How do I find appliance age by serial number?

Select the brand, enter the serial number exactly as shown on the label, and run the decoder. Item Assist applies known brand formatting rules to estimate manufacture date and age.

What if I only have the model number?

Use Smart Lookup when the serial number is missing, worn, or unreadable. The model number plus a short description can still support a first-pass age and replacement workflow.

Where do I find the model and serial number on an appliance?

Most appliances place the label on a door frame, inside a compartment, behind a drawer, or on the rear/service panel. Item Assist also provides a dedicated model and serial number location guide.

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.
