Find your device’s serial number
Practical steps, with clear limits on what a registry can do.
Look on the device
Check the manufacturer label or system information. Use the serial rather than a model number, asset tag, operating-system key or accessory identifier.
Compare records
Match the number with original packaging, receipts or manufacturer account records. Keep identifiers and purchase evidence privately.
Choose the correct scope
Manufacturers can reuse similar serial formats. Select the correct brand and device category when searching or reporting.
