imeisv

IMEISV, or IMEI Software Version, is a designation used to identify not only a mobile device but also the software version running on that device. It extends the International Mobile Equipment Identity (IMEI) by including a two-digit software version (SV) value, providing a more complete reference for device management, diagnostics, and support.

The IMEI itself is a 15-digit number that uniquely identifies a mobile device on networks. The IMEISV adds one or two SV digits (commonly shown together with the IMEI, for example as imei-sv), allowing manufacturers and operators to distinguish between hardware units that share the same IMEI but run different software versions. The SV value typically ranges from 00 to 99 and reflects the firmware or software build that was active at production or during a particular update.

In practical use, IMEISV helps manufacturers, service centers, and network operators track compatibility for updates, service eligibility, and technical diagnostics. It can aid in quality assurance, warranty validation, and fraud prevention by linking a device’s software version to its identity. However, IMEISV is not a universal indicator of operating system version or feature set, and its interpretation can vary by vendor and region. It is also considered sensitive device information, and sharing it can raise privacy concerns.

Overall, IMEISV complements the IMEI by providing a concise reference to the device’s software state, supporting device management workflows while requiring careful handling to protect user privacy. See also: IMEI, 3GPP specifications.
