ASCII Codes — Full list of Characters, Letters, Symbols & Signs

ASCII is an abbreviation for the American Standard Code for Information Interchange. Approved by the American Standards Association (now known as ANSI for American National Standards Institute) in 1963, ASCII defined the standard for displaying characters on electronic devices.

Almost all computer systems today use the ASCII code to represent characters and texts. ASCII is often called US-ASCII. Now, ISO 646 is the internationally defined character sets standard.

ASCII started a 7-bit code, with 128 characters. The code consists of 33 non-printable and 95 printable characters. It includes letters, punctuation marks, numbers and control characters. It was later expanded by IBM to an 8-bit code and 256 characters.

Here’s the full list of ASCII characters, letters, symbols and signs, arranged in the order of character types.
