Definition

What Is the Not Identical To Entity?

Not identical to (≢) is the Mathematical Operators character at Unicode U+2262 (NOT IDENTICAL TO). It states that two expressions are not identical under ≡ — for example A ≢ B.

Remember

Character     ≢
Unicode       U+2262
Named entity  &nequiv;  (also &NotCongruent;)
Hex entity    &#x2262;
Decimal       &#8802;
CSS escape    \2262
Affirmative   &equiv; (≡, U+2261)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ≢. Prefer &nequiv; in HTML source for clarity.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`&nequiv;`	HTML markup (also `&NotCongruent;`)
Hex entity	`≢`	HTML markup
Decimal entity	`≢`	HTML markup
CSS escape	`\2262`	Stylesheet `content`
Direct character	`≢`	UTF-8 HTML text

When to Use Which

Situation	Use
Readable HTML source	`&nequiv;`
Numeric entity required	`≢` or `≢`
Generated text via `::before` / `::after`	`content: "\2262"`
Identical to ≡	`&equiv;` — see Identical To
Not equal ≠	`≠`

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Not Identical To (&nequiv;)</title>
  <style>
    #point::after {
      content: "\2262";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &nequiv;</p>
  <p>Using Hex Code: &#x2262;</p>
  <p>Using HTML Code: &#8802;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Example: A &nequiv; B</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: &nequiv; (or &NotCongruent;) is the clearest HTML form and renders ≢.

2. Hex: U+2262 → ≢ in HTML. Same result as the named entity.

3. Decimal: same code point as 8802 → ≢. Same result as hex.

4. CSS: use \2262 in content (not an HTML entity). #point::after appends that ≢ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with the not-identical-to entity.

Pair

`&nequiv;` ≠ `&equiv;`

&nequiv; is the negation. &equiv; is the affirmative identical to (≡).

Look-alikes

Not `≠` or `&NotCupCap;`

≠ is ≠ (not equal). &NotCupCap; is ≭ (not equivalent under ≍). Identity and equivalence are different relations.

Aliases

`&nequiv;` = `&NotCongruent;`

Both map to U+2262. Prefer the short &nequiv; in everyday HTML.

CSS vs HTML

Do not mix escapes

\2262 belongs in CSS. &nequiv; / ≢ / ≢ belong in HTML.

Encoding

Declare UTF-8

If you paste ≢ directly, keep <meta charset="UTF-8"> so the file is not misread.

Semicolon

End references

Always finish with ; — write &nequiv;, not &nequiv.

Compatibility

Browser Support

Not identical to (U+2262) and its entity forms (&nequiv;, ≢, ≢, CSS \\2262) are supported in all modern browsers. Glyph availability depends on the font.

✓ Universal encoding

Not Identical To (&nequiv;)

Encode with named, hex, decimal, or CSS escape — or paste ≢ directly in UTF-8 HTML.

Bottom line: Prefer &nequiv; for readable HTML. Use \\2262 only inside CSS content.

Remember

Key Takeaways

Unicode: this character is U+2262 (decimal 8802).
HTML: prefer &nequiv; (alias &NotCongruent;) — or use ≢ / ≢.
CSS: use \2262 inside content for generated text.
Watch out: &nequiv; ≠ &equiv; ≠ ≠.

One line: U+2262 → &nequiv; / ≢ / ≢ / CSS \2262.

Frequently Asked Questions

How do I display not identical to (≢) in HTML using entities?

Use &nequiv; (named), ≢ (hex), ≢ (decimal), type ≢ in UTF-8, or the CSS escape \2262 in content. All render ≢. Prefer &nequiv; in HTML source.

What is the Unicode value for nequiv?

U+2262 (NOT IDENTICAL TO). Hex 2262, decimal 8802. It belongs to the Mathematical Operators block (U+2200–U+22FF).

Is there a named HTML entity for U+2262?

Yes. HTML5 defines &nequiv; and &NotCongruent; (aliases for the same character). Related: &equiv; for ≡ (U+2261).

When should I use this HTML entity?

Use it when two expressions are not identical or not congruent under ≡ (e.g. A ≢ B). Prefer &nequiv; for readable source. For ordinary inequality use ≠ (≠).

What is the difference between HTML code and CSS entity for U+2262?

HTML entities (&nequiv;, ≢, or ≢) go in markup. The CSS escape \2262 is used in stylesheets (usually in the content property of ::before/::after). Both render ≢.

How is ≢ different from ≠ or ≡?

≡ (U+2261, &equiv;) means identical to. ≠ (U+2260, ≠) means not equal. ≢ (&nequiv;) specifically means not identical — do not substitute one for another.

Did you know?

Not identical to (≢) is Unicode U+2262 (decimal 8802) — NOT IDENTICAL TO in Mathematical Operators. HTML5 provides &nequiv; and &NotCongruent; (same glyph). It negates identical to (&equiv;, ≡, U+2261). Related: ≠ (≠, not equal).
