title: SQL - Numeric data type with leading zeros
body: <p>I need to store <a href="http://www.acep.org/content.aspx?id=30464" rel="nofollow">Medicare APC codes.</a>  I believe the format requires 4 numbers.  Leading zeros are relevant.  Is there any way to store this data type with verification?  How should I store this data (varchar(4), int)?</p>
