According to Square's publicity department, the original Famicom release sold 800,000 copies. As of March 31, 2003, the game, including all re-releases at the time, had shipped 1.28 million copies worldwide, with 1.08 million of those copies being shipped in Japan and 200,000 abroad. Despite having only been released in June of that year, as of September 2007 the PlayStation Portable version had shipped 90,000 copies in Japan and 70,000 in North America. Despite these high sales, the game had sold the fewest copies of any of the first ten main games in the "Final Fantasy" series.
