Windows ALT code specification

Version 2.0.0 · Last reviewed 2026-07-28

Definition
Windows ALT codes insert a character by holding Alt and typing a numeric code on the keypad. Without a leading zero the code uses DOS/CP437; with a leading zero it uses Windows-1252.
What it calculates
The keypad sequence (Alt+n or Alt+0nnn), Unicode code point, and HTML entity for each byte in CP437 and Windows-1252.
Inputs
  • Character glyph, name, or Alt code (e.g. Alt+0169)
  • Code set: DOS/CP437 or Windows-1252
  • Optional category filter (accents, currency, math, …)
Outputs
  • Keystroke to type on Windows
  • Character glyph for copy/paste
  • Unicode code point and HTML entity
Formula
Alt+n → CP437[n]; Alt+0nnn → Windows-1252[nnn]

Use the tool above to browse DOS/CP437 (Alt+n) and Windows-1252 (Alt+0nnn) characters.

How to type ALT code symbols

  1. Enable Num Lock
  2. Hold Alt
  3. Type the digits on the numeric keypad (not the top row)
  4. Release Alt — the character appears

Examples: Alt+65 → A. Alt+3 → ♥. Alt+0169 → ©.

Codes with and without leading zeros

Style Example Character set
Alt + n (no leading zero) Alt+169 Legacy DOS code page 437
Alt + 0nnn (leading zero) Alt+0169 Windows code page 1252

Both forms use the same byte range 0–255, but glyphs often differ—switch Code set in the tool to compare.

Method Steps
On-Screen Keyboard Start → “On-Screen Keyboard” → Options → turn on numeric keypad → click digits while holding Alt
Fn + NumLk Enables a hidden numpad on many laptop letter keys
Windows + Period Opens the emoji and symbol picker (Windows 10/11)

Frequently asked questions

Key distinctions behind the tool.

Why does my ALT code not work?

Turn Num Lock on, use the numeric keypad (not the top-row number keys), type every digit while holding Alt, then release Alt. On many laptops you need Fn+NumLk or the On-Screen Keyboard.

What is the difference between Alt+3 and Alt+0169?

Codes without a leading zero use the legacy DOS code page 437 (for example Alt+3 → ♥). Codes with a leading zero use Windows-1252 (for example Alt+0169 → ©). The same number can mean different characters in each set.

Do ALT codes work on Mac or Linux?

Classic Alt+number entry is Windows-specific. On Mac use Option combinations or Character Viewer. On Linux use Compose keys or Unicode entry (Ctrl+Shift+U).

What is the ALT code for the degree symbol?

Alt+0176 produces ° in the Windows-1252 set. In the DOS set, Alt+248 is also the degree sign.

How do I type ALT codes without a numeric keypad?

Use Windows On-Screen Keyboard with the numpad enabled, a laptop Fn+NumLk overlay, Win+. emoji picker, or Character Map (charmap).
