The serial number is on a sticker inside the door or on the back panel

The serial number on a Samsung washer dryer combo is printed on a white or silver sticker. On most models, this sticker is located on the inside of the door frame — look along the top or sides of the opening where the drum sits. On some models, particularly older ones, the sticker is on the back panel near the bottom, behind where the unit sits against the wall.

The sticker also holds the model number, which starts with "WD" for combo units. Both numbers are printed in black text. The serial number is typically a longer string of letters and numbers, often starting with a letter code that indicates the manufacturing date and location.

If the sticker has faded or peeled off, you may still see a faint outline or residue where it was. Take a photo of the area with good lighting — the number is sometimes visible even when the sticker itself is damaged.

Key Takeaways

  • Check the inside of the door frame first, along the top or sides of the opening.
  • If not there, look on the back panel near the bottom of the unit.
  • The serial number appears on the same sticker as the model number and is a longer string of letters and numbers.
  • Take a photo with good lighting if the sticker is faded, as the number may still be readable in the image.
  • You will need both the model number and serial number if you contact Samsung support or order replacement parts.

Why you need the serial number

The serial number identifies your specific unit and is required when you contact Samsung customer service, order replacement parts, or register your warranty. It tells the technician when your machine was made and which factory produced it, which matters because different production runs sometimes have different part configurations.

If your combo unit is still under warranty and you need a repair, Samsung will ask for the serial number before they schedule a technician or authorize parts. If you are ordering a replacement drum, motor, or control board, the parts department uses the serial number to confirm which version you need — the same part number can have variations depending on the year and region.

What to do if you cannot find the sticker

If the sticker is completely gone or unreadable, you have two options. First, check your purchase receipt or warranty paperwork — the serial number is often printed there. Second, look at any service records or previous repair invoices, which will also list it.

If you have none of those documents, contact Samsung directly with your model number and the date you purchased the unit. They can sometimes locate your serial number in their system if you provide the model and your contact information. You can reach Samsung support through their website or by calling the customer service number printed in your user manual.

Where the sticker location varies by model

Samsung has made washer dryer combos in several designs over the years, and the sticker location is not always identical. Most front-load combos have the sticker on the inside of the door frame. Some top-load models place it on the rim of the tub itself, visible when you open the lid. A few older models have it on the side panel or underneath the unit.

If you cannot find it in the obvious spots, open the door or lid fully and look at every edge of the opening. Shine a flashlight into corners and along seams. The sticker is always white or silver and always contains both the model number and serial number together.

Taking a clear photo for your records

Once you locate the sticker, take a photo that shows both the model number and serial number clearly. Use natural light or a flashlight to avoid glare on the sticker. A clear photo stored on your phone or computer is useful if you need to reference the number later and do not want to open the machine again.

Write down both numbers in a safe place as well — a notes app, a document, or a drawer where you keep appliance paperwork. If you ever need to contact support, have a repair done, or sell the machine, you will have the information when ready available.

What the serial number tells you

The serial number format varies, but it typically begins with a letter or two that indicate the year and month of manufacture, followed by a location code and a sequential production number. For example, a number starting with "A" might indicate January, while "L" might indicate December. The next letters often show which Samsung factory produced the unit.

You do not need to decode this yourself — it is mainly useful to Samsung technicians and parts departments. However, knowing the manufacturing date can help you understand whether your unit is still under the standard one-year warranty or an extended warranty you may have purchased.

Frequently Asked Questions

Is the serial number the same as the model number?

No. The model number identifies the type of machine — for example, all units of the same design have the same model number. The serial number is unique to your individual machine and identifies when and where it was made. Both appear on the same sticker.

Do I need the serial number to buy replacement parts?

You need the model number to order most parts. The serial number is helpful if you are unsure which version of a part you need or if the parts department wants to confirm your machine's exact configuration, but the model number is usually sufficient.

Can I find the serial number online if I bought the machine from a retailer?

Not usually. Retailers do not typically store serial numbers in their systems — they record the model number and purchase date. Your best source is the sticker on the machine itself, your receipt, or your warranty paperwork.

What if the sticker is under the machine where I cannot reach it?

If the sticker is on the back panel and the machine is against the wall, you may need to pull it out slightly to see it. If it is underneath, you may need to tilt the machine or use a mirror and flashlight to see it. Check your purchase receipt or warranty card first — that is usually faster than moving the unit.

How long do Samsung serial number stickers last?

The stickers are designed to last the life of the machine, but exposure to moisture, heat, and cleaning products can fade them over time. If yours is faded but still partially visible, a photo with good lighting often captures the number even when your eye cannot read it clearly.
