An apparatus for provisioning embedded Internet of Things Universal IDs (IoT UIDs) in Brownfield devices. The apparatus includes a display circuit, a requestor circuit, a request provisioning circuit, an IoT UID processing circuit, and an IoT UID provisioning circuit. The display circuit generates a graphical user interface (GUI) configured to receive one or more user input command values corresponding to device property data for one or more Brownfield devices. The requestor circuit generates a registration request that includes the device property data. The request provisioning circuit transmits the registration request to an IoT device registrar server. The IoT UID processing circuit interprets one or more IoT UIDs generated by the IoT device registrar server in response to the registration request. The IoT UID provisioning circuit at least one of: transmits the one or more IoT UIDs, or displays the one or more IoT UIDs on an electronic display.
