Codes are assigned to manufacturers and publishers, not brands or product lines, in part because these can be bought, sold, and licensed between manufacturers. A code for a brand or product line does not help retailers or distributors to identify the source of an item or product.
Codes can be assigned to brands/product lines when they are separate entities from the parent company (distributors make checks and orders out to the separate entity and not to the parent company). Codes are meant to identify the manufacturer, not the brand.
Magazines and books are considered a product of the Publisher and therefore are not assigned codes. The code is assigned to the publisher.
A registration fee of $25.00 USD will be charged at checkout. Codes are valid for 10 years, after which they may be renewed. It is strongly recommended that you register your SMC using a permanent general email address for your company rather than one for an individual employee.
