The numbers appear after doing bibtex + pdflatex + pdflatex.

Using \bibliographystyle{abbrvnat}

a

% !TeX TS-program = pdflatex

\documentclass[final,5p,times,twocolumn]{elsarticle}    

\begin{filecontents}{mainrefs.bib}
    @article{einstein,
        author="Albert Einstein",
        title="{Zur Elektrodynamik bewegter Korper}",
        journal="Annalen der Physik",
        volume="322",
        number="10",
        pages="891--921",
        year="1905",
        DOI ="http://dx.doi.org/10.1002/andp.19053221004",
        keywords="physics"
    }
    
    @book{dirac,
        title={The Principles of Quantum Mechanics},
        author={Paul Adrien Maurice Dirac},
        isbn={9780198520115},
        series={International series of monographs on physics},
        year={1981},
        publisher={Clarendon Press},
        keywords = {physics}
    }
\end{filecontents}

\usepackage{kantlipsum}

\journal{Nuclear Physics B}

\begin{document}

\begin{frontmatter}

\title{}

\author{}

\begin{abstract}
Let us suppose that the noumena have nothing to do
with necessity, since knowledge of the Categories is a posteriori.
\end{abstract}

\begin{keyword}
Space \sep  Time
\end{keyword}

\end{frontmatter}

\section{Introduction}

The history starts with \cite{einstein} and continues with   \cite{dirac}.
 
\kant[1-3]

\bibliographystyle{abbrvnat}

%\bibliographystyle{elsarticle-num}% ordered numbers <<<<<<

\bibliography{mainrefs}

\end{document}

Or use instead \bibliographystyle{elsarticle-num} for ordered numbers.

  • @KRISHNA CHAUHAN Did you try the code from my answer and compile the file several times after running bibtex? bibtex.exe filename.tex must be run from the command prompt or usually from the tex editor.
