Samsung Serial Number Lookup
Samsung's serial format is read from a document published by the company that built the unit. Enter the serial from the data plate below to get the manufacture date with a character-by-character explanation, the unit's age, its refrigerant era, and the warranty picture.
Starting the decoder. The serial formats, the refrigerant timeline and the warranty terms further down this page are already loaded, so you can read yours off them now.
Every serial format on this page is read from a document published by the company that built the unit, held as a retained copy. The manufacturer's document "Как узнать дату изготовления (производства) техники Samsung", Samsung's Russian-language page on finding the manufacture date, in its mobile-devices support section, which states the rule for "техники Samsung" (Samsung equipment) and says "Количество символов в серийном номере может быть различным" (the number of characters in a serial number can vary). A date stamped or printed on the data plate always outranks a serial decode.
Samsung Serial Number Formats
| Format | Era | Example | Confidence |
|---|---|---|---|
| 10-11 characters; the letter at position 4 is the year. The chart remark in parentheses describes the secondary references' chart. Samsung's own support page counts from the end of the serial: a final letter is ignored, then the seventh character from the end is the year letter and the sixth is the month (1 to 9, A = October, B = November, C = December). That lands on position 4 for a 10-character serial ending in a digit and an 11-character serial ending in a letter, which are the two this format readsCross-checked across 2 secondary references, alongside a manufacturer document held. Samsung's own support pages print the year letters from 2005, on its Ukraine page, through 2030, on its Russia page, repeating every twenty years.

| 15 characters; the letter at position 8 is the year. The chart remark in parentheses describes the secondary references' chart. Samsung's own support page counts from the end of the serial: a final letter is ignored, then the seventh character from the end is the year letter and the sixth is the month (1 to 9, A = October, B = November, C = December).

Some older or conflicting Samsung formats are recognized but deliberately not decoded; the decoder explains why when it sees one instead of guessing.
Worked Example: Samsung R38K503SR4
Expected decode: May 2018 (Samsung's own example). Character by character:
K at position 4 = 2018 on Samsung's own year-letter list
5 at position 5 = May (Samsung prints 1 to 9, then A, B, C for October to December)
Samsung Refrigerant Timeline
| Manufacture year | Typical refrigerant | Notes |
|---|---|---|
| through 2024 | R-410A | Samsung US mini splits and CAC ran R-410A through 2024. |
| 2025 and later | R-32 | Samsung chose R-32 for the 2025 transition, citing its European R-32 experience. |
The refrigerant printed on the nameplate is authoritative; this timeline tells you what is typical for the age, not what is in a specific unit.
Samsung Warranty Terms
Samsung warranty lookup
No page of Samsung's own for looking up a warranty is linked here, and this page does not read any maker's records, so it cannot show whether a unit was registered.
Enter the serial in the lookup on this page for the build date and the unit's age. No Samsung warranty certificate is held here for a dated term, so the result dates no term, says so, and names what would answer it; a Service Brief carries what is known to whoever works on the unit.
What this tool holds on Samsung's warranty
Registered within 60 days: 10-year parts / 10-year compressor with a 1-year labor allowance. Unregistered default: 5-year parts / 7-year compressor.
The result does not work out a dated term for Samsung: no Samsung certificate is registered for that here. Only the maker's records show whether a unit was registered.

Frequently Asked Questions
How old is my Samsung unit?
Decode the serial number from the data plate. The dominant Samsung format (2001 to present) is: 10-11 characters; the letter at position 4 is the year. Example: R38K503SR4 decodes to May 2018 (Samsung's own example). Subtract the decoded year from the current year for the age.
Has the Samsung serial decode been checked against serials somebody else dated?
No serial with a date published outside this tool has produced a reading through the Samsung 10-11 character and Samsung 15-character formats yet. Those formats are read from one document published by the company that built the unit.
Where the data plate prints a production date, that date has the final say.
What refrigerant does a Samsung unit use?
By manufacture year: through 2024: R-410A; 2025 and later: R-32. The refrigerant printed on the nameplate is authoritative; the year-based mapping tells you what is typical for the age, not what is in a specific unit.
How do I look up my Samsung warranty?
No page of Samsung's own for looking up a warranty is linked here, and this page does not read any maker's records, so it cannot show whether a unit was registered. Enter the serial in the lookup on this page for the build date and the unit's age. No Samsung warranty certificate is held here for a dated term, so the result dates no term, says so, and names what would answer it; a Service Brief carries what is known to whoever works on the unit.
Is my Samsung unit still under warranty?
Registered within 60 days: 10-year parts / 10-year compressor with a 1-year labor allowance. Unregistered default: 5-year parts / 7-year compressor. The result does not work out a dated term for Samsung: no Samsung certificate is registered for that here. Only the maker's records show whether a unit was registered.
Why do some Samsung serial numbers refuse to decode?
Samsung's year letters repeat every twenty years, so one letter can read two years; the Manufactured date printed on the data plate settles which. Samsung's own support page reads a serial from its end: a final letter is ignored, then the seventh character from the end is the year letter and the sixth is the month (1 to 9, then A, B, C for October to December). This tool reads that rule on a 10-character serial ending in a digit, an 11-character serial ending in a letter and a 15-character serial ending in a letter, so a serial of another shape, or one whose characters there are not a Samsung year letter and month, gets no date. Read the Manufactured date printed on the data plate instead.
