Subject: How to Translate Motorola Serial numbers to Determine the Date of Manufacture

> 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 or 123ABC45678
> Where 123 is an unique three digit code for each model series, where 
> the significance of A is unknown, BC determines manufacture year and 
> month respectively, and where 4567 or 45678 is a unique four or five 
> digit serial number for the device in question.
> To determine the manufacture year and month, refer to the table below: 
> Second Letter is the year: 
> A 1976 or 2000
> B 1977 or 2001
> C 1978 or 2002
> D 1979 or 2003
> E 1980 or 2004
> F 1981 or 2005
> G 1982 or 2006
> H 1983 or 2007
> J 1984 or 2008
> K 1985 or 2009
> L 1986 or 2010
> M 1987 or 2011
> N 1988 or 2012 
> P 1989 or 2013 
> Q 1990 or 2014 
> R 1991 or 2015 
> S 1992 or 2016 
> T 1993 or 2017 
> U 1994 or 2018 
> V 1995 or 2019 
> W 1996 or 2020 
> X 1997 or 2021 
> Y 1998 or 2022 
> Z 1999 or 2023
> The third letter identifies the portion of the month in which the unit was made:
> A First half of January 
> B Last half of January 
> C First half of February 
> D Last half of February 
> E First half of March 
> F Last half of March 
> G First half of April 
> H Last half of April 
> J First half of May 
> K Last half of May 
> L First half of June 
> M Last half of June 
> N First half of July 
> P Last half of July 
> Q First half of August 
> R Last half of August 
> S First half of September 
> T Last half of September 
> U First half of October

The following information was obtained directly from Motorola and sent to Repeater-Builder for inclusion in this document.

Serial Number Format
Direct from Motorola Solutions

Motorola Solutions equipment serial numbers follow two standard formats.

First format: three digits, three letters, and four digits: The fifth character of the serial number represents the YEAR code and the sixth character represents the MONTH code. Example:

2 0 3 F L W 6 4 2 1

Decodes to 2010 (L), first half of November (W).

Second format: two digits, four letters, one digit, and four letters: The ninth character of the serial number represents the YEAR code, the tenth character represents the MONTH code and the eleventh character represents the WARRANTY period code. Example:

5 2 C B A C 8 D L W J

Decodes to 2010 (L), first half of November (W), 1 Year Standard Warranty (J).

The values in each position correspond to the following pre-determined year, month or warranty period codes. Note that there are two entries for every month: the first represents the first half of the month; the second represents the second half of the month.
