What was the original PlayStation's official model number in Japan?

The original Japanese PlayStation had the official model number SCPH-1000.

Sony used SCPH-1000 for the first retail hardware revision released in Japan in December 1994. The SCPH prefix appeared on PlayStation hardware and accessories, while the number identified a particular model or revision.

Later versions received different designations, including SCPH-3000, SCPH-5000, and SCPH-7000. These revisions could change internal components, regional features, or manufacturing details without representing an entirely new generation of console.

Collectors sometimes confuse the launch model number with the PlayStation’s product name or with later regional models. SCPH-1000 specifically identifies the first Japanese retail hardware version, not every original PlayStation sold worldwide.
