Compaq branded products are assigned a unique serial number consisting of twelve alphanumeric
characters. The serial number convention defines what each character in the serial number represents.
While the length of the serial number has remained a constant twelve characters since the start of
production, the serial numbering convention has been updated periodically in order to increase the number
of possible unique combinations (or numbers) availble to be assigned to products.
-004 SERIAL NUMBERING CONVENTION (EFFECTIVE 1/1/1996 - PRESENT)
This specification defines the requirements for SERIALIZATION OF TOP ASSEMBLIES in the Compaq
manufacturing system. The serial number scheme consists of 12 characters (alpha or numeric) and is
defined as follows:
S
Y
WW
CCCC
ZZZZ
S is a site code and denotes the site of manufacture as well as defining the location where the necessary
agency follow-up inspection and all agency required testing is performed. Site codes can be either
numeric or alpha.
Y is the last digit of the year in which the product was produced.
W is the week in which the product was produced.
C is the configuration code that defines the specific computer as shipped out of our factory.
Z is the serial number which allows both service and the factory to differentiate between units produced in
the same week.
-005 SERIAL NUMBERING CONVENTION (EFFECTIVE 6/1/1998 - PRESENT)
This specification defines the requirements for SERIALIZATION OF TOP ASSEMBLIES in Non-Compaq
owned Manufacturing Facilities. The serial number scheme consists of 12 characters (alpha or numeric) and
is defined as follows:
SS
Y
M
CCCC
D
ZZZ
SS is a two-digit site code and denotes the site of manufacture as well as defining the location where the
necessary agency follow-up inspection and all agency required testing is performed. The second digit
of the site code can ONLY be alpha and NOT numeric.
Y is the last digit of the year in which the product was produced.
M is the Month in which the computer was built (Ex: 1, 2…9, A, B, C)
C is the configuration code that defines the specific computer as shipped out of our factory.
D is the first Digit of the Serial Number and represents the Day in which the unit was produced by utilizing
a series of characters. This first character uses Base 31 (Ex: 1,2…9, A,B,C…Z, this code EXCLUDES
I, O, Q, U)
Z is the serial number which allows both service and the factory to differentiate between units produced in
the same week.
