The service mark symbol (), the letters SM in superscript style, is a symbol used in the United States and some other jurisdictions to provide notice that the preceding mark is a service mark. This symbol may be used for service marks not yet registered with the relevant national authority. Upon successful registration, registered services are marked with the same symbol used for registered trademarks, the registered trademark symbol ®. The proper manner to display the symbol is immediately following the mark in superscript style.

Keyboard entry[edit]

The character is mapped in Unicode as U+2120 SERVICE MARK (HTML ℠).[1] Unlike the similar trademark symbol, there is no simple way to type the service mark symbol on Microsoft Windows, but the built-in charmap application can help. In Microsoft Outlook or Word, type 2120 and Alt-X. On Macintosh systems, the symbol can be inserted by using the Character Palette. On Linux systems, it can be inserted by pressing Compose, then s, and finally m.
