Finding identification data for household appliances often turns into a real quest, especially when the label is lost, erased or removed during a move. Refrigerator serial number is not just a set of random numbers, but a unique code that contains information about the production date, manufacturer and specific modification of the device. Understanding where it is located and how to read it becomes critical when ordering spare parts, filing an insurance claim, or checking the authenticity of a unit on the secondary market.
Owners often confuse model and serial number, which leads to selection errors components. The model indicates the series and functional features, while the serial number (S/N) is individual for each specific instance. The serial number is never repeated even within the same production batch. Ignoring this difference may result in you ordering the wrong compressor or control unit that will not physically fit into place.
There are several standard places where manufacturers place information labels, but their location greatly depends on the brand and year of manufacture of the equipment. In this article, we will analyze in detail the algorithms for searching for markings for various brands, learn how to decode encrypted information and use online services to check the device status. This knowledge will help you avoid fraud and accurately determine the age of your equipment.
Where to look for the number plate: main locations
The first place you should look is the inner chamber of the refrigerator. Manufacturers prefer to place technical data stickers on the side walls so that they are accessible without having to move the heavy unit. Most often, look for markings on the left or right wall between the shelves; sometimes they are hidden behind plastic stops or decorative strips. In some models Samsung i LG the sticker may be located on the inside of the door, closer to the hinges or handle.
If the inside of the chamber is clean and empty, inspect the back wall of the refrigerator. A metal plate or paper sticker is often attached to the top, near the outlet of the refrigerant or electrical cable. Getting there is more difficult: you will need to move the refrigerator away from the wall, which is not always convenient in a kitchen. However, this is where information is often saved if the internal label was damaged during careless washing or defrosting.
- 📍 The inner left or right wall of the cooling chamber.
- 📍 The inner surface of the door (often near the handle or hinges).
- 📍 The rear metal wall of the case (in the upper part).
- 📍 Basement part in front (decorative grille is removed).
It is worth considering that in built-in models, access to the rear wall is almost impossible without dismantling the kitchen unit. Therefore, for such equipment, manufacturers duplicate information on the front panel or use digital identification methods. If you did not find the sticker in any of the listed places, it may have been removed by the previous owner or become unusable over time.
Specifics of marking for popular brands
Each manufacturer has its own corporate standards for the preparation of technical documentation. For example, for Siemens equipment, the serial number often begins with the prefix “FD”, followed by a production date code. In Bosch And The Siemens serial number often begins with the prefix "FD" followed by a production date code. U Indesit and Ariston (now Haier), the encoding can be more complex, using the letter designations of the assembly plant. Understanding these nuances allows you to quickly navigate the sea of symbols.
In refrigerators Electrolux and Zanussi there is often a division into “Product Number” (PNC) and “Serial Number”. For ordering spare parts in the service centers of these brands, it is the PNC that is critical, which is usually longer and contains more numbers. An error in one digit of this code can lead to ordering a part from a different modification, since PNC determines the exact configuration, including the color of the handles and the type of plastic. Asian manufacturers, such as Samsung and Daewoo, often hide information in hard-to-reach places or use non-standard formats. For some Samsung models, the sticker may be located at the end of the door, hidden by a seal. In such cases, it is recommended to carefully bend the rubber profile to ensure that the markings are present. Also, Korean brands often have duplication of data in the electronic menu.

⚠️ Attention: Never use aggressive chemicals to clean the sticker inside the camera. Solvents can erase the information, leaving you without the ability to identify the device.
How to decipher the serial number and production date
The serial number is an encrypted message from the plant engineers. Unlike the model, which remains the same for thousands of vehicles, the serial number is unique. In most cases, the first few characters indicate the plant and year of manufacture. For example, if the number starts with "1", it could mean 2021 or 2011, depending on the manufacturer's cycle. Letter designations often indicate the month of production: A - January, B - February, and so on, sometimes omitting the letter "I" so as not to be confused with one.
For accurate decoding, you need to know the algorithm of a specific brand. U Whirlpool date is often encrypted in the last digits of the combination. Liebherr uses a clear system, where the year and week of production are indicated explicitly or encoded as the first characters after the prefix. Knowing the production date, you can determine the service life of the main components: for example, if the refrigerator is already 15 years old, replacing the compressor may not be economically feasible.

Below is a table with examples of serial number formats for various manufacturers. Please note that formats may vary depending on the year of manufacture of a particular line.
| Brand | Format example | Where to look for the date | Features |
|---|---|---|---|
| Bosch / Siemens | FD 9810 12345 | First 4 digits after FD | Year = 9+8 (1998 or 2008), Month = 10 |
| LG | 908KWE12345 | First 3 digits | 9 = 2009, 08 = August |
| Samsung | 1234ABCD5678 | Depends on the model | Often a decoder or service book is required |
| Indesit / Ariston | 12345678901 | The first 2 digits | The first digit is the year, the second and third are the week |
| Electrolux | 934 123 456 00 | In the PNC code | PNC is more important than S/N for spare parts |
Sometimes you can find several lines with numbers on the sticker. It is important not to confuse Part Number (part number or article) with the serial number of the unit itself. The serial number is usually marked "S/N", "Serial No" or "No". If in doubt, it is better to take a photo of the entire sticker and show it to a specialist at the service center.
What to do if the code is not readable?
If the numbers are erased, try illuminating the sticker with a bright light at an acute angle or using an ultraviolet lamp. Sometimes remnants of paint or dented ones allow you to restore lost information.
Checking authenticity and warranty status
Checking the refrigerator by serial number is a mandatory procedure when purchasing equipment second-hand or in discount stores where refurbished samples can be sold. Official websites of manufacturers often have a “Support” or “Check Warranty” section where you can enter your S/N. The system will display the warranty activation date, sales region and device status. If the system writes “Not Found” or shows a model different from yours, this is an alarming signal.
Chinese copies of well-known brands often have serial numbers printed in a different font from the original, or with grammatical errors in the accompanying text on the sticker. The original always has clear printing, durable paint and smooth label edges. Fake numbers may not appear in the international database, which makes it impossible to order original spare parts in the future.
- 🔍 Go to the manufacturer's official website in the support section.
- 🔍 Enter the serial number in the warranty check field.
- 🔍 Compare the model displayed on the website with the real model your refrigerator.
- 🔍 Pay attention to the region: if the refrigerator is “European”, but it appears as “Asian”, this may be parallel import.
Also, the check helps to identify “gray” imports. Equipment intended for Asian or African markets may have different climate classes and compressor voltage. Using such a refrigerator in conditions for which it is not intended will shorten its service life. The serial number will tell the whole truth about the origin of the unit.
What to do if the sticker is lost or unreadable
The situation when the marking is completely destroyed is not uncommon. In this case, do not despair. First of all, check the documentation: warranty card, user manual or box (if it is still available). Often, when selling, the store puts a stamp on the warranty card with the serial number and model written in by hand. This data is legally significant and can be used to confirm ownership.
If there are no documents, you can try to find information in the electronic menu of modern “smart” refrigerators. Many models with displays allow you to display technical information through the service menu. This is usually done using a combination of buttons on the control panel. For example, pressing the "Freezer" and "Cooling" buttons simultaneously for 5-10 seconds can display service data, including the full S/N and error code.
Example of entering the service menu (not for all models):Press and hold: Freezer + Cooling (10 sec)
Or: F + C (until the beep)
Menu: All Display On -> Version code -> Serial No.
In extreme cases, when there are no stickers, no documents, no access to the menu, only visual identification by a specialist remains. The repairman will be able to determine the model by the internal structure, compressor type, evaporator location and electronic module. However, this takes a long time and is not always accurate. Therefore, careful handling of the nameplate is in the interests of the owner.
⚠️ Attention: Do not try to break the protective seals on the compressor or control unit yourself in search of the number. This may break the tightness of the system or lead to electric shock.
☑️ Actions if the sticker is lost
Frequent errors when identifying the model
One of the most common mistakes is trying to find the number on the outside of the case. Manufacturers rarely place permanent markings there so as not to spoil the design. Another mistake is confusion between the model number and the lot number. The model (for example RL34EBSW) is the same for thousands of refrigerators, and the serial number is unique. When ordering spare parts, especially electronic circuit boards and doors, a unique number is often required.
Also, users often ignore additional stickers on energy-saving classes. Sometimes brief information is duplicated on the energy label, which is glued to the facade upon sale. If the main sticker inside the camera has worn off, the label on the door can be a lifesaver, although it is less informative and easier to come off.
You should not rely on memory or notes in a notebook if you plan to order spare parts online. One wrong number in the article or serial number will result in the part not fitting. Always double-check the data immediately before placing an order, best of all by taking a close-up photograph of the sticker.
FAQ: Frequently Asked Questions
Is it possible to find out the year of manufacture of a refrigerator without a sticker?
It is extremely difficult to do this without a sticker or documents. Theoretically, you can date the device by the year of manufacture of a specific compressor or electronic board, if you know their part numbers, but this requires deep disassembly and specialist knowledge.
What to do if the serial number does not match the model?
This may indicate that a control board or other component from another device is installed in the refrigerator (for example, after unqualified repairs). In this case, you need to focus on the physical case and the main sticker on the camera.
Where can you find the serial number on a built-in refrigerator?
For built-in models, the sticker is most often located on the end of the door (side) or on the inner wall of the chamber. Access to the back wall is blocked by furniture, so markings are almost never placed there.
Why do you need a PNC code if there is a serial number?
Product Number Code (PNC) is used primarily by brands Electrolux, Zanussi, AEG for accurate selection of spare parts. The serial number may be common for the line, and the PNC indicates a specific modification, color and configuration.
