Allocation rules

From GTIN Allocation Rules Feb 2007:

A separate unique GTIN is required whenever any of the pre-defined characteristics of an item are different in any way that is relevant to the trading process. The guiding principle is if the customer is expected to distinguish a new trade item from an old trade item and purchase accordingly, a new GTIN should be assigned.

Albums

It is common among some companies e.g. EMI, SONY to use the "2" as CD identifier and the "4" as tape identifier in the last position before the check digit. Other companies, e.g. Fresh Sound Records with their El Bandoneon series do not use that scheme.
