Stone Island ART numbers are product reference codes found on garment labels. They can be useful when researching a pre-owned piece because older ART numbers can help narrow down the production season, product line and broad garment type.
They are not an authentication code. A plausible ART number can support product research, but it should never be treated as proof that a Stone Island garment is genuine.
Where can you find a Stone Island ART number?
On many Stone Island garments, the ART number appears on the internal care or wash label. It can also appear on original swing tags when those are still present. Older labels often print the reference after the word ART, while newer product references can use alphanumeric formats.
What can an ART number tell you?
Collector-documented legacy references often contain information that helps identify the season, line, broad garment category and individual production reference. The format changed over time, so it is safest to use the ART number as one piece of evidence rather than a universal decoder.
How older season codes are commonly read
Important: Stone Island does not publish a complete public decoder for this legacy format. The season pattern below is based on long-running independent collector documentation and is best used as a research aid, not as official authentication evidence.
On the commonly documented older numeric system, the first two digits identify a collection season. Even-numbered season codes correspond to Spring/Summer and the following odd-numbered code corresponds to Autumn/Winter of the same year.
| ART prefix | Commonly documented collection |
|---|---|
| 46 | Spring/Summer 2007 |
| 47 | Autumn/Winter 2007 |
| 48 | Spring/Summer 2008 |
| 49 | Autumn/Winter 2008 |
| 60 | Spring/Summer 2014 |
| 61 | Autumn/Winter 2014 |
| 62 | Spring/Summer 2015 |
| 63 | Autumn/Winter 2015 |
This legacy pattern is useful for older pieces, but it should not be applied blindly to recent alphanumeric references.
What about the rest of the code?
Older references can also help narrow down the Stone Island line and product category. Collector resources commonly associate certain positions in the code with ranges such as mainline, Junior or Shadow Project. Because Stone Island does not publish a complete public decoder for every historical format, use these patterns cautiously and cross-check the garment itself.
Why do newer Stone Island references look different?
Recent official Stone Island product pages use alphanumeric references. If a code begins with letters, research the full reference rather than trying to force it through an older two-digit season table.
ART number vs Certilogo
The two codes serve different purposes. An ART number is a product reference. Certilogo is an authentication service. Stone Island states that Certilogo has been used on Stone Island and Stone Island Shadow Project garments since Spring/Summer 2014, with later coverage for Junior; some product families are exceptions.

Can a correct ART number prove a garment is genuine?
No. Counterfeit garments can copy real product references, while unusual or difficult-to-find codes can also appear on genuine older pieces. Authentication should consider the garment as a whole: labels, construction, materials, hardware, badge, product details and, where applicable, the official Certilogo result.
How ART numbers help when buying pre-owned Stone Island
A useful reference can make a listing much easier to research. It may help confirm whether the stated season is plausible, lead to archive references for the same model, or identify a fabric or treatment used on the piece.

ART number FAQs
Where is the ART number on a Stone Island jacket?
Usually on the internal care or wash label, and sometimes on original swing tags.
Does every ART number use the same format?
No. Formats have changed over time and recent references can be alphanumeric.
Can I authenticate Stone Island from the ART number?
No. ART numbers help with identification and research, not authentication.
Why does my code not work in an online checker?
The garment may use a newer format, an unusual older reference, or the checker may not contain that code. A failed lookup is not automatic evidence that the item is fake.
