Nearctic: 1) Canada, 2) Mexico (north), 3) USA; Neotropical: 1) Mexico (south) ( Keirans et al. 1996 a, Guzmán-Cornejo & Robbins 2010, Lindquist et al. 2016, Guglielmone et al. 2021).

Several records of Ixodes scapularis have been published under the name Ixodes dammini , a synonym of Ixodes scapularis ( Camicas et al. 1998, Keirans & Robbins 1999), but Ixodes dammini is still treated as valid in Kassiri & Nasirian (2021) and Nasirian & Zahirnia (2021), among others.

Records of Ixodes scapularis from the Neotropical portion of Mexico are treated as provisionally valid in Guglielmone et al. (2021).
