Most Motorola products follow the same serial number conventions. As such, this often enables you to determine the approximate manufacture date for a device.
The serial number convention follows the following general format:
123ABC4567
Where 123 is an unique three digit code for each model series, where BC determines manufacture year and month respectively, and where 4567 is a unique four digit serial number for the device in question.
To determine the manufacture year and month, refer to the table below:
