Election recount can occur if the margin of results for a constituency are within a 2% range (or scores between 49% and 51%). Unlike the previous elections, the recount is now triggered automatically rather than being called out manually from the candidates or counting agents, which was previously seen in 1991 (Nee Soon Central SMC), 2011 (both Presidential and Potong Pasir SMC) and 2015 (Aljunied GRC); additionally, a standby counting machine would be used for recount instead of being manually counted. Similar to past elections, overseas votes is disregarded during a recount of votes as it does not cause any impact from the eventual results, unless if the total overseas electorate is greater than the difference of votes.[39][40]
