    How to get processor serial number (PSN)?

    chinmayhegde

      Is there a way to get CPU serial number(PSN) which is unique across all processors?.

       

      Tried below commands in Windows and Linux. Serial number is not coming up.

       

      Linux:-

      cpuid

       

      …….

      PSN: processor serial number           = false

       

      Windows:-

       

      wmic cpu get serialnumber

       

      [Returning empty output]

       

      Processor Type:-

      Intel Xeon processor E5-2600

      Intel Core i7 7th Gen

       

      Thanks,

      Chinmay

          Hello chinmayhegde
           
          Thank you for joining the community.
           
          In order to find the serial number (ATPO) of the processors you can refer to a QR code located at the edge of the processor and use a mobile app to scan the code, please refer to the following link for reference about where to find the ATPO:

          Hope this help.

            Years ago, privacy advocates had apoplectic fits - and even organized a boycott of the Pentium III processor - when Intel included serial numbers in their processors. Intel ended up completely removing the ability to programmatically read a serial number from the processor. Bottom line, you cannot read a serial number from the processor.

             

            Of course, administrators required a way to uniquely identify systems and support was included in the DMTF's SMBIOS specification (which all systems support) for programmatically obtaining board- and/or system-level serial numbers as well as a system-level UUID. You can programmatically obtain this information directly from the SMBIOS tables of your system or through the Windows WMI interface and/or the Linux DMI interface (DMI (or, more fully, DMIBIOS) was Intel's name for SMBIOS when it was first introduced; Linux has just been "a little slow" applying this name change).

             

            [Aside: Of course, what the DMTF did was identical to what Intel did, at least from a privacy standpoint, but while everyone took a fit when big, bad Intel did it in the processor, everyone quietly accepted it when the DMTF did it at the system level. Just saying.]

             

            Hope this helps,
