title: How can I quickly determine the State for a given zipcode?
body: <p>I don't need the city or address, just the state. And I don't want to make an API call if possible. The priority is a light-weight solution, ideally just Javascript.</p>
  
  <p>I have a user-input <code>zipcode</code>, and I want to display a paragraph of text depending on the state that the zipcode is in. I know it's much more complicated to lookup City <em>and</em> State, and for that an API such as the one the USPS exposes is probably best. But to just match state, perhaps on just the first three numbers, the solution (I think) should be easy and lightweight. </p>
  
  <p>Javascript ideally. PHP could also work.</p>
