Sometimes we need a hash symbol in a latex document. You need to use the \# command to print this symbol in a latex document.

\documentclass{article}
\begin{document}
   \# LaTeXhelp\\[6pt]
   \# hashtag\\[6pt]
   \# learning
\end{document}

Output :

Use hash symbol in latex.

There is another method by which you can print the hash symbol in a LaTeX document, which is by using the \char"0023 command. If the \# command doesn’t work, you can print the hash symbol to the document with the \char"0023 command.

\documentclass{article}
\begin{document}
  \verb|\char"0023| $\rightarrow $ \char"0023\\[6pt]
  \char"0023 latexhelp\\[6pt]
  $ V^{\char"0023}\Big|_n $
\end{document}

Output :

Use hash symbol in latex.
