Stellantis Certificate of Conformity (CoC): Brands Covered and What to Do Next
If you’re importing or registering a vehicle in Europe, a Stellantis Certificate of Conformity (CoC) can be the document that makes the process smooth—or painfully slow if you request the wrong one. Here’s exactly which brands are covered, what “Stellantis CoC” means in practice, and how to request the correct COC certificate by VIN.
What “Stellantis CoC” actually means
People search for Stellantis CoC, Stellantis certificate of conformity, or “COC certificate Stellantis” when they need an EU document to register a car that belongs to a Stellantis brand. That’s the key point: the CoC is issued for a specific vehicle under its brand and EU type-approval—not as a generic “Stellantis document”.
In other words, you’ll request a Fiat CoC, Peugeot CoC, Citroën CoC, Opel CoC, Jeep CoC, Alfa Romeo CoC, DS CoC, or Lancia CoC (and in some cases other Stellantis-related marques), but the process and the data requirements are consistent: the goal is to produce the correct EU Certificate of Conformity for your exact VIN.
Quick takeaway: “Stellantis CoC” is shorthand. The CoC must match your vehicle’s brand + model + variant/version + VIN. That’s what registration authorities use to validate emissions, weights, and technical data.
Brands covered by Stellantis (CoC requests)
Below is a practical list of the most common Stellantis brands people request a COC certificate for. If your vehicle is one of these, you’re in the right place.
| Brand | Common searches | Typical registration use |
|---|---|---|
| Fiat | Fiat CoC, Fiat certificate of conformity, CoC Fiat by VIN | EU registration after import (Italy, Spain, France, Germany, etc.) |
| Peugeot | Peugeot CoC, Peugeot COC certificate, certificate of conformity Peugeot | Vehicle registration data verification (CO₂, weights, variant) |
| Citroën | Citroen CoC, Citroen certificate of conformity, COC Citroen EU | Cross-border registration; matching EU type-approval data |
| Opel | Opel CoC, Opel COC document, certificate of conformity Opel | Registration authorities requesting standardized EU specs |
| Jeep | Jeep CoC, Jeep certificate of conformity, COC Jeep Europe | Import/registration; correct emissions and mass data |
| Alfa Romeo | Alfa Romeo CoC, Alfa Romeo COC certificate, CoC Alfa by VIN | Registration and taxation (kW, CO₂, type approval) |
| DS Automobiles | DS CoC, DS certificate of conformity, DS COC document | Variant/version confirmation, especially for newer models |
| Lancia | Lancia CoC, Lancia certificate of conformity, CoC Lancia EU | Often requested for older registrations or cross-border imports |
Note: coverage depends on vehicle type-approval and data availability. The safest way to confirm is to check the VIN and the vehicle details.
Why models and variants matter (this is where most delays happen)
Two cars can look identical and still require different technical data for registration. That’s why registration offices care about variant/version—and why a Stellantis CoC request should never be “approximate”.
Common examples:
- Same model, different engine: changes power (kW), emissions, and sometimes weight.
- Same engine, different trim/market: tyre sizes, noise values, and equipment can vary.
- Hybrid vs petrol/diesel: different EU approval data and CO₂ fields.
- Commercial vs passenger versions: categories and mass limits may differ.
Avoid this: Requesting a “generic CoC” for your brand without providing the correct VIN. A single wrong character in the VIN can lead to delays or an unusable document for registration.
When you typically need a Stellantis CoC (real-life cases)
You’ll most commonly need a Certificate of Conformity when the vehicle is being registered in a country where its technical record isn’t already in the local system. This happens a lot with imports and cross-border purchases.
| Situation | What the authority needs | Why the CoC helps |
|---|---|---|
| Importing a used car (EU → EU) | Standardized technical data + EU approval reference | Speeds up registration and reduces manual checks |
| Registering a car previously registered abroad | Exact variant/version and emissions data | Prevents missing-field issues (CO₂, weights, kW) |
| Correcting incomplete database entries | Verified factory specs | Fixes mismatches that can block registration |
| Newer models with multiple variants | Precise configuration data | Avoids rejections due to wrong variant |
Fastest way to start: use the VIN
The VIN is the most reliable identifier for a COC certificate. If you have it, you can usually start right away.

How to request the right Stellantis CoC (without back-and-forth)
A smooth CoC request is not about “filling a form”. It’s about giving the exact information that allows a clean match to your vehicle’s type-approval record. Here’s the short checklist that saves days:
- VIN (17 characters): verify it twice (registration paper + VIN plate if possible).
- Registration document (if available): helps confirm the exact model and first registration details.
- Clear photos or scans: avoid blurry images and cut corners.
- Delivery details: your email and shipping address (if required by the selected format).
| Common error | What happens | Best fix |
|---|---|---|
| VIN typo (0/O, 1/I) | Record mismatch → delays | Copy/paste VIN + double-check against VIN plate |
| Unclear registration photos | Manual review needed | Upload a flat, well-lit photo; capture full document |
| Wrong assumption about brand | Request points to wrong channel | Use VIN to confirm brand/model before submitting |
| Choosing the wrong “document type” | Authority may reject it | Match what the registration office requested: “CoC / Certificate of Conformity” |
If you’re not sure whether you need a CoC or a technical data sheet, read: CoC vs Technical Data Sheet. It’s one of the fastest ways to avoid ordering the wrong document.
FAQ: Stellantis CoC (Brands, VIN, Registration)
Which brands are included in Stellantis for CoC requests?
The most common are Fiat, Peugeot, Citroën, Opel, Jeep, Alfa Romeo, DS Automobiles, and Lancia. The correct approach is always to confirm by VIN and match the vehicle’s exact type-approval record.
Is “Stellantis CoC” a single document for all brands?
No. “Stellantis CoC” is how people describe the request, but the actual Certificate of Conformity is tied to the specific brand and the vehicle’s type approval. Your CoC must match your VIN and variant/version.
Can I order a CoC certificate by VIN only?
In most cases, the VIN is the primary identifier. Depending on the case, you may also be asked for a registration document or proof of ownership, especially if data verification is needed for your vehicle’s variant.
Do I need a Fiat/Peugeot/Citroën/Opel CoC for registration in another EU country?
Often yes—especially for imports or cross-border registrations. Authorities use the CoC to verify standardized EU technical data (CO₂, weights, power, approvals). Requirements can vary, but having the correct CoC usually simplifies the process.
What is the biggest cause of CoC delays?
The #1 cause is an incorrect or mismatched VIN/model/variant. The #2 cause is unclear documents. If you want speed, verify the VIN carefully and upload clean scans.
What if my vehicle was imported from outside the EU/EEA?
Non-EU imports may require additional compliance steps. In those cases, a standard EU CoC may not be sufficient, and the registration office may request extra inspections or documentation.
