FAQ: Product Update and Change Notifications

Change notifications come in two forms: PCN and PUN. PCN stands for Product Change Notification. PUN stands for Product Update Notification.

Official Definitions

Product Change Notification (PCN) – Change to existing product form, fit or function, and is deemed significant enough for customer notification.

Product Update Notification (PUN) – Changes to product that do not affect fit, form or function but the company has been determined the customer should get an update for.

Crystalfontz PCN and PUNs are issued via email or RSS to let customers know that something on the part will be changing, and how we are addressing that change.
