The model number of the original PlayStation in North America is SCPH-1001.
SCPH-1001 identifies the launch version of Sony’s original PlayStation sold in North America. The four-letter prefix, SCPH, appears across PlayStation hardware model numbers, while the digits distinguish regional versions, revisions, and later redesigns.
The regional numbering is the key to this question. Japan’s launch model was SCPH-1000, while the North American model was SCPH-1001. Early European versions were commonly identified as SCPH-1002. These consoles shared the same basic fifth-generation hardware design but differed in regional software and video standards.
Later North American revisions included models such as SCPH-5001 and SCPH-9001, which is why those numbers can look plausible in a quiz. The original PlayStation was later redesigned as the smaller PS one, introduced in 2000. Even though the PS one retained compatibility with the original library, it was a different model line from the launch SCPH-1001 hardware.
