Abstract: There is a lot of speculation around the legitimacy of the results of the General Elections in Brazil with the use of electronic ballot boxes. There are fake news circulating all over the internet where suspicions are raised about the ballot boxes and the results. To evaluate the elections reliability, the public data of the Brazilian Presidential elections from 2002 to 2018 was observed, obtained in the Electoral Data Repository, made available by the Tribunal Superior Eleitoral. The Benford’s Law distribution is utilized for anomaly and fraud detection in numerical data, observing the frequency in which the digits 0 to 9 appear in the 1st, 2nd, 3rd, 4th digits of the observations. For electoral data, it is recommended to observe the pattern of the 2nd digits of the vote counts by city. It was used the Pearson’s Chi-Square test and G-test (likelihood-ratio) to evaluate if the distributions of the 2nd digits of the vote count for each candidate, by city, follow Benford’s Law – 2BL.
