Determining the exact production date of household appliances is not just an idle curiosity of the owners, but often a necessary measure for proper operation. Knowing exactly when your unit was manufactured is critical when searching for original parts, ordering rare filters, or trying to find compatible electronics for repair. Owners are often faced with a situation where the appearance of the model has not changed for years, but the internal filling is radically different.
Many users mistakenly believe that it is enough to know only the model of the device. However serial number contains much more information than just a unique identifier. It is in this sequence of letters and numbers that manufacturers encrypt the date of assembly, place of production, and sometimes even the shift number. Understanding these codes allows you to weed out unsuitable parts at the ordering stage.
In this article we will analyze decoding algorithms for the most popular brands on the market. You will learn to find hidden markings and understand why the age of equipment affects the cost of its maintenance. Let's figure out where to look for information and how to interpret it correctly.
Where to look for the serial number and markings
The first and most important step is the physical detection of the sticker or metal nameplate. Manufacturers do not always place them in the same places, which often confuses the untrained user. Most often, look on the the back wall casing, but in modern built-in models, access there may be blocked.
If there is nothing behind, inspect the inside of the refrigerator compartment. Pay attention to the left or right side wall, as well as the space inside the door. There may be a sticker with the brand logo and a long code. The marking is also often found on the base panel at the bottom, next to the compressor.
⚠️ Attention: Never use abrasives or sharp objects to clean a dirty sticker. Aggressive chemistry can erase important information, making the code unreadable.
Sometimes the sticker can be damaged by time or moisture. In such cases, it is worth checking the technical passport of the product, if it has been preserved. Also, data on the date of purchase and, indirectly, the year of manufacture are often contained in the warranty card, which is filled out in the store.
Deciphering codes from manufacturers in Europe and the USA
European brands, such as Bosch, Siemens and Liebherr, use fairly logical coding systems. Typically, the first digits of the serial number indicate the year of manufacture. For example, a company Bosch year is often encoded in the first two or three digits of a long FD code.
For equipment Whirlpool and Hotpoint the use of alphanumeric combinations is typical, where the letter indicates the year and the numbers indicate the week of production.
American manufacturers, including General Electric (GE) and Frigidaire, often hide the date at the beginning of the serial number. For GE, the first letter is the year, the second is the month. Such a system allows you to quickly identify the age of the device without complex calculations.
Liebherr marking nuances
For Liebherr refrigerators, the serial number often begins with a prefix, followed by numbers. The year of manufacture is usually indicated as the 4th and 5th digits on the line, but the system may vary depending on the assembly plant.
It is worth considering that the globalization of production has led to the fact that the same brand can use different plants in different countries. Therefore, encoding algorithm may differ even for identical models assembled in Poland and Germany.
Labelling features of Asian brands
Asian giants like Samsung, LG i Haier apply their own unique standards, which often confuse European users. The Samsung serial number usually consists of 15 characters. The first two characters are the model code, and the next two indicate the year of manufacture. For example, the code "19" would indicate 2019.
The Company LG uses a format where the first three digits of the serial number indicate the date. The first digit is the year (last digit of the year), the second and third are the month. However, for a complete decoding you need to know the decade, which is often determined by the year the model entered the market.
- 📅 U Samsung look for the 3rd and 4th digits in the code to determine the year.
- 📅 LG encodes the year with the first digit, but requires knowledge of the decade of release.
- 📅 Haier often uses An 8-digit code, where the first two digits are the year.
- 📅 In Electrolux (Poland/Hungary assembly), the first two digits of the code after the letters are the year.
It is important not to confuse the model code and the serial number. The Model Code is usually shorter and repeated on all devices of the same batch, while the Serial Number is unique for each unit.

Russian brands and CIS equipment
Domestic manufacturers, such as Indesit (Russian assembly), Beko (factories in the Russian Federation) and Atlantalso have their own systems. Belorussian Atlant often indicates the production date directly on the sticker in the format DD.MM.YY, which greatly simplifies the task.
In Russian factories Indesit i Ariston the encoding may repeat the European standards of the parent company, but adjusted for localization. Often there is a format where the year is encrypted with a letter at the beginning or middle of the line.
To accurately determine the age of equipment produced in the CIS, sometimes it is enough just to look at the design features. For example, a change in the type of refrigerant from R134a to R600a occurred in certain years, which can serve as an indirect indication of the release date.
⚠️ Attention: When purchasing used equipment, pay attention to the condition of the rubber seals and plastic elements. If a 2010 refrigerator looks like new, but the seal is fossilized, this is a reason for suspicion.
Some factories start numbering again every year or use cyclic codes. Therefore, knowing the exact serial number serial number is critical for requesting the manufacturer's support service.
Year of manufacture code correspondence table
Below is a summary table that helps you quickly navigate the designations of some popular brands. Remember that manufacturers can change standards, so the data is for reference only.
| Brand | Code format | Where to look for year | Example |
|---|---|---|---|
| Bosch / Siemens | FD + numbers | First 2 digits after FD | FD88.. (2018) |
| Samsung | 15 characters | 3rd and 4th digits | ..19.. (2019) |
| LG | Letters and numbers | 1st digit (year) | 7.. (2017 or 2007) |
| Electrolux | 343.. + numbers | 2nd and 3rd digits of the code | ..13.. (2013) |
| Atlant | Numeric | Separate date field | 12.05.2020 |
Use this table as a primary guide. If your code does not fit any of the schemes, perhaps the model was produced on a special order or belongs to a rare series.
Why is it important to know the exact age of the refrigerator
Knowing the year of manufacture is necessary not only for curiosity. The main reason is this compatibility of spare parts. Compressors, control boards and even shelves may differ between different years of production of the same model. Ordering a part based on a photo without taking into account the year often leads to errors.
This also affects the assessment of equipment life. The average service life of a modern refrigerator is 10-15 years. If you buy a device that is already 12 years old, you should be prepared for the possible failure of the main components in the near future.
☑️ Check before buying used
In addition, age affects energy efficiency. Refrigerators manufactured more than 10 years ago consume significantly more electricity than modern class models A+ or A++.
What to do if the sticker is lost or unreadable
In a situation where the marking is completely missing, you can only rely on indirect signs. First of all, check the documents: warranty card, instructions or receipt. The date of purchase usually coincides with the year of manufacture or is several months away from it.
You can contact an authorized service center. Engineers often have access to databases of design changes. By describing the external signs, the location of the buttons, the type of defrosting and the color, a specialist can approximately determine the production period.
⚠️ Attention: Do not try to open the back panel yourself to look for numbers on the compressor if the equipment is under warranty. This will lead to loss of warranty.
Another method is to search for reviews or catalogs on the Internet using the exact model name. Often, old store catalogs indicate the years when a particular model was actively sold. This will allow you to determine the production time range.
Frequently asked questions (FAQ)
Can you find out the year of manufacture by the model number?
The Model Number itself rarely contains a direct date. It indicates the series and characteristics. However, knowing the model, you can find the year of its production in open sources or catalogues.
Does the country of assembly affect the date encoding?
Yes, this is a very important factor. The same brand (for example, Bosch or Electrolux) may be used by different factories in different countries, and each factory may use its own standard for marking serial numbers.
How many years does the average refrigerator last?
The average service life of modern refrigerators is from 10 to 15 years, provided they are used correctly. Chinese budget models may last less, while premium European brands often last longer.
Where is the serial number for a built-in refrigerator?
For built-in appliances, access to the back wall is blocked by furniture. Look for a sticker on the inside wall of the refrigerator compartment, on the end of the door or on the plinth below, which can be removed without dismantling the cabinet.
Is it true that old refrigerators are better than new ones?
This is a myth. Old Soviet refrigerators were very reliable, but uneconomical and noisy. Modern models are quieter and more economical, although their service life may be shorter due to the complexity of the electronics and the use of thinner materials.
