title: Excel - Comparing values from 2 columns, to 2 other columns
body: <p>My question is giving me some trouble.  I am trying to compare an origin zip code and destination zip code, with another origin zip code and destination zip code.</p>
  
  <p>An example would be Origin: 63304, Destination: 56687</p>
  
  <p>I want to be able to find out if this origin and destination combination exists in a different list.</p>

  <p>In the image you can see that I have the first two origin and destination zip codes, then a space, then there are another combination of origin and destination zip codes.</p>
  
  <p>How can I compare columns L&amp;M with O&amp;P to see if that combination shows up anywhere in either list?</p>
