title: Difference between representation of MNCs?
body: <p>I was looking <a href="http://www.mcc-mnc.com/" rel="nofollow">mcc-mnc</a> list. during that I found different kind of representation of MNCs such as 01, 001 like.</p>
  
  <p>I was searching whether they are same or not, and found in  <a href="https://en.wikipedia.org/wiki/Mobile_country_code" rel="nofollow">Wikipedia</a> that MNC of 001 is not the same as MNC of 01. I understand this is a code. but still not able to understand how they can be different? if we treat them as numeric number then both are same.
   here are some of question which I have:</p>
  
  <ul>
  <li>What is the significance of forward zeros in MNCs number?</li>
  <li>Why they can not be treated as same MNCs?</li>
  <li>Is it just because we want to make them 3 digit or some other logic?</li>
  <li>If just we want to make them 3 digit can they be treated as same MNCs</li>
  </ul>
  
  <p>Any help to understand MNCs will be appreciated? </p>
