Appendix of Inactivated Codes
Find out which codes are no longer in use
Below is a cumulative list of all codes that have been inactivated. These codes should not be applied to any new titles.
It is highly recommended that inactivated codes which have already been assigned to titles be replaced. To this end, instructions on code replacement are included below. Since it may not be possible or practical to locate and replace all occurrences of inactivated code, note that BISG will never re-assign inactivated codes to another literal.
This list is sorted by inactivated code. LVCWA is in bold for codes last active in the 2022 Edition (that is, inactivated when creating the 2023 Edition).
IC = Inactivated Code. LVCWA = Last Version Code Was Active.
