A unique identifier may be any of the following:
If you're checking against an electrical item, you should seek the serial number. This is a unique number typically found around the sides or base of the item. If it is accessible check inside the battery compartment. Alternatively, inspect the packaging or documentation that came with the item when it was purchased.

If you're checking against a handset, you should seek the IMEI number. This is a unique identifier for the handset that will display on the screen by dialing the following *#06#. Alternatively, it can normally be found on the documentation or packaging that came with the handset. Some handsets may also have a unique serial number. Please note you can add up to three identifers when performing a search on CheckMEND.
