You’ve bought a car (or you’re about to) and you need a Certificate of Conformity. The first question most people ask is simple: how long will it take? The honest answer is: it depends. But the variables are predictable, and once you understand them, you can plan accordingly and avoid the most common delays.
This article walks you through the full COC timeline, from the moment you place an order to the moment the document is in your hands, and explains exactly what affects processing speed for each vehicle brand.
There are two delivery paths for a COC through Auto-COC.eu, and the difference in timing is significant:
Regardless of which delivery option you choose, Auto-COC.eu sends a DIGITAL PDF COPY OF YOUR COCas soon as the document is processed. Many registration authorities in EU countries accept the PDF for the initial registration steps, meaning you don’t necessarily have to wait for the physical document to arrive before you can begin the process.
Here is what happens between placing your order and holding the certificate in your hands. Understanding each stage helps you set realistic expectations — and spot where things might slow down.
The single biggest variable in COC processing time is the vehicle manufacturer. Different brands have different systems, response times, and administrative processes. Here are all the factors that play a role:
The table below gives a general indication of typical processing times at the manufacturer stage for the most popular brands. These are averages — individual orders may be faster or slower depending on the factors above.
If you’re working towards a registration deadline, there are concrete steps you can take to minimise waiting time at every stage of the process.
The fastest single thing you can do is get the VIN right first time. A wrong VIN means a delay while the error is identified and corrected. Verify it on the dashboard, door jamb, and registration document — all three should match.
For just €19.90 extra, your certificate ships via FedEx or UPS rather than standard post. On standard shipping, a 3-day processing time can easily become a 10-day total wait once postal transit is included. Express shipping dramatically compresses the delivery leg of the timeline.
Orders placed early in the working week are processed and dispatched faster. An order placed Thursday afternoon, for example, may sit in the queue over the weekend even if processing is quick, effectively adding 2 days to your wait.
The moment your COC is processed, you’ll receive a digital PDF by email. Many EU registration authorities accept this for initial submission while the physical original is in transit. Check with your local registration office — this alone can save you days.

This can happen if the VIN was entered incorrectly, or in rare cases where a vehicle’s records are stored under a slightly different identifier in the manufacturer’s system (common with some older or imported models). Auto-COC.eu will contact you to resolve the discrepancy.
Vehicles built to specification for a specific market (fleet contracts, diplomatic vehicles, special editions) occasionally require manual verification. This is uncommon but can add 1–3 business days.
Like any business system, manufacturer databases occasionally experience maintenance windows or unusually high request volumes — typically around end-of-year periods or after major product launches. These delays are outside anyone’s control, but Auto-COC.eu monitors them and will notify you if your order is affected.
For most people ordering a COC through Auto-COC.eu, the realistic total timeline from order to physical document in hand is 5–8 business days for standard delivery, or 4–6 business days with express. If you need to begin registration before the physical document arrives, the digital PDF sent upon processing gives you a head start.
The two things most within your control are: getting the VIN right first time, and choosing express delivery if timing is at all tight. Everything else is largely determined by the vehicle manufacturer — and Auto-COC.eu handles that part for you.
Enter your VIN, select your brand, and choose standard or express delivery.
