The service mark ℠ has no Windows Alt code, so copy it or use Alt+X after typing 2120 in Word. It marks a brand used for services rather than physical goods. The distinction is mainly American, and ™ is accepted for both in most of the world.

04 Troubleshooting & confusables
| Looks like it | But it's actually | When to use |
|---|---|---|
| ™ (U+2122) | Trade mark sign, traditionally for goods | The safer default. It is understood everywhere and covers services in most jurisdictions. |
| SM as two letters | A plain-text fallback | Reasonable where the character is unavailable, since ℠ is missing from many fonts. |
| An empty box | A missing glyph in the current font | This character has poorer font coverage than ™. Test it before using it in print. |
05 FAQ
What is the Unicode code point for the service mark?
It is U+2120, decimal 8480. It has no Windows Alt code, because it is not in the Windows-1252 code page.
When should I use ℠ instead of ™?
When the mark identifies a service, such as consulting or a repair business, rather than a product. Outside the United States the distinction carries little weight and ™ is the usual choice.
Does ℠ mean anything is registered?
No. Like ™ it is an unregistered common-law claim. Registration is what allows the ® symbol.
Why does it show as a box on some devices?
Font coverage for U+2120 is much thinner than for ™. If the box appears, fall back to ™ or write SM in plain letters.
How do I type it in Word?
Type 2120 and press Alt+X, which converts the code point in place. On a Mac, open the Character Viewer and search for "service mark".
