Alt+254 is a classic code from the CP437 table used by the original IBM PC, which is why there is no leading zero. This symbol does not exist on the Windows-1252 table, so the classic code is the only Alt code for it.
On a laptop without a numpad
Press Win+. to open the emoji panel, pick the Symbols tab and search for "black square". Or open Character Map from the Start menu. In Microsoft Word you can type 25A0 followed by Alt+X. Some laptops have a hidden numpad on the J, K, L, U, I and O keys that activates with Fn.
On a Mac
Alt codes do not exist on macOS and this symbol has no dedicated shortcut. Open the Character Viewer with Control+⌘+Space, search for "black square" and double-click it.
In HTML and code
Use ▪ in HTML, "\25A0" in CSS and "\u25A0" in JavaScript. See the Black Square Symbol guide for every platform.
