ASCII Code

ASCII stands for American Standard Code for Information Interchange. It was created in 1963 by the American Standards Association (ASA), which later evolved into ANSI (American National Standards Institute).

How to Type ASCII Characters on Your Keyboard

WINDOWS PCs with Numeric Keypad (Numpad)

  1. Hold down the Alt key on the left side of your keyboard and do not release it.
  2. While holding Alt, type the ASCII number on the numeric keypad (e.g. 64 for @, 164 for ñ, 92 for \).
  3. Release the Alt key: the character appears immediately on screen!

LAPTOPS Laptops without dedicated Numpad

Use the Fn + NumLock shortcut to activate the numeric overlay printed on letter keys (usually M, J, K, L, U, I, O, 7, 8, 9). Alternatively, in Windows 10/11 press Win + . to open the native symbols selector or run charmap.

MAC & LINUX On macOS & Linux

On macOS, use the Option key combinations (e.g. Option + n then n for ñ, Option + 2 for @) or press Cmd + Ctrl + Space for the Character Viewer. On Linux, press Ctrl + Shift + U, type the hexadecimal code (e.g. 40 for @), and hit Enter.
