Happy 50th Birthday ZIP Codes!
Have you ever wondered how your ancestors received their mail across the USA before the 1963 five (5) digit Zoning Improvement Plan (ZIP) code? Of course 124 larger cities were assigned 1 to 2 digit zoning codes as early as 1943, during WWII. But now, the 5 digit zip code is instrumental to every day life. The Census Bureau even uses ZIP codes to analyze demographic data.
Happy 50th anniversary to the ZIP code - July 1963!
