Trivia: Introduced in 1963, what does the “ZIP” in ZIP code stand for?
Zone Improvement Plan
Zero Indicator Point
Zone Identification Post
Zulu India Papa
The correct answer is Zone Improvement Plan
So why is this answer correct? : Until 1963, the U.S. did not have standardized ZIP codes for addresses. To ease mailing issues, the U.S. Postal Service introduced “Zone Improvement Plan Codes.” The first number represents a broad region (for example, “9” is the West Coast and “0” is the Northeast), and the next two indicate smaller areas within that region. The final two numbers can represent streets, buildings, or specific businesses. For example, the ZIP code 12345 belongs to General Electric in Schenectady, New York.
