Device Identification
Use the Beats Product Identifier Guide to determine the device's Apple serial number. When entering a serial number to begin service, verify that the color, size, and model of the device matches the Apple serial number. All models have a unique configuration code (the last 3–4 characters of the serial number). This code identifies the color, size, and model of a Beats product. If there is a mismatch between the configuration code and the device’s color, size, or model, the device has been modified and is considered ineligible for service.
