- Motorola Cellphone Serial Numbering
- -----------------------------------
- The Mechanical Serial Number (MSN) [also called serial number, SN,
- or even S], may be either 10 or 11 characters in length. The first
- 3 characters constitute the Accounting Product Code (APC). Typically
- the APC is not of interest to the field, with a single exception: the
- Express 850 is easily distinguished from retail Step-up models by its
- APC of 572. The fourth character is the location of manufacture.
- The fifth character is the year of manufacture, and the sixth character
- is the month of manufacture. The next four characters constitute the
- actual serial number of that telephone. Finally, if there is no
- eleventh character, the warranty period is one year; if there is an
- eleventh character it stipulates a warranty period which may be
- determined from the chart below.
