How Whirlpool Encodes Age in Serial Numbers
Modern Whirlpool serial numbers typically feature 10 characters starting with a factory letter code. The second character indicates the manufacture year, and the third and fourth characters represent the calendar week of manufacture (weeks 01 through 52):
Example: Serial Number CY4510294
- 1st Character (
C): Manufacturing facility division code (Clyde, Ohio plant). - 2nd Character (
Y): Year code = 2009. - 3rd & 4th Characters (
45): Production week = Week 45 (early November). - Remaining Characters (
10294): Manufacturing sequence number for that production run.

Frequently Asked Questions
How do I read a Whirlpool serial number to find the age?
In standard Whirlpool 10-character serial numbers, the 2nd character represents the year of manufacture, and the 3rd and 4th digits represent the week of the year (01 to 52). For example, in serial CY4510294, 'Y' indicates 2009, and '45' indicates the 45th week of the year.
Does this serial decoder work for Maytag and KitchenAid?
Yes. Because Whirlpool Corporation manufactures Maytag, KitchenAid, Amana, and JennAir home appliances, all these brands utilize Whirlpool's unified 10-character manufacturing date code convention.
Where is the serial number located on a Whirlpool washing machine?
On front-load Whirlpool washers, open the door to find the rating label on the inner door frame or the cabinet opening. On top-load washers, look under the lid along the rear frame or on the back upper console.
