Get the UUID of a VM

Linux Windows

This document shows you how to get the universally unique identifier (UUID) of a virtual machine (VM) instance by using a tool that is specific to the VM's operating system.

Each VM has a UUID that has the following properties:

It is unique among Compute Engine VMs.
It is generated from the VM's project ID, zone, and name.
It is stable for the lifetime of the VM. If the VM is deleted and recreated in the same project, zone, and with the same name, the VM receives the same UUID.

UUIDs are only available for VMs created on or after October 30, 2014. If you have a VM created before that date, recreate the VM so Compute Engine can assign it a UUID.

Use operating system tools to get the UUID of a VM

To get the UUID of a VM, run the command that corresponds to the VM's operating system:

Linux

From the Linux VM, run the following dmidecode command:
```
sudo dmidecode -t system | grep UUID
```

Verify a response similar to the following:

UUID: 3748eb17-a207-5bc3-aa4f-3113a1b9409d

Windows (Cmd.exe)

From the Command Prompt on the Windows VM, run the following wmic command:
```
wmic path win32_computersystemproduct get uuid
```

Verify a response similar to the following:

UUID
81CBB42C-73A0-9660-6C7D-2FE94627F3A3

Windows (PowerShell)

From PowerShell, run the following Windows Management Instrumentation (WMI) command:
```
(Get-WmiObject -Class Win32_ComputerSystemProduct).UUID
```
Verify a response similar to the following:
```
81CBB42C-73A0-9660-6C7D-2FE94627F3A3
```
