In the csv format, a field value of 00123 (I don't > really know what zip code formats are) is perfectly valid. 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? ;-} Paul -- Paul M.
