Since October 2005 the vehicle registration (Fahrzeugschein) has officially been the Zulassungsbescheinigung Teil 1 (registration certificate part 1) — both terms mean the same document. It proves that a vehicle is approved for road use and must be carried on every trip. The vehicle registration lists the central vehicle data: keeper, licence plate, date of first registration, vehicle identification number (VIN), make and model, key technical data such as power output and displacement, the pollutant class, and the due date of the next roadworthiness test (HU). When buying a used car it is the first source of facts: it shows the first registration, the number of previous keepers and when the HU is due, and can be cross-checked point by point against the vehicle. Important: the registered keeper is not automatically the owner — ownership is only proven via the Zulassungsbescheinigung Teil 2 (formerly the Fahrzeugbrief).
The vehicle registration: reading the Zulassungsbescheinigung Teil 1 correctly
The vehicle registration is the document that must always travel in the car — and when buying a used car it is the first hard source of facts. Anyone who knows what is listed on it can tell within minutes whether vehicle and paperwork match, when the car was first registered, and when the next roadworthiness test (HU) is due. This overview shows you what the Zulassungsbescheinigung Teil 1 (registration certificate part 1) is for and what a buyer needs to watch out for.
What the vehicle registration is and what you need it for
The vehicle registration is the document that proves a vehicle's current registration. Since 1 October 2005 it has officially been called the Zulassungsbescheinigung Teil 1 (registration certificate part 1). For Google and in everyday practice the two names mean one and the same thing: anyone searching for "Fahrzeugschein" means the Zulassungsbescheinigung Teil 1, and vice versa. Older documents from before 2005 still carry the old name but remain valid — you do not have to exchange them as long as nothing about the vehicle data changes.
The practical purpose is simple: the vehicle registration confirms that this exact vehicle, with this exact licence plate, is approved for use on public roads. That is why you must carry it on every trip and show it to the police on request. It belongs in the vehicle — unlike the second document, which you should keep at home. If the registration is missing during a check, you face a fine; and if it is lost, it is not simply replaced but has to be reapplied for at the registration office (Zulassungsstelle).
But for you as a used-car buyer, the vehicle registration is far more than a mandatory document. It is the first orderly set of data about the vehicle that you get to hold in your hands — before you have even started the engine or taken the first drive. Anyone who can read it can tell within a few minutes whether the seller's claims match the actual state of the paperwork. That is exactly why it pays to know its layout, rather than merely skimming the document.
Fahrzeugschein or Fahrzeugbrief? The difference in brief
A vehicle comes with two documents that are easily confused. The Fahrzeugschein — the Zulassungsbescheinigung Teil 1 (registration certificate part 1) — travels in the car and proves the registration. The Fahrzeugbrief — the Zulassungsbescheinigung Teil 2 (registration certificate part 2) — stays at home and documents the vehicle's history and ownership. Together the two form the complete set of documents that must be handed over in a sale.
The decisive difference concerns the question of ownership. The keeper entered on the vehicle registration is the person the vehicle is registered to — which is not necessarily the person who owns it. Keeper and owner can differ, for example with leasing, financing, or when a family member merely uses the car. Who really owns it, and may therefore sell it in a legally binding way, follows from the Zulassungsbescheinigung Teil 2, not from the vehicle registration.
For this overview, that distinction is enough. The ownership question in detail — who may sell, what the chain of previous owners means and what to watch for on part 2 — we cover in the dedicated article on the Zulassungsbescheinigung Teil 2. Here, just remember the principle: the vehicle registration tells you who drives the car; the Fahrzeugbrief tells you who owns it.
What is listed at the top
The vehicle registration is a DIN A6-sized document with a fixed grid of fields, each marked with a letter or a letter-and-number combination. These codes are uniform across Europe, so that a field can be identified unambiguously regardless of language. Instead of a diagram, a short overview of the fields that actually matter when buying a used car will help you get started.
| Field | Meaning | Why it matters when buying |
|---|---|---|
| C | Keeper's details (name, address) | Who is entered — cross-check against the seller's ID |
| B | Date of first registration | The "real" age of the vehicle |
| I | Date of registration to the current keeper | How long the current keeper has been driving the car |
| E | Vehicle identification number (VIN) | Unique identifier, must match the VIN on the vehicle |
| A | Licence plate | Must match the plates fitted |
| D.1 / D.2 / D.3 | Make, type, commercial designation | Is it really the model on offer |
| P.1–P.4 | Displacement, power output, fuel type | The engine's key technical data |
| V.9 / 14.1 | Emissions class / pollutant class code | Environmental sticker, driving bans |
This table is deliberately kept brief. It is meant to give you the layout, not to explain every field exhaustively. You will find the complete field-by-field legend with all the codes, the conversions and the key numbers (Schlüsselnummern) in our detail article on the field legend. It also explains how to convert the power output in field P.2 from kilowatts to metric horsepower (PS) and exactly where the displacement is shown.
A note by way of addition: the four main areas — keeper's details, vehicle identity, technical data and inspection dates — follow a logic. At the top and on the left are the details of who drives the vehicle and which vehicle it is. Further down and to the right come the engine's technical figures and the data on emissions and weights. Once you have internalised the rough grid, you will quickly find each field again, no matter which vehicle is in front of you.
What really matters when buying a used car
Not every field is equally important when buying. A few pieces of information, however, decide whether the offer is sound or whether you should look more closely. These are the fields you should check first on every vehicle.
The date of first registration (field B) is the actual age of the vehicle — not the year of manufacture. The two can differ: a vehicle built at the end of one year but only registered the following year is younger on paper than its build state suggests. For valuation, service intervals and expected wear, the first registration is the decisive anchor. We go deeper into the fine distinction between year of manufacture and first registration in the separate article on the subject.
The number of previous keepers is an important plausibility check. The vehicle registration itself does not contain a running count of all previous owners — that history follows from the Zulassungsbescheinigung Teil 2. What the vehicle registration shows, via field I, is the date since when the current keeper has been driving the vehicle. A very short keeping period combined with high pressure to sell is no proof of a problem, but it is a reason to ask specifically why. The HU date — the month of the next roadworthiness test (Hauptuntersuchung) — is also relevant to the buyer: if the HU is due soon, you either negotiate the price or have it done before the purchase, because a fresh sticker without an inspection report says little about the real condition.
Two details deserve special attention because they are often misunderstood. First: the keeper is not the owner. Never buy a vehicle on the basis of the registration alone, without having seen the Zulassungsbescheinigung Teil 2 — only it proves who may sell. Second: the key technical data (field P for the engine, plus the weight figures) must match the vehicle and your intended use. Anyone who wants to tow a trailer will find the permitted trailer load in the weight fields — which we cover separately in the article on weights, unladen weight and payload. The engine code letters, the chassis number and the pollutant class each have their own detail pages, because more hangs on them than an overview page can capture.
How to compare the paperwork against the vehicle
The vehicle registration only reveals its value once you compare the details on the paper with the real vehicle. This comparison takes a few minutes and uncovers a large share of the serious problems before they become yours. Deliberately take the time for it before you talk about price.
The most important comparison is the chassis number. The VIN in field E must match exactly the number stamped on the vehicle — usually visible on the vehicle floor in the engine bay, on the B-pillar, or behind a viewing window in the windscreen. Compare character by character, not just the beginning. Where exactly the VIN is located on the vehicle is explained in the dedicated article on the subject. Next, check the licence plate (field A) against the plates fitted and the vehicle data (make, type, fuel type) against what is actually in front of you. A diesel model on the registration but a petrol car in reality is not a detail — it is an alarm.
Finally comes the plausibility check: do the first registration, mileage and visual condition fit together? A twenty-year-old vehicle with supposedly very low mileage but a heavily worn steering wheel, seat and pedal rubbers tells a contradictory story. The vehicle registration supplies the hard figures against which you cross-check the softer impressions. To judge the mileage itself and the question of whether the odometer has been tampered with, you additionally need evidence such as a service booklet and invoices — the vehicle registration alone is not enough for that.
Warning signs around the paperwork
Some anomalies should put you on alert. They do not always mean fraud, but they call for an explanation before you go any further. Anyone who is too generous in overlooking discrepancies here risks, in the worst case, buying a vehicle without a clean origin.
Discrepancies between the paperwork and the vehicle are the clearest signal. If the VIN does not match, the licence plate does not fit, or the make, model or engine differs, break off the purchase for now and clarify the cause. Pay particular attention to numbers that have been altered or re-stamped on the vehicle: rough stampings, uneven spacing between characters, fresh paint or weld marks in the area of the VIN, or a VIN sticker that looks replaced. Such tampering points to stolen vehicles or cars assembled from several others.
Missing or incomplete documents are another warning sign. If the seller produces only the vehicle registration but not the Zulassungsbescheinigung Teil 2, they cannot prove ownership — and you cannot be sure whether they are even allowed to sell. Excuses like "the Brief is still with the bank" or "I'll send it on later" are a legitimate reason to postpone the purchase until all documents are complete. You should also be wary if the keeper's details on the registration do not match the ID of the person in front of you, without a traceable power of attorney to explain it.
One final point: conspicuously fresh-looking documents on an old vehicle also warrant a question. A newly issued vehicle registration can have entirely harmless reasons — loss, a move, a change of name. But it can also be a sign that an incriminating history was meant to disappear from the visible paperwork. Ask why the document is new, and cross-check the issue date against the rest of the vehicle's history.
When an independent look pays off
Reading the vehicle registration yourself is not rocket science — with this overview and the linked detail articles you will get a long way. The limits lie elsewhere: whether a re-stamped number really is tampering, whether an accident repair affects the vehicle's identity, or whether the technical data on the registration match the traces on the vehicle can be judged far more reliably with a trained eye. This is exactly where an independent look becomes valuable.
