PS Vita hardware sales have topped 1.2 million units globally, boosted by the system's Western launch earlier this month.
As of February 26, software sales also surpassed two million units at both retail and across the PlayStation Network.
The platform holder said that Vita sales "have exceeded expectations... firmly establishing PS Vita as the must-have portable entertainment device across the world".
Sony Computer Entertainment CEO Andrew House added: "PS Vita was designed to deliver the ultimate portable entertainment experience, and we couldn't be more thrilled with the reaction we're seeing from consumers and the pace at which PS Vita is selling.
"The market has responded and there is clear demand for a mobile device capable of providing a revolutionary combination of rich gaming and social connectivity within a real world context.
"To sustain momentum, we're working closely with 3rd party developers and publishers to ensure the best games and franchises possible will be available on PS Vita, and our software line up for the remainder of 2012 will have something for everyone across the globe."
Last week, Sony Computer Entertainment UK managing director Fergal Gara told CVG that the early consumer response to Vita had been "very encouraging". On Monday, Vita games took the top two spots on the UK all formats chart.
