Gree serial number lookup

Selected North American Gree equipment uses a front-loaded week/year code. Imported and OEM product lines may use different labels, so the result includes a verification warning.

Gree date-code evidence

If you need to estimate a Gree unit’s manufacture age, identify the exact indoor or outdoor unit before reading the serial.

Separate North American Gree equipment from imported lines

A common North American style begins with production week followed by two-digit year (WWYY). The catalogued North American Gree family begins with production week followed by a two-digit year (WWYY). That verified family is separate from assumptions about every imported mini-split label. The verified North American Gree family uses production week followed by a two-digit year. Identify whether the plate is on a mini-split, PTAC, heat pump, or air conditioner before treating that front-loaded read as applicable.

Worked example: 4115GP00044

4115GP00044 — The verified decoder reads this fixture as Week 41 of 2015. The date is a manufacture estimate, not an installation date.

When Gree indoor and outdoor labels disagree

A split system can have separate indoor and outdoor labels, and imported or OEM products can use another serial format. Record both unit identities and use Gree support when the market or equipment family is unclear.

Model number vs. serial number

The model number identifies the Gree product and the serial identifies the physical unit; retain the indoor/outdoor pairing for support. For a split system, photograph the outdoor label first and keep the indoor-unit model and serial available for support.

Limits and official support

Imported and OEM Gree lines can use another serial format. If the result affects warranty, registration, parts, safety, or replacement decisions, use the complete model and serial with the manufacturer or a qualified professional. SerialAtlas is an independent reference, not an official warranty lookup or warranty coverage decision.

How to read a Gree serial number

A common North American style begins with production week followed by two-digit year (WWYY). SerialAtlas removes spacing and punctuation, then applies only the documented rule families mapped to Gree. The lookup remains in the browser.

Equipment covered

  • mini-splits
  • PTAC systems
  • heat pumps
  • air conditioners

Commercial, imported, very old, specialty, and private-label equipment can use a different code. Confirm the full rating plate before accepting a result.

Where to find the rating plate

  • Outdoor condenser or heat-pump cabinet, usually near the service valves
  • Inside the furnace or air-handler access panel
  • On the packaged-unit rating plate
  • Near the electrical disconnect or wiring diagram

Why more than one date can appear

Two-digit years and repeating letter cycles can point to more than one era. SerialAtlas ranks the plausible dates but keeps materially different alternatives visible. Label design, refrigerant, installation records, and product literature can resolve the era.

What this result does not prove

A manufacture date is not an installation date, warranty decision, recall match, condition assessment, or replacement recommendation. Confirm high-stakes decisions with the manufacturer or a qualified professional.
