Ally Darling (Anna Faris) is een vreemde jonge vrouw die het magische aantal van twintig verschillende vriendjes heeft bereikt. Ze besluit om al haar ex-vriendjes opnieuw te bezoeken, in de hoop dat een van hen de ware liefde is. Ze krijgt hierbij hulp van haar buurman, de rokkenjager Colin (Chris Evans).
Nee, helaas is What's Your Number? nog niet beschikbaar op Netflix in Nederland.
