A unique alphanumeric identifier assigned to each Android device by its manufacturer allows for its distinct identification. This string of characters serves as a digital fingerprint, differentiating it from all other devices. For example, a specific phone model might have a product code, but the serial number distinguishes one specific instance of that model from another identical one.
Its significance lies in its use for warranty claims, device authentication, and tracking. Manufacturers and service providers utilize it to verify the authenticity of a device, check its warranty status, and manage service requests. Historically, these identifiers have been etched onto physical components. Now, they are stored electronically within the device’s firmware.
