'''Code page 437''' ('''[[CCSID]] 437''') is the [[character set]] of the original [[IBM PC]] (personal computer).<ref>{{cite web|title=CCSID 437 information document|archive-url=https://web.archive.org/web/20160327100212/http://www-01.ibm.com/software/globalization/ccsid/ccsid437.html|archive-date=2016-03-27|url=http://www-01.ibm.com/software/globalization/ccsid/ccsid437.html}}</ref> It is also known as '''CP437''', '''OEM-US''', '''OEM 437''',<ref name="GGDC"/> '''PC-8''',<ref name="PCMAG"/> or '''MS-DOS Latin US'''.<ref name="DIS"/> The set includes all printable [[ASCII]] characters as well as some accented letters ([[diacritic]]s), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "'''OEM font'''" or "'''high ASCII'''", or as "[[extended ASCII]]"<ref name="PCMAG"/> (one of many mutually incompatible ASCII extensions).

This character set remains the primary set in the core of any [[Enhanced Graphics Adapter|EGA]] and [[Video Graphics Array|VGA]]-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set.{{NoteTag|Systems available in Eastern European, Arabic, and Asian countries often use a different set; however, these sets are designed to match 437 as much as possible. The designation "OEM", for "original equipment manufacturer", indicates that the set could be changed by the manufacturer to meet different markets.}} Many file formats developed at the time of the IBM PC are based on code page 437 as well.
