With the release of [[PC DOS]] version 3.3 (and the near identical [[MS-DOS]] 3.3) IBM introduced the code page numbering system to regular PC users, as the code page numbers (and the phrase "code page") were used in new commands to allow the character encoding used by all parts of the OS to be set in a systematic way.<ref name="Duncan_1988_MS-DOS_Encyclopedia"/>
[[File:IBM CJK Code Page Numbers.svg|right|thumb|IBM code page numbers (CPGIDs and CCSIDs) used for CJK encodings. Microsoft's use of code page numbers for CJK encodings differs, and is noted in brackets where applicable.]]
After IBM and Microsoft ceased to cooperate in the 1990s, the two companies have maintained the list of assigned code page numbers independently from each other, resulting in some conflicting assignments. At least one third-party vendor ([[Oracle Corporation|Oracle]]) also has its own different list of numeric assignments.<ref name="oracle.com"/> IBM's current assignments are listed in their [[CCSID]] repository, while Microsoft's assignments are documented within the [[MSDN]].<ref name="Microsoft_Codepage-ID"/> Additionally, a list of the names and approximate IANA ([[Internet Assigned Numbers Authority]]) abbreviations for the installed code pages on any given Windows machine can be found in the Registry on that machine (this information is used by Microsoft programs such as [[Internet Explorer]]).
