What Is a ZIP Code?
A ZIP code (Zone Improvement Plan code) is a 5-digit postal code used by the United States Postal Service (USPS) to sort and route mail. The system was introduced on July 1, 1963 to streamline the growing volume of American mail delivery.
The first digit of a ZIP code represents a broad geographic region of the country, from 0 in the Northeast to 9 in the West. Each subsequent digit narrows the delivery area down to a specific sectional center, post office, or delivery zone.
An extended ZIP+4 code (e.g., 90210-1234) adds four more digits to pinpoint a specific city block, building, or P.O. Box for precise mail delivery.
