Hi, could this be adapted to accept an address instead of a zip code?
The SPD cart validator support address and Google autocomplete and doing the same for the custom validator will be a huge improvement.
What would be the cost of modifying as such?

First, congratulations for this amazing article and documentation.
really hard to see App's giving such a good support like this to others Devs
