Dell has also since dropped the E from the Latitude line (due to switching to a USB C/Thunderbolt dock system, rather than the e-Port analog pin-system docks), and the models are delineated by number now, e.g.: Latitude 5480, 5570. The 3 series has replaced the 5 series as the budget line. The entry-level line was the 5 series, but as of 2015 the 5 series and 7 series Latitude laptops are the primary lines of Latitude laptops. The 15' 'Premium' line was the 8 series, until the E-series merged this line with the 6 series (Model numbers being along the lines of C8x0 or D8x0).

In the past, the high-end line was the 6 series, being the C6x0, D6x0, and E64x0 lines, but as of 2015 this line has been discontinued and replaced by both the 5 series and the 7 series.

The Latitudes from the early 1990s up until the C*00 lines weren't in a set 'series', instead of going under the models CP and XP with modifiers at the end, e.g.: XPi, CP M233. The Dell Latitude series have dropped the initial alphabet in newer model types (as in Latitude 7480 whose predecessor was E7470), and became the successor to the popular Latitude E, D, C, and X series.
