The serial number or Universally Unique Identifier (UUID) can be found in 3 places:

- [Packaging box of your Joan device](#Box)
- [Joan Configurator (Mobile app/Desktop app)](#Configurator)
- [MyJoan](#Portal)

## {#Box} Packaging box of your Joan Device

If you still have the packaging of your Joan device, you can find the serial number on it, just above the serial code.

It will be denoted as “SN” followed by a 32-character number.

## {#Configurator}Joan Configurator

## Joan Configurator mobile app:

1. Run the Joan Configurator mobile app
2. Under Joan, UUID should be displayed

    - If you have many devices, and you are not sure what UUID you need, click on the device in the Configurator and the display will brighten up.

## Joan Configurator desktop app:

You can also find the device’s serial number in the [Joan Configurator](/help/joan-devices/what-is-the-joan-configurator) as soon as you connect your device.

### {#Portal}MyJoan

 If you have already connected your device to [MyJoan](https://my.getjoan.com/), you can also find the serial number in the “**Settings**” -> “**Rooms**” -> “**Devices**” section. For a direct link to that page, see [the Devices page in MyJoan](https://my.getjoan.com/settings/rooms/devices).

Simply select a specific device to open the “**Edit device**” page and the number will be listed as “**UUID**” at the upper-right corner of the page.
