Embodiments of the invention provide a method, system and computer program product for physical location tagging via image recognition of physical components in a data center. The method includes acquiring an image scan of a field of view of a camera at a known location in a data center and matching an image of a device in the image scan to a pre-stored image of a similar device to determine a device type of the device in the image scan. The method also includes transmitting a directive to a known device in inventory of the determined device type to activate a visual indicator disposed on an exterior portion of the known device. Finally, the method includes re-acquiring the image scan to detect an activated visual indicator on the device in the image scan and, in response, mapping the known location in the data center to the known device in inventory.
