March's cars generally followed a simple designation scheme in which the first two digits correspond to the year (69–91), and the third digit or letter corresponds to the formula. Some peculiarities emerged, which are documented below. There were some minor exceptions to these rules, for example xx5 designated both some very early Formula B/Atlantic cars, some early F5000s and some early 2-litre sports cars.

* '''[[Formula One]]''' – 701-781, 811-821, 871-881. Subsequent March F1 cars took the CG prefix after Cesare Gariboldi, a Leyton House March team manager who was killed in a road accident in 1989:<ref name=smith>{{cite journal|last1=Smith|first1=Damien|title=Hand of the Creator|journal=[[Road & Track]]|date=February–March 2013|volume=64|issue=6|pages=64–69}}</ref> CG891, CG901, CG911. Note that, during 1972, three distinct F1 cars appeared: 721, 721X (low-polar-moment) and 721G (F2-based). At the start of the 1987 season, the team ran the 87P/87B, a hybrid F1/F3000 car.
* '''[[Formula Two]]''' – 702-842. Japanese F2 cars in 1985-86 were designated 85J and 86J. A 772P appeared in 1977 based on an old Atlantic chassis as a prototype for the 782.
