In 1963, the United States Postal Service added a new number to addresses across the United States to help make sorting and mail delivery faster. What was it called?
Answer ZIP Code
ZIP codes greatly changed the way mail was delivered. They made mail delivery faster and more efficient. Now ZIP codes are also used for legislative districts, school zoning, and statistics. Their name stands for Zone Improvement Plan Codes.
