50 YEARS OF ZIP CODE
It was back in 1963. A historic and tumultuous year for those living in USA:
President John F. Kennedy was assassinated, Rev. Martin Luther King Jr. delivered “I Have a Dream” speech and the ZIP code was first introduced.
USPS was founded in 1775 and postal carriers had to rely on hand sorting based on local addresses. Correspondence went through 10 postal workers before it arrived as your local mail. By the 1940s, the Post Office realized its sorting system was not serving the country properly.
