Esteban Ocon will race with the number 31 when he makes his Formula 1 debut later this month following confirmation that he will replace Rio Haryanto at Manor for the remainder of the 2016 season.
The Renault reserve driver, who is also backed by Mercedes, will partner Pascal Wehrlein for the final nine races.
Although he has yet to confirm why he chose the number, which will be his throughout his F1 career, it's likely to do with his karting days as he raced under the number in 2007 when he won the championship.
The last time the number 31 was used was by David Brabham for Simtek in 1994.
