Samsung Serial Number Lookup
Samsung is part of the Samsung. 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.
Decode schemes compiled from manufacturer literature and inspector references, cross-checked across two sources wherever possible (Samsung sources: howtolookatahouse + building-center.org (letter chart ends at K = 2018); building-center.org + homespy.io (letter chart ends at K = 2018)). Single-sourced rules are labeled low confidence instead of being presented as fact. 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 (chart verified 2001 through 2018 only) | 2001 to ~2018 verified | P1CP2473381 = 2007 (position 4 letter P) | medium |
| 15 characters; the letter at position 8 is the year (chart verified 2001 through 2018 only) | 2001 to ~2018 verified | see decoder | medium |
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 P1CP2473381
Expected decode: 2007 (position 4 letter P). Character by character:
P at position 4 = 2007 per the published Samsung year-letter chart (verified through K = 2018). The month code chart is not published.
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 Baseline
Registered within 60 days: 10-year parts / 10-year compressor with a 1-year labor allowance. Unregistered default: 5-year parts / 7-year compressor.

Frequently Asked Questions
How old is my Samsung unit?
Decode the serial number from the data plate. The dominant Samsung format (2001 to ~2018 verified) is: 10-11 characters; the letter at position 4 is the year (chart verified 2001 through 2018 only). Example: P1CP2473381 decodes to 2007 (position 4 letter P). Subtract the decoded year from the current year for the age. Units past 15 years are replacement candidates, and past 20 a major repair rarely pays off.
Why can a Samsung serial number decode to more than one date?
The main Samsung rule carries medium confidence, so treat the result as an estimate to check against the data plate. Some serial formats are genuinely ambiguous. Every reading that passes the validity checks (weeks capped at 53, months at 12, no future years) is shown ranked, instead of a coin flip presented as a fact.
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.
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. Decode the manufacture date above, then confirm coverage by running the full serial through the manufacturer's own warranty lookup. Terms shown are the current policy; older units often carried different terms.
Why do some Samsung serial numbers refuse to decode?
Samsung year letters are verified only through K = 2018. For newer units use the Manufactured date printed on the data plate. No verified Samsung reading matches this serial. Samsung's year-letter chart is documented only for the 10-11 and 15 character formats and only for 2001 through 2018 (letters through K); nothing is published for other lengths or newer letters. Use the Manufactured date printed on the data plate instead.
