July 1, 1963.
Former Osceola Postmaster L.L. Hagie was quoted in the June 25, 1963, issue of "The Osceola Sentinel-Tribune" as saying “The ZIP code is literally the last word in efficient mail addressing.”
