Definition

What Is the Service Mark Entity?

Service Mark (℠) is the Letterlike Symbols character at Unicode U+2120 (SERVICE MARK). It marks a name or logo as a service mark for services — not goods.

Remember

Character     ℠
Unicode       U+2120
Hex entity    &#x2120;
Decimal       &#8480;
Named entity  (none)
CSS escape    \2120
Not the same  &trade; (™) · &reg; (®)

Hex, decimal, CSS, and a typed character all produce the same glyph: ℠. Prefer ℠ when you want an explicit entity. For goods trademarks use ™; for registered marks use ®.

Reference

Hex + Decimal + CSS

Three ways to produce ℠ in a single document (no named entity).

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Service Mark (℠)</title>
  <style>
    #point::after {
      content: "\2120";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x2120;</p>
  <p>Using HTML Code: &#8480;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Branding: CloudSync&#x2120;</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+2120 → ℠ in HTML. The browser turns it into ℠.

2. Decimal: same code point as 8480 → ℠. Same result as hex.

3. Named: HTML5 does not define a named entity for this character — use hex or decimal instead.

4. CSS: use \2120 in content (not an HTML entity). #point::after appends that ℠ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Service Mark.

Look-alikes

℠ ≠ ™ ≠ ®

U+2120 is service mark. ™ is trademark. ® is registered — pick the mark that matches your legal meaning.

Named

No `&…;` name

Do not invent a name. Use ℠ or ℠.

Legal

Glyph ≠ legal advice

Displaying ℠ does not create rights. Use it only when it matches how you identify your service mark.

Fonts

Glyph coverage

Some fonts omit U+2120. Test branding typefaces, or fall back to a superscript SM if needed.

CSS vs HTML

Do not mix escapes

\2120 belongs in CSS. ℠ / ℠ belong in HTML.

Semicolon

End references

Always finish with ; — write ℠, not &#x2120.

Service Mark (U+2120) and its entity forms (℠, ℠, CSS \\2120) are supported in all modern browsers. Glyph coverage depends on the font.
