+2 Q:

US ZIP Code in center between 2 ZIP codes?

How could I determine the closest 'center' ZIP code between two given US ZIP Codes?

+2 A:

map zip codes to latitude/longitude (google returned http://www.boutell.com/zipcodes/)
calculate geographical midpoint between the two coordinate pairs (e.g. http://www.geomidpoint.com/calculation.html)
look up the closest zip code for the resulting coordinate.
