Conference	Method
ACM conferences (e.g., CHI, KDD, WebConf, CIKM that use the acmart LaTeX style)	Use \settopmatter{printfolios=true} right after \documentclass. \documentclass[sigconf, screen]{acmart} \settopmatter{printfolios=true}
ACL conferences (e.g., ACL, NAACL, EACL, EMNLP)	Comment out \pagestyle{empty} in the conference style file (e.g., acl2023.sty) \ifacl@finalcopy % \thispagestyle{empty} % \pagestyle{empty} \pagenumbering{arabic} \else \pagenumbering{arabic} \fi
IEEE VIS (or TVCG and some other IEEE conferences)	Use the preprint option for the vgtc LaTeX style file. \documentclass[preprint]{vgtc}
NeurIPS	Use the preprint or the final option for the neurips LaTeX style file. \usepackage[preprint]{neurips_2022} \usepackage[final]{neurips_2022}
