Subject: HOSHIZAKI SERIAL NUMBER CODE
This is a revised version of SB93-0010. The purpose of this revision is to clarify the
serial number code and how it correlates to year and month of production.
To comply with a UL request, in 1993 we added a month code to our serial number.
We also implemented the use of a twenty-year serial number cycle however; this did
not take affect until the year 2001.
The standard Hoshizaki Serial number is a letter, 5 digits and a letter:
C
1
XXXX
A
Month
Jan = A
Apr =D
Jul = G
Oct = K
Feb = B
May =E
Aug = H
Nov = L
Note: The letter “I” is omitted
Continuous number
Auxiliary Code
Manufacturing year by last number
Note: “I” and “O” are omitted
Started back at “A” in 2011
on a 20 year cycle.
1 = A or L
2 = B or M
3 = C or N
4 = D or P
5 = E or Q
