LG Serial Number Lookup

Enter a LG serial number to decode the manufacture year and month. Below the tool you will find the LG year-code table the decoder uses, worked examples, and an honest note on what the code cannot tell you.

The serial number is usually found on the back panel, inside the door, or under the lid of your appliance

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.

Documented worked example

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.

How to settle it: if you know roughly when the appliance was bought, or the property it came with was built, pick the candidate year closest to that. A unit still in service is far more likely to be from the most recent cycle — but not always, which is exactly why we show you the alternatives instead of hiding them.

Where to find the LG serial number

The serial number is printed on the rating label, usually alongside the model number. Depending on the appliance it may be inside the door frame, under the lid, behind a drawer or on the rear panel. Our label location guide shows where to look for each appliance type.
