Number Sign Flat

The number-sign-flat icon represents a modern, flat design version of a number or symbol, often used to indicate a hashtag or a numeric key. It originates from the concept of typographic symbols and has been adapted for digital use. The icon is significant in the context of communication and information organization.

In software applications, the number-sign-flat icon appears in text editors like Microsoft Word Online, Google Docs, and Dropbox Paper, as well as in social media platforms like Twitter, Instagram, and Facebook. It is often used to represent a hashtag or a reference.

From a UX perspective, the number-sign-flat icon communicates the idea of categorization or tagging in a clean and simple interface. It helps users understand that they can interact with the icon to access related information, making it a crucial element in user interface design.

Number Sign Flat is one of 1,000 icons in Flex color icons, made by Streamline and released under CC BY 4.0. It is drawn on a 14 × 14 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds NumberSignFlatIcon to components/icons/streamline-flex-color-number-sign-flat.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed NumberSignFlatIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Number Sign Flat icon, or any of 1,000 Flex color icons icons, and install it from a prompt.
