A Unicode character is assigned a unique ''Name'' (na).<ref name="Chapter4"/> The name is composed of uppercase letters A–Z, digits 0–9, [[hyphen-minus]] and [[spaceSpace (characterpunctuation)|space|space]]. Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed. The name is guaranteed to be unique within Unicode, and can be used to identify a code point and its character. Ideographic characters, of which there are tens of thousands, are named in the pattern "{{Smallcaps|{{lc:CJK UNIFIED IDEOGRAPH}}}}-''hhhh''". For example, {{unichar|4E00}}. Formatting characters also have names: {{unichar|00A0}}.

The following Unicode categories do not have a Name value assigned: Controls (General Category: Cc), Private use (Co), Surrogate (Cs), Non-characters (Cn) and Reserved (Cn). They may be referenced, informally, by a generic or specific meta-name, called "Code Point Labels": {{not a typo|<control>, <control-0088>, <reserved>, <noncharacter-''hhhh''>, <private-use-''hhhh''>, or <surrogate>}}. Since these labels contain "<" and ">", they can never appear in a Name, which prevents confusion.
