How LG serial numbers encode the date
LG does not print the manufacture date in plain text on most units — it is encoded into the serial number. The decoder recognises one format for this brand:
Last digit of the year, then the month
The 1st character is the last digit of the year, and the 2 digits starting at the 2nd character are the month.
Applies to serial numbers of at least 3 characters.
| Year code | Means |
|---|---|
| 0 | 1990 · 2000 · 2010 · 2020 |
| 1 | 1991 · 2001 · 2011 · 2021 |
| 2 | 1992 · 2002 · 2012 · 2022 |
| 3 | 1993 · 2003 · 2013 · 2023 |
| 4 | 1994 · 2004 · 2014 · 2024 |
| 5 | 1995 · 2005 · 2015 · 2025 |
| 6 | 1996 · 2006 · 2016 · 2026 |
| 7 | 1997 · 2007 · 2017 · 2027 |
| 8 | 1998 · 2008 · 2018 · 2028 |
| 9 | 1999 · 2009 · 2019 · 2029 |
Worked examples
Each example below is decoded by the same engine that powers the tool on this page, so what you see here is exactly what you would get by typing it in.
This tool returns March 2026 · medium confidence
The same code could also mean 1996, 2006, 2016.
Owner confirmed March 2016, not 2026 — the true year is one of the alternates listed above.
A dryer from LG's published worked example. The month is exact. The decade is not written anywhere in an LG serial, so the year shown is the most recent one the code can mean — here the true year is one cycle back.
Why the year can be ambiguous
LG reuses the same year character across repeating cycles, so one character on its own cannot pin down an absolute year. When that happens the tool picks the most recent year that has already occurred, marks the result medium confidence, and lists the other years the same code could mean.
Where to find the LG serial number
The serial number is printed on the rating label, usually alongside the model number — never on the front of the appliance where you would look first. Where that label sits depends on what the appliance is:
| LG appliance | Where the rating label usually is |
|---|---|
| Refrigerator | Inside the fresh-food compartment on a side wall; near the upper shelf; behind crisper drawers; or on the exterior side/rear panel. |
| Washer | Front-load: on the cabinet or door frame behind the open door, near the hinge, or on the rear panel. Top-load: under the lid near a hinge, on the rear console, or near the water-inlet connections. |
| Dryer | Around the drum opening behind the door; on the cabinet side; or on the rear panel. |
| Dishwasher | On the left, right or top edge of the door; on the tub frame; sometimes on the kick plate. |
| Range / Oven | On the frame behind the oven door; behind the lower drawer; beneath the cooktop; or on the rear panel. |
| Microwave | Inside the door frame or cavity wall; on the vent grille housing for over-the-range models. |
Photograph the label rather than copying it by hand. The character that carries the year is one of about a dozen on the line, and a 0 read as an O costs you the lookup. Our label location guide has the same guidance for every brand.
Common questions about LG appliance age
How old is my LG refrigerator?
Read the serial number off the rating label and type it into the tool at the top of this page. It returns the month and year the unit left the factory, which is not the day it was sold: an appliance commonly spends six to twelve months between the production line and a kitchen, and clearance stock far longer.
Does a LG serial number contain the manufacture date?
Yes, but encoded rather than printed. LG carries the date in one format, where one character stands for the year and another for the month. The tables above name those positions, so you can check the tool's answer by hand.
Where is the serial number on a LG refrigerator?
Inside the fresh-food compartment on a side wall; near the upper shelf; behind crisper drawers; or on the exterior side/rear panel. It sits on the same label as the model number. Photograph it — misreading one character is the usual reason a lookup fails.
Why does the tool show more than one possible year?
LG reuses year characters on a cycle, so a single character cannot separate, say, 2005 from 2025. The tool shows the most recent year that has already passed and lists the alternatives rather than hiding the doubt. If you know roughly when the appliance was bought, the candidate nearest that date is the right one.
