How to Type ℕ on Mac, Chromebook, and Linux

On a Mac, open Character Viewer with Control+Command+Space, search for “Natural Numbers Symbol”, and insert it. Chromebook users can copy the symbol or use the Unicode input method where supported. On Linux, press Ctrl+Shift+U, type 2115, and press Enter.

Examples and Correct Usage

Some conventions include zero in ℕ and others begin with one, so define the intended set when ambiguity matters.

Use the actual Unicode character rather than a visually similar keyboard substitute when the distinction matters in mathematics, science, accessibility, searching, or data processing.
