In 2006, Whirlpool purchased Maytag. Since then, Whirlpool has been phasing out the Maytag Date Code. Hence, Maytag appliances manufactured after 2006, may have a Whirlpool Date Code.

Whirlpool Date Codes

The breakdown for Whirlpool Serial Numbers is:

1st Alpha Character = Manufacturing Division Code.
2nd Alpha Character = Year Manufactured (See Tables).
1st and 2nd Digit = Week of Year Manufactured.
3rd though 7th Digit = Order of Manufacturing that Week.

For products "not built by Whirlpool", an additional alpha is used after the first alpha to indicate the source. All other alpha and numeric designations remain the same.
