title: What is the best column type for a United States ZIP code?
body: <p>I want to store <strong>Zip Code</strong> (within United States) in MySQL database. <strong>Saving</strong> space is a priority.  which is better option using VARCHAR - limited to maximum length of 6 digit or using INT or using MEDIUM Int . The Zip code will not be used for any calculation. The Zip code will be used to insert (Once), Updated (if required) and Retrieved - Once (but it can be more than once) .</p>
  
  <p>Which is better option to use here <strong>VARCHAR or INT or MEDIUM  IN MYSQL</strong> ? Please suggest anything else ?</p>
