How do I decode a serial number?

Select your appliance brand from the dropdown, enter the full serial number exactly as shown on the product label, and click Decode. The tool applies the manufacturer's encoding rules to extract the manufacture date instantly.

Where is the serial number located on my appliance?

Serial number location varies by appliance. On refrigerators, check inside the fresh food compartment wall. On dishwashers, look on the inner edge of the door. Washers and dryers typically have it on the door frame. Ranges show it on the oven door frame. Water heaters display it on a label on the side of the tank.

How accurate is this serial number decoder?

For supported brands, accuracy is high when the full serial number is entered correctly. Some manufacturers reuse year codes on repeating cycles, which may result in two possible manufacture years being shown. In those cases, physical condition and model features can help confirm the correct decade.

Does this tool work for both appliances and electronics?

Yes. The decoder supports major home appliances including refrigerators, washers, dryers, dishwashers, and ranges, plus water heaters and electronics including Samsung and LG TVs. Use the Smart Lookup feature for brands or models not listed in the main tabs.

How this was determined

We use manufacturer serial format rules and published industry references to extract manufacture date information from serial numbers. Some brands reuse year codes across decades, which is why multiple valid years may appear. When two years are shown, the correct decade can typically be confirmed using physical condition, purchase records, or known installation dates.
