What is the structure of a Southco part number?

All Southco part numbers begin with a 2-character Product Class, which identifies the product category. The Product Class is always followed by a dash. There can be up to 16 characters (including dashes) after the Product Class, and can contain numbers, letters or a combination of both. Examples: <ul style="list-style-type: square;"> <li>Letters and Number: 4C-PH-M3-1B0-K000</li> <li>Numbers only: 64-10-113-50</li> </ul>
