Where to find out the year of manufacture on the refrigerator: decoding the codes

The need to find out the exact production date of household equipment arises quite often, especially when buying used equipment or planning repairs. Many owners confuse year of manufacture with the date of sale, which leads to errors when calculating the service life and warranty. Manufacturers encrypt this information in long sequences of numbers and letters that are understandable only to service center specialists.

In most cases serial number contains all the necessary information, but it is impossible to read it without a key. Different brands use their own coding algorithms, so there is no universal formula. However, knowing the basic principles of labeling of popular factories, you can independently determine the age of the unit in a couple of minutes.

In this article we will analyze specific examples of decoding for the world's leading manufacturers. You will learn to find hidden stickers and understand the logic behind serial numbers. This knowledge will help you avoid buying an “old” new refrigerator that could have been sitting in a warehouse for a long time.

Location of identification plates

The first step in finding information is a physical inspection of the device case. Manufacturers place nameplate (metal or paper sticker) in places that are easily accessible, but not noticeable during normal use. Most often, this area is located inside the refrigerator compartment.

Pay attention to the side walls or the top of the internal volume. In some models, especially built-in ones, the sign may be moved to the end of the door or even to the back wall of the case. If there is nothing inside, check the outer back wall of the refrigerator, although the information there may be less readable due to dust.

On the plate itself, you are interested in the line with nad Serial No, S/N or “Serial number”. It is this combination of characters, usually consisting of 10–15 characters, that contains the encrypted date. A model codemay be indicated nearby, which is also sometimes useful for batch identification.

⚠️ Attention: Do not try to tear off stickers or scrape off dirt with sharp objects. If the information is not readable, try taking a photo in bright light and enlarging it on your computer screen - this often helps to make out erased characters.

There are several standard places where you should look for markings if you do not find them right away:

• 📍 On the inside side wall of the refrigerator compartment (most often on the left).
• 📍 On the inside of the door, closer to the hinges or handle.
• 📍 In a niche for a light bulb or under the egg shelf.
• 📍 On the outer back wall, next to the compressor (less convenient).

Secrets of marking Samsung refrigerators

The South Korean giant Samsung uses a fairly transparent coding system that is easy to learn. You need to find the last 8 characters in the serial number string. They are the ones responsible for the production date. The remaining characters indicate the model and manufacturer.

The first two digits of this eight indicate the year, and the next two indicate the month. For example, if the number ends with ...1905ABCD, then the release date is May 2019. However, there is a nuance: for older models (before the 2010s), the encoding could be different, and the year could be indicated by one letter.

It is important to distinguish between serial number and model code. The Model Code usually begins with letters indicating the type of device and contains information about color, volume and region of sale, but not the date. The date lies precisely in the long digital tail.

Let's consider the structure of the number using a specific example for clarity:

• 🔢 The first 6 characters: model and plant code.
• 🔢 Next 2 characters: year of issue (for example, 21 = 2021).
• 🔢 Next 2 characters: month of issue (01–12).
• 🔢 Remaining characters: unique copy number.

What to do if the number is not is it readable?

If the sticker is damaged, you can try to determine the production date by the component code, for example, by the production date of the compressor or electronic module, which are also marked. However, this requires disassembling the equipment.

How to decipher the code LG and Indesit

Refrigerators LG and Indesit (including the Hotpoint-Ariston brands) use a similar approach, where the first digits of the serial number are key. Unlike Samsung, here the date is often “hidden” at the beginning of the line, rather than at the end. This can confuse an inexperienced user.

For equipment LG the first two digits of the serial number usually indicate the year, and the next two - the month. For example, the number 1906... indicates June 2019. Sometimes the manufacturer uses a letter designation of the year, where A=2010, B=2011 and so on, but the digital format is more common in modern models.

Group brands Indesit Company (Indesit, Hotpoint, Ariston) often use a 22-character code. Here the production date is encoded in the first 7 characters. The first two digits are the year, the third and fourth are the week of the year (from 01 to 52). For example, the code 1523... means the 23rd week of 2015.

⚠️ Attention: When purchasing equipment from these brands, pay attention to the difference between the date of assembly and the date of release from the assembly line. Sometimes several months pass between these stages, which is important for counting the guarantee.

For easy comparison of encoding methods of different brands, we have compiled the data in a table:

Specifics of determining the age of Bosch and Siemens

German engineering, represented by the BSH concern (Bosch and Siemens), has gone its own way. Here serial number (E-Nr) does not contain a direct date in an understandable format. Instead, you need to look for a separate line FD or Fabrication Date, which is often located just below the main model number.

The date code for these brands consists of four characters. The first character is a letter representing the year. The countdown starts from 1995, where A=1995, B=1996, and so on. After the letter Z (2020), the cycle may repeat or change, so for equipment under 5 years old you need to be careful.

The second and third characters indicate the month. These can be numbers from 01 to 12. The fourth character often indicates the day or shift, but it is not critical for determining the age of the refrigerator. For example, the code K05 deciphers as 2019 (K is the 11th letter after A, 1995+24=2019? No, it’s more complicated here: A=95, B=96... K=2004? Let’s check: A=95, B=96, C=97, D=98, E=99, F=00, G=01, H=02, J=03, K=04. Stop, in new models Bosch uses a different code: A=2010, B=2011... K=2020. For Bosch equipment it is critical to know that the letter A can mean 1995, 2010, and 2020 depending on the decade, so always look at the overall age of the model.

In order not to get confused in the letter designations of decades, use the following algorithm:

• 📅 If the refrigerator looks modern (after 2010), consider A=2010, B=2011.
• 📅 If the equipment is old, then A=1995, B=1996.
• 📅 The letters I, O, Q are usually skipped in numbering.
• 📅 The month is always indicated in two digits immediately after the letter of the year.

Encoding features of Atlas, Atlant and Beko

Brands Atlant (former Minsk) and Atlas often use a simple digital sequence. In the serial number, the date can be placed in a separate field or encoded in the first digits. You often see a format where the first two digits are the year and the next two are the month, similar to LG. The Turkish brand (and its sub-brand Grundig) uses a system where the date is encrypted at the beginning of the serial number. Usually it is 6 or 7 digits. The first two are a year, the next two are a month. For example, Atlant Often there is a format where the first two digits are the year and the next two are the month, similar to LG.

Turkish brand Beko (and its sub-brand Grundig) uses a system where the date is encrypted at the beginning of the serial number. Usually it is 6 or 7 digits. The first two are a year, the next two are a month. For example, 2007... indicates July 2020. However, in some batches, the year may be indicated by a single digit to save space if the decade is obvious.

It is worth noting that for budget models of some brands, the sticker may be made in the form of a simple ink print, which fades over time. If you see a blurry spot where the number should be, try illuminating it with ultraviolet light (if available) or simply with a bright lamp at an acute angle.

⚠️ Attention: Technical specifications and labeling rules are subject to change by the manufacturer without notice. If you plan to buy spare parts, it is better to check the data at the official service center using the full VIN code of the device.

Why do you need to know the exact year of manufacture?

Many users ignore the production date, believing that the main thing is the date of purchase in the store. However, for complex equipment such as a refrigerator, downtime it matters. The compressor and refrigerant can degrade if the device has been sitting in a warehouse for years without being turned on.

Knowing the year of manufacture is also necessary when ordering spare parts. The design of shelves, doors or electronic modules may vary within the same model range. If you buy glass for a shelf from a 2018 model, and you have a 2021 unit, they may not fit the fastenings.

In addition, when selling used equipment, the seller’s honesty is highly valued. Indicating the real year of manufacture in the ad, confirmed by a photo of the nameplate, increases buyer confidence and speeds up the transaction. Hiding age by passing off warehouse storage as a new production is a short-sighted strategy.

In conclusion, it is worth saying that the ability to read the “language” of serial numbers is a useful skill. It allows you to look into the device's past before you even plug it into the network. This is especially true in conditions where store shelves may contain fresh deliveries and models released several years ago.

Is it possible to find out the year of manufacture by model?

It is impossible to accurately find out the year only by model (for example, RL34EBSW), since the same model can be produced for years. However, knowing the year of production of a particular model from open sources, you can approximately estimate the age if the equipment looks new.

What to do if the sticker is completely destroyed?

If the nameplate is missing, it is extremely difficult to determine the year of manufacture. You can try to find purchase documents, receipts or a warranty card. As a last resort, the date can be told at the service center using internal unit numbers if the equipment has been repaired.

Does the year of manufacture affect the service life?

Yes, it does. It is believed that equipment that has stood for more than 2-3 years without being turned on may require more thorough diagnostics before starting, especially for the compressor and seals.
