What & Why

What is a ZIP Code?

A ZIP Code is a five-digit (or nine-digit with ZIP+4) numerical code that identifies a specific geographic area within the United States. These codes are used by the USPS to sort and route mail quickly and accurately. The term 'ZIP' is an acronym for Zone Improvement Plan.

The Structure of ZIP Codes

A standard ZIP Code consists of five digits. Here’s a breakdown of what each digit represents:

• First Digit: Represents a broad geographic area of the United States, ranging from 0 in the Northeast to 9 in the West.
• Second and Third Digits: Together, these digits designate a specific region or metropolitan area within the group of states identified by the first digit.
• Fourth and Fifth Digits: These digits indicate a specific post office, delivery zone, or street within the region.

ZIP+4 codes add four digits to the basic five-digit ZIP Code, separated by a hyphen. These additional digits provide even more precise location information, such as a specific building, floor, or department within an organization. The ZIP+4 code helps the USPS further automate mail sorting, reducing the chances of misdelivery.
