Video transcript
ZIP codes in the USA follow a specific pattern: a 5-digit primary code, with an optional 4-digit extension (e.g., 12345-6789). The first digit represents a group of U.S. states, the next two digits pinpoint a central post office in that region, and the last two digits identify specific delivery areas. The extension (ZIP+4) further narrows down the location for more precise sorting and is useful for large organizations or specific addresses within a ZIP code area.
