ZIP codes are simply five digits. The starting digit (0-9) identifies a
broad region of the country. The beginning 3-digit sequence identifies a
major processing center. A full 5-digit ZIP code can encompass a few
blocks or hundreds of square kilometers, depending on the density of
addresses (population). ZIPs ending in 98 or 99 are often reserved for
the Post Office itself.
Fascinating, huh? ;-}
