Doesn't a mapping company (mapquest, google map, yahoo map, etc.) or the

We will have two zipcodes and the road mileage distance between those

two postal centers.

I assume by "road mileage" you mean actual mileage if driven, and you're
not missing the obvious option of computing the distance between the
zips based on lat/long.

Also, I doubt you know all the mileages between each zip (hence dist
isn't required), but do you even know a high percentage? Why not only
store records where you know the distance? Might make the file much
smaller.
