Label/Label Code
"The Label Code (LC) was introduced in 1977 by the IFPI (International Federation of Phonogram and Videogram Industries) in order to unmistakably identify the different record labels (see Introduction, Record labels) for rights purposes. The Label Code consists historically of 4 figures, presently being extended to 5 figures, preceded by LC and a dash (e.g. LC-0193 = Electrola; LC-0233 = His Masters Voice). Note that the number of countries using the LC is limited, and that the code given on the item is not always accurate." http://www.iasa-web.org/icat/08_0.htm
It should not be confused with the CatalogNumber. A catalog number identifies a particular album, whereas a label code identifies an entire Label.
ClutchEr2 reports that very recent CDs do not have a CatalogNumber. Instead they use the BarCode without the trailing zero and 13th check digit number.
