What is a Device ID?
A Device ID is a unique identifier assigned to a device by the manufacturer or the operating system. It is used to identify the device on a network, track its activities, and provide personalized experiences. Device IDs can be found in various forms, such as IMEI numbers for mobile phones, MAC addresses for computers, or UUIDs for tablets.
Device IDs are usually generated randomly and are not related to the device’s serial number. They are used by operating systems, apps, and websites to recognize the device and provide tailored services. For instance, a Device ID can be used to sync data across devices, enable push notifications, or track user behavior.
What is a Serial Number?
A Serial Number is a unique identifier assigned to a device by the manufacturer. It is usually printed on the device’s packaging, label, or engraved on the device itself. Serial Numbers are used to track the device’s production, warranty, and ownership. They are often used by manufacturers to identify the device’s model, production date, and other relevant information.
Serial Numbers are usually alphanumeric and are assigned sequentially by the manufacturer.
