Hello,
I’m not sure how current your zip code database is, but my zip code (23114) is not found and I’ve lived in this house over two years.
What is the problem you’re having?
23114 is not in your database, it returns a no results found message. My question was how often do you refresh your resources so that this zip code, in use at least two years now, would return a result?
Our zip code to latitude/longitude data came from the 2000 U. S. Census. Unfortunately it is not due to be updated until 2010.
We are looking for an alternative source but all we have found are ones that have to be licensed that we don’t know the provenance of. (It would be annoying to license a zip-code-to-latitude-longitude database and find out it’s the same one we already have.)
