We need your help. I have a problem that I need to solve, and I have not found specific solutions for this. In ASP.NET MVC we want to implement a specific function.
This is for a student training course, we know that a student will conduct a training course outside and inside a specific city. The student will issue two or three postal codes that are friends, familly, etc.
I need to do to compare one zip code with a zip code list to find the closest.
The postal code list is where the student will take the course.
For this task it is obvious that I need an API or some kind of WebService. It is also obvious that this task will require high traffic if we can not transmit the list of postal code, and not one postal code.
We know that Google can do something, but it only accepts one postal code, which is not what we are looking for.
So, is there somewhere an API, method, or something else that allows you to compare one zip code with a list of zip codes to find the closest one? Any ideas?
Thank.
Edit No. 1: Please note that they need a way to transfer the list of postal code into one postal code. The list may be very large and may need to be compared with another list.
