Hello - We are using your mapquest geocoding API for our software. We enter the zip code to find a city/state/country. We are seeing incorrect results when entering USA zip codes. They are returning results for cities in South America, Europe etc. One example is 05672. Stowe, Vermont, USA. It is returning results for Sao Paolo Brazil. This is just one example. It is happening to many US based postal codes.
Here is the URL as a test:
A refresh of that URL brings a different result on numerous occasions.
I noticed similar messages in other forum threads. Is it possible there are servers out of sync?
