An Alt Code is a keyboard shortcut that allows Windows users to enter special characters and symbols without searching through menus. By holding the Alt key and entering a specific number on the numeric keypad, you can insert characters that may not appear directly on your keyboard.

These shortcuts are useful for typing symbols, accented letters, mathematical characters, and currency signs in compatible Windows applications.

How to Use an Alt Code

Using an Alt Code is simple when your keyboard has a numeric keypad.

1. 
   

   Place the cursor where you want the symbol.

   
   


2. 
   

   Hold down the Alt key.

   
   


3. 
   

   Enter the required number using the numeric keypad.

   
   


4.

Why Use Alt Code Shortcuts?

An Alt Code can save time when you frequently use characters that are not available on your physical keyboard.

For example, writers may need copyright symbols, editors may use special punctuation, and professionals may regularly type currency or mathematical symbols. Instead of opening a character map every time, a keyboard shortcut can insert the required character quickly.

Alt Codes for Accented Letters

Alt codes can also help users type accented letters in certain Windows environments.

Examples include:

• 
  

  Alt + 0225 = á

  
  


• 
  

  Alt + 0233 = é

  
  


• 
  

  Alt + 0237 = í

  
  


• 
  

  Alt + 0243 = ó

  
  


• 
  

  Alt + 0250 = ú

  
  


• 
  

  Alt + 0252 = ü

  
  


• 
  

  Alt + 0241 = ñ

  
  

These can be useful when writing names, foreign words, or multilingual content.

What If Alt Codes Do Not Work?

If an Alt Code does not work, check whether you are using the numeric keypad. Traditional Alt-code entry generally requires the dedicated number pad rather than the number row above the letters.

Also check whether Num Lock is enabled. On laptops, the numeric keypad may require a function key or an embedded number-pad mode.

Some applications may also handle character input differently.

Alt Code vs Unicode

An Alt Code is not the only way to insert special characters. Unicode provides a broader character system used across modern computing.

In applications such as Microsoft Word, you can often enter a Unicode hexadecimal value and use a keyboard command to convert it into the corresponding character.

For example, typing 00B0 in Word and pressing Alt + X converts it into °.
