U+2255

The symbol ≕ is called “equals colon” (Unicode U+2255). It’s a compact notation mark used when you need a specific equality-related glyph. Below you’ll find meaning, practical uses, and ready-to-copy variants.

Equals Colon Symbol Meaning

≕ (equals colon, Unicode U+2255) is a mathematical punctuation-like symbol that represents an equality relationship paired with a colon-style distinction. In written math and technical notation, it’s used to convey a specific variant of “equals” that differs from the plain equals sign (=). Because typographic and semantic meanings can depend on the surrounding context (for example, a chosen notation system in a textbook or typeset document), it’s best to use ≕ when you specifically need this glyph rather than substituting a standard equals sign. When publishing or coding, copying the Unicode character ensures consistent rendering across tools that support it.

Common uses

  • Indicating a specialized equality relation in math notes or worksheets
  • Labeling definitions or equivalence steps in technical documents
  • Marking equality-with-condition in markup or equation templates
  • Using in formatted lists or comparisons where a distinct symbol is preferred
  • Typography for equations in design mockups and educational materials
