Romain Grosjean is the latest driver to reveal his choice of permanent race number ahead of the 2014 season.
The Frenchman took to Facebook to reveal that his preferred number is 8 - his race number in 2013 - with 29 and 11 his back-up selections.
Though nobody else has, as yet, opted for 29, Grosjean's third choice (11) is the preferred number for Sergio Perez.
Last month, in the wake of the FIA's announcement that from this season drivers will be able to select permanent race numbers for the duration of their F1 careers, Fernando Alonso revealed that his preferred option is 14.
"It's always brought me luck, ever since I won at the age of 14, on 14th July in 1996, with a kart that had the number 14," he said. "Let's see it if still brings me luck."
Nico Rosberg is hoping to use 6, while the first choices of other drivers include 19 (Massa), 25 (Vergne) and 77 (Bottas).
