🔤 Speed Queen Serial Number Format

Speed Queen serial numbers encode the manufacture date in the first four digits. The first two digits are the 2-digit year (e.g., "18" = 2018) and the next two digits are the manufacturing week (01–52). Example: "1807XXXXX" = year 2018, week 07 (mid-February 2018). The remaining characters are the production sequence.

1807XXXXX

First two digits "18" = 2018, digits 3-4 "07" = week 7 (mid-February). Manufactured February 2018.

2135XXXXX

First two digits "21" = 2021, digits 3-4 "35" = week 35 (late August). Manufactured August 2021.

1452XXXXX

First two digits "14" = 2014, digits 3-4 "52" = week 52 (late December). Manufactured December 2014.

How Speed Queen Serial Numbers Work

Speed Queen is manufactured by Alliance Laundry Systems, headquartered in Ripon, Wisconsin. Unlike many appliance brands that moved manufacturing overseas, Speed Queen continues to produce the majority of its products in the United States. This American-made heritage is central to the brand's identity and its reputation for extreme durability — Speed Queen washers are rated for 25-year lifespans. The Speed Queen serial number format is refreshingly simple: the first two digits give the two-digit year, and the next two digits give the manufacturing week (01–52). There is no ambiguity about decade — the year digits uniquely identify the production year within a clear range. Week 01 is early January, and week 52 is late December. Speed Queen serials beginning with digits higher than the current year are likely older units using a different encoding. Commercial Speed Queen equipment may use a slightly different serial format than residential models — if this decoder gives unexpected results, consult the Alliance Laundry Systems documentation for your specific model.

Why Decode Your Speed Queen Serial Number?

Speed Queen serial decoding is important for warranty verification (Speed Queen offers industry-leading 5-year limited parts and labor warranties, with some models offering extended coverage), tracking commercial laundry equipment for lease or maintenance contracts, and determining parts compatibility. Because Speed Queen is known for long service lives, serial decoding helps distinguish between generations of parts that may not be interchangeable.

💡 Pro Tips

Speed Queen's simple year+week format makes it one of the easiest appliance serial numbers to decode manually. The brand's focus on durability means you may be decoding serials for units that are 10, 15, or even 20+ years old — all of which follow the same format. Commercial Speed Queen units in laundromats and apartment buildings use the same encoding.
