title: How do I validate Credit Card and Bank Account numbers?
body: <p>I know there have been a lot of discussion related to this topic, e.g. <a href="https://stackoverflow.com/questions/2004532/credit-card-validation-can-card-name-contain-non-ascii-characters">Credit Card validation: can Card Name contain non-ASCII characters?</a></p>
  <p>The reason I wanted to ask this question is because people could find all the information at one place.</p>
  <p><strong>What I've found out</strong> (Please correct me if/where I'm wrong):</p>
  <blockquote>
  <p><em>Title - Length - Format</em></p>
  <p>Credit Card Number - MIN 13, MAX 19 - Numeric</p>
  <p>Credit Card Name - MAX 26 - Alpha Numeric (Cannot contain dots after Initials?)</p>
  <p>Bank Account Number (btw, I'm in India) - MIN 11, MAX 15 - Numeric</p>
  <p>Bank Account Name - Sorry, no idea - Alpha Numeric? (again, no idea)</p>
  </blockquote>
  <p>Please provide answers so that this will help people who have to juggle with financial data.</p>
