Our support agents may ask you for the serial number (also referred to as the MAC ID) of your Withings product. This 12-character number allows them to retrieve diagnostics and usage data for your product.

The serial number of your device starts with '0024' or 'a4:7e' and contains numbers and letters throughout. Depending on where you find the serial number, it can look like '0024E4XXXXXX / a47eXXXXXXXX' or '00:24:E4:XX:XX:XX / a4:7e:XX:XX:XX:XX.' 

If your device is already installed, you can find the serial number in the Health Mate app by going to Devices, selecting your product, and then scrolling down to the About section.

If your device is not installed, please refer to the table below to know where to find the serial number label:
