So, I haven't seen/found any code to determine which province a specific code would fall under, so I thought I'd add this here in the discussion page. This is just some JavaScript I hacked together for a project I'm working on, so it might not be the most effective way of accomplishing said goal. If you want to re-post this somewhere more appropriate (or use it or whatever), please feel free to do so.

	{
