Number Sign Alt Code and Symbol

The Alt code for Number Sign is 35. Hold Alt, type 35 on the numeric keypad, then release Alt. Number Sign also has the Unicode codepoint U+0023, so you can type it with Alt+35 on Windows, search for U+0023 in macOS's Character Viewer, use # in HTML, or \0023 in CSS. If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly — the Alt key method requires a physical numpad.
