title: Wordpress location search by zip code
body: <p>I need to do the following in a client Wordpress based site.</p>
  
  <p>1- The user enters an us zip code
  2- List the stores near that zip code (no more than 50 miles away)</p>
  
  <p>I only have the zip codes of each store, no coordinates.</p>
  
  <p>Is it possible to do this using google maps or a similar service? I need to do this only with the zip codes, the other.</p>
  
  <p>Thanks!</p>
