HTML Entity for Not Identical To (≢)
What You'll Learn
How to display the Not Identical To symbol (≢) in HTML using named, hexadecimal, decimal, and CSS escape methods. This operator states that two expressions are not identical (e.g. A ≢ B means A is not identical to B).
This character is U+2262 (NOT IDENTICAL TO) in the Mathematical Operators block (U+2200–U+22FF). Render it with the named entity ≢, ≢, ≢, or CSS escape \2262. Compare with Identical To (≡, ≡) and Not Equal To (≠, ≠).

<style>
#point::after{
content: "\2262";
}
</style>
</head>

🧠 How It Works
Named Entity
≢ is the HTML named entity for U+2262—the most readable choice when writing identity-relation markup.
Hexadecimal Code
≢ uses the Unicode hexadecimal value 2262 to display the not-identical symbol.
Decimal HTML Code
≢ uses the decimal Unicode value 8802 to display the same character.
CSS Entity
\2262 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce: ≢. Unicode U+2262 in Mathematical Operators (U+2200–U+22FF).
Use Cases
The ≢ symbol (≢) is commonly used in:
Expressing that two expressions are not identical in form or definition.
Formal proofs and definitions involving identity relations.
Textbooks, papers, and lecture notes published as HTML.
Courses covering formal methods and symbolic logic.
Interactive math modules with web-based notation.
Unicode charts and HTML entity documentation for math symbols.
💡 Best Practices
Do
- Use
≢for readable identity-relation markup - Distinguish ≢ from ≡ (identical) and ≠ (not equal)
- Pair ≢ with plain-language description on first use
- Use numeric references in generated or XML-first workflows
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ≢ (
≢) with ≠ (≠) - Confuse ≢ with ≡ (
≡, identical to) - Use padded Unicode notation like U+02262—the correct value is
U+2262 - Put CSS escape
\2262in HTML text nodes - Use
\02262in CSS—the correct escape is\2262
