Zip+4 Querying
I have been assigned to undertake a new project by some friends of mine.
Basically, it's a very popularily used function. (LJ uses it.)
What I need to be able to do, is to auto-assign a Zip+4 according to city/state.
The only issue I'm having is, what about multiple zipcodes in a given city?
Rio Rancho (where I live) has two, and the form doesn't have a drop box. It's simply going to auto-insert the zip values into two text boxes.
Zip Code: (5 - in the first box) + (4 - in the next).
I don't want code, I just want a push in a suggested direction.
Is there a database somewhere with all this data publically accessible?
Should I build my own database to pull the values from and then cron the public DB and update as necessary?
Thanks.
