 * :kconfig:option:`CONFIG_NRF_CLOUD_CLIENT_ID_SRC_IMEI` - If you enable this option, the ID is automatically generated using a prefix and the modem's IMEI (``<prefix><IMEI>``).
+  This is the default.
   You can configure the prefix by using :kconfig:option:`CONFIG_NRF_CLOUD_CLIENT_ID_PREFIX`.
   The default format of the prefix is ``nrf-`` and it is valid only for Nordic devices such as Thingy:91 or an nRF91 Series DK.
   For custom hardware, use a prefix other than ``nrf-`` by modifying :kconfig:option:`CONFIG_NRF_CLOUD_CLIENT_ID_PREFIX`.
