How Do I Get The Hashtag Symbol On My Keyboard?

Press Shift + 3 on a US keyboard or Option + 3 on a UK keyboard to type #

What's happening with this symbol?

The hashtag symbol (#) shares the number 3 key on most keyboards and only appears when you press Shift (or Option on UK Mac keyboards)

That secondary character setup goes way back to early typewriters, where symbols like #, $, and % were tucked into the corner of number keys. The # symbol didn't really take off until the 2010s, when Twitter and Instagram turned it into a tagging tool. On international keyboards, you might find it on a dedicated key or through different combinations, but the core idea stays the same across layouts.

Here's exactly how to type it

Use Shift + 3 (US) or Option + 3 (UK Mac) to type the hashtag symbol immediately

Pick the instructions that match your setup:

  1. US QWERTY Keyboard (Windows or Mac)
    • Find the key with both 3 and #—usually the third key from the left in the top number row.
    • Hold down the Shift key.
    • Press the 3/# key once.
    • Let go of both keys to insert the # symbol.
  2. UK QWERTY Keyboard (Windows)
    • Hold the Shift key.
    • Press the key labeled with both 3 and #.
    • Release both keys to type the symbol.
  3. UK QWERTY Keyboard (Mac)
    • Hold the Option (⌥) key.
    • Press the 3 key.
    • Let go of both keys to insert #.
  4. Other ways in word processors
    • Microsoft Word 365 (version 2503 or later, as of 2026): Go to Insert → Symbol → More Symbols → Special Characters → Hash Sign (#) → Insert.
    • Google Docs: Go to Insert → Special Characters, type “number sign” in the search box, then click the # symbol from the results.
    • LibreOffice Writer 7.6+: Go to Insert → Special Character, search for “hash”, and select #.

Still not working? Let's fix it

Check your keyboard layout settings and Num Lock status if Shift + 3 doesn’t produce #

Try these steps if the hashtag won't show up:

  • Double-check your keyboard layout settings:
    • Windows 12: Head to Settings → Time & Language → Language & Region → Keyboard → Add a keyboard. Pick “English (United States)” or “English (United Kingdom)” as needed Microsoft Support.
    • macOS Sequoia (15.x): Open System Settings → Keyboard → Text Input → Edit → Add Keyboard → British or ABC – Extended. Make sure the layout matches your actual keyboard.
  • Turn on Num Lock on full-size keyboards:

    If you're using the numeric keypad on a full-size keyboard, hit the Num Lock key to activate it. When Num Lock is off, the keypad might not register Shift + 3 correctly.

  • Try your system's symbol picker:
    Operating System Shortcut
    Windows Press Windows + . (period) to open the emoji & symbols panel. Switch to the Symbols tab and scroll to find #.
    macOS Press Control + Command + Space to open the Character Viewer. Type “number sign” in the search box and double-click #.

Keep this from happening again

Keep your keyboard layout updated and clean to avoid future hashtag symbol issues

Follow these simple habits to prevent keyboard symbol headaches:

  • Update your operating system regularly. Microsoft and Apple push out quarterly updates that improve keyboard layout detection and accessibility features, which helps prevent symbol mismatches Microsoft Support.
  • Match your keyboard to your system layout. Plugging a US layout keyboard into a UK system (or the other way around) will give you £ instead of # when pressing Shift + 3. Use matching layouts for both keyboard and OS to avoid this mess.
  • Clean your keyboard regularly. Dust and grime can jam keys or mess with key presses. Use a can of compressed air to blow out debris between the keys, and wipe the surface with a slightly damp microfiber cloth. Skip harsh cleaners that might strip the key coating.
