PSPsid

PSPsid is a term used to describe a unique identifier associated with a Sony PlayStation Portable (PSP) device. In official and third‑party documentation it is described as a persistent device identifier that enables software and services to recognize a specific PSP unit across sessions and applications.

The PSPsid is intended to be stable throughout the device’s lifetime, surviving power cycles and software updates. It is typically embedded in the system’s non‑volatile memory and is not normally visible to end users. Developers reference the PSPsid when implementing features that require device binding.

Usually the PSPsid is not user‑configurable. It is assigned by the system at manufacturing or first boot and remains tied to the hardware until a factory reset or device repurchase. In games and services supporting cloud saves or licenses, the PSPsid helps ensure data stays with the correct device.

Security and privacy concerns arise because the PSPsid is a hardware‑bound identifier. Services should minimize exposure of the value and implement appropriate privacy protections, giving users control over data sharing and ensuring that the identifier is not exploited for tracking beyond legitimate purposes.

PSPsid is distinct from user account identifiers such as a PSN ID and is separate from network addresses or cryptographic keys used for secure communications. It is one example of a platform device ID used to bind content and features to a specific PSP unit.
