On a standard 15-character Samsung appliance serial number, the 8th character is a year code letter and the 9th character is the month (1–9 for January–September, then A = October, B = November, C = December). So a serial whose 8th and 9th characters are J7 decodes to July 2017. Shorter 11-character Samsung serials put the year digit in position 5 and the month code in position 6. This works for Samsung refrigerators, washers, dryers, dishwashers, and ranges. Here is the full decoding table with examples.
Free Samsung Serial Number Decoder
The quickest way is our free Appliance Age Decoder. Select “Samsung,” enter the serial number, and get the manufacture date, age, and estimated remaining lifespan instantly. It handles both the 15-character and 11-character formats automatically.
Where to Find Your Samsung Serial Number
| Appliance | Label Location |
|---|---|
| Refrigerator | Inside the fresh-food compartment, on the left interior wall or behind the crisper drawers |
| Washer | Around the door rim (front-loaders) or under the lid (top-loaders); also on the rear panel |
| Dryer | Inside the door rim or on the rear panel |
| Dishwasher | On the edge of the door or the side of the tub, visible when the door is open |
| Range / oven | On the oven door frame, behind the storage drawer, or on the rear |
| Microwave | Inside the door frame or on the rear/underside |
The label shows a model number (like RF28R7351SG) and a serial number (a 15-character mix of letters and digits, sometimes with a barcode). You want the serial number.
How to Decode a 15-Character Samsung Serial Number
Count to the 8th character for the year and the 9th for the month.
Month codes (9th character):
| Code | Month | Code | Month |
|---|---|---|---|
| 1 | January | 7 | July |
| 2 | February | 8 | August |
| 3 | March | 9 | September |
| 4 | April | A | October |
| 5 | May | B | November |
| 6 | June | C | December |
Year codes (8th character): Samsung’s year letters repeat on roughly a 20-year cycle, so each letter has two candidates — but only one is plausible for an appliance still in service:
| Letter | Year | Letter | Year |
|---|---|---|---|
| R | 2001 / 2021 | B | 2011 / 2031 |
| T | 2002 / 2022 | C | 2012 / 2032 |
| W | 2003 / 2023 | D | 2013 / 2033 |
| X | 2004 / 2024 | F | 2014 / 2034 |
| Y | 2005 / 2025 | G | 2015 / 2035 |
| A or L | 2006 / 2026 | H | 2016 / 2036 |
| P | 2007 / 2027 | J | 2017 / 2037 |
| Q | 2008 / 2028 | K | 2018 / 2038 |
| S | 2009 / 2029 | M | 2019 / 2039 |
| Z | 2010 / 2030 | N | 2020 / 2040 |
In practice the ambiguity resolves itself: the second candidate is in the future (or the appliance would be 20+ years old, which its condition usually rules out). Our Appliance Age Decoder picks the plausible year automatically.
Worked Examples
Example 1: serial 0B1G5**J7**BC00251 (8th–9th characters bolded)
- J = 2017
- 7 = July
- Manufactured July 2017
Example 2: 8th–9th characters MB
- M = 2019
- B = November
- Manufactured November 2019
How to Decode an 11-Character Samsung Serial Number
Some Samsung appliances carry a shorter serial. On these:
- Position 5: last digit of the year
- Position 6: month code (same 1–9, A, B, C table as above)
Example: positions 5–6 read 84 → year ending in 8 (2018 for a unit of recent vintage), April → Manufactured April 2018. Because a single digit repeats every decade, sanity-check against the appliance’s apparent age, or let the Appliance Age Decoder resolve it.
What Your Samsung Appliance’s Age Means
| Appliance | Typical Lifespan | Details |
|---|---|---|
| Refrigerator | 10–15 years | How Long Does a Refrigerator Last? |
| Washer / dryer | 10–13 years | How Long Do Washers and Dryers Last? |
| Dishwasher | ~10 years | How Long Does a Dishwasher Last? |
Age matters most when a repair quote lands: a $400 repair on a 3-year-old refrigerator is an easy yes; the same repair on a 13-year-old unit usually is not. Our Repair or Replace tool and refrigerator repair cost guide walk through the decision.
Frequently Asked Questions
Why does Samsung’s warranty matter here?
Samsung refrigerators with digital inverter compressors carry a 10-year compressor warranty (part only) in most product lines. Decoding the manufacture date tells you whether that clock has run out before you pay for a compressor diagnosis. Warranty terms vary by model and registration — confirm yours with Samsung using the full serial number.
Is the manufacture date the purchase date?
No. Appliances typically sell weeks to a few months after manufacture. Samsung’s warranty runs from the purchase date (keep your receipt); the serial-number date is your fallback evidence and the honest baseline for judging remaining lifespan.
My Samsung serial doesn’t match either format. What now?
A handful of Samsung lines and OEM-built products deviate. Try the Appliance Age Decoder, check for a printed date on the label itself (some labels state a manufacture date outright), or contact Samsung support with the model and serial.
My Samsung is throwing an error code. Is that age-related?
Not necessarily — see our error code lookup hub to decode it. Common examples: a washer 5C/SC code is a drain problem (washer not draining guide), and ice-maker faults on French-door refrigerators are a known pattern we cover in Ice Maker Not Working.
