The April 20 launch of the third-generation iPad will be in South Korea, Brunei, Croatia, Cyprus, Dominican Republic, El Salvador, Guatemala, Malaysia, Panama, St Maarten, Uruguay and Venezuela.
By April 27, the new tablet will be available in Colombia, Estonia, India, Israel, Latvia, Lithuania, Montenegro, South Africa and Thailand.
Apple launched the device last month and sold three million over the course of its first weekend on the market.
China has been noticeably absent from an iPad release schedule, and some analysts said it may be the result of a nettlesome trademark battle with Chinese computer firm Proview Technology.
Debt-laden Proview is suing Apple in China for trademark violation for calling its tablet computer "iPad."
