Verification of car license plates is a mandatory procedure when buying, selling, registering or restoring documents for a car. It confirms that the units and body parts correspond to the data in the PTS and have not been replaced illegally. But how exactly does this verification take place? Where is it carried out, what documents are needed and what to do if discrepancies are found?
In this article, we will analyze the entire reconciliation process step by step - from preparation to receipt of the protocol. We'll tell you what numbers are checked (VIN, body, engine, chassis), where to look for them on popular car models, and how to avoid common mistakes. Also, what to do if the numbers are broken or unreadable, and how this will affect registration with the traffic police.
What is number matching and why is it needed?
Number matching is a procedure for visually and technically comparing vehicle identification numbers with vehicle registration records. vehicle passport (PTS) and registration certificate (CTC). It is carried out to confirm the legality of the car and the absence of a criminal history (theft, change of license plates, replacement of units).
Without reconciliation it is impossible:
- 📝 Register the car with the traffic police (upon purchase, re-registration, restoration of documents).
- 🔄 Sell a car - the new owner will not be able to re-register it without checking it.
- 🔧 Restore PTS or STS if lost.
- 🚔 Remove the car from the wanted list (if it is listed in the stolen database).
Reconciliation is carried out in traffic police, MREO, accredited expert organizations or at notary (for transactions). The cost depends on the region: in 2026 on average from 500 to 2,000 rubles.
What numbers are checked during reconciliation?
When reconciling, be sure to check 4 room types:
- VIN code - a unique 17-digit vehicle identifier, which is duplicated on the body, chassis and, in some models, on the windshield.
- Body number - usually coincides with the VIN, but on older cars (before the 2000s) it may differ.
- Engine number — knocked out on the cylinder block, checked for compliance with the title.
- Chassis/frame number — relevant for trucks, SUVs and minibuses.
Where to look for numbers on popular models:
| Make/Model | VIN code | Engine number |
|---|---|---|
| VAZ 2107, 2110, Granta | Under the hood on the side member, on the floor under the driver's seat | On the cylinder block (on the left, closer to the cabin) |
| Toyota Camry, RAV4 | On the windshield (lower right), under the hood on the dashboard | On the engine block (front, under the plastic cover) |
| Volkswagen Polo, Golf | Under the rear seat (under the carpet), on the side member | On the cylinder block (rear, box side) |
| Hyundai Solaris, Kia Rio | On the windshield, under the hood on the mudguard amplifier | On the engine block (front, under the air duct) |
⚠️ Attention: On some cars (for example, Mercedes-Benz, BMW) the engine number may not be on the block - instead, they check the data from the nameplate under the hood. Check this in advance in the PTS!
Where numbers are verified: 4 official methods
Reconciliation can be done in several places - the choice depends on the purpose of the check and the urgency. Let's consider all the options:
1. Traffic police (MREO)
The most reliable and cheapest way is verification directly when registering the car. Cost: 500–800 rubles (included in the state fee for registration). Pros:
- ✅ The result is immediately entered into the traffic police database.
- ✅ No need to go to another place.
- ✅ Minimal risk of errors (checked by experienced employees).
Minus - long queues (in some regions, sign up 2-3 weeks in advance).
2. Accredited expert organizations
Private companies that are licensed to conduct reconciliations. Cost: 1,000–2,000 rubles. Suitable if you urgently need to check a car before purchasing or for a notary. Example organizations:
- 🔍 NIIAT (Research Institute of Automobile Transport).
- 🔍 Rosavtoekspertiza.
- 🔍 Local expert bureaus (check accreditation on the traffic police website).
3. Notary
When drawing up a purchase and sale agreement, the notary can verify the numbers (the cost is included in the service, ~1,500–3,000 rubles). This is convenient, but:
⚠️ Attention: The notary does not enter data into the traffic police database - reconciliation is only needed to confirm the transaction. To register a car, you still have to go to the MREO.
4. Online verification (preliminary)
Before going for reconciliation, you can check the numbers yourself through:
- 🌐 Official website of the traffic police (VIN check for theft and restrictions).
- 🌐 Services Autocode, CarVertical (paid car history).
❌ This will not replace a full reconciliation, but will help identify obvious inconsistencies in advance.

Step-by-step instructions: how reconciliation takes place at the traffic police
Let's look at the process using the example of reconciliation when registering a car with the MREO. The whole process takes from 30 minutes to 2 hours (excluding queue).
Step 1. Preparing documents
Before your trip, check:
- 📄 Owner’s passport (if you own the car) or power of attorney (if you are acting on his behalf).
- 📄 PTS - must be original, no corrections.
- 📄 STS (if the car is already registered).
- 🔑 Car keys - the inspector will open the hood and doors.
Step 2. Vehicle inspection
The inspector conducts a visual inspection:
- Checks body integrity (traces of welding, repainting, non-original parts).
- Checks VIN code in 3–4 places (on the body, chassis, under the hood).
- Reads engine number (uses a mirror or endoscope if necessary).
- Checks numbers on the windows (if any).
What to do if the engine number is not visible?
If the engine number is obscured by an attachment (such as a turbine or generator), the inspector may:
1. Ask to dismantle the interfering parts (at your own peril and risk).
2. Use an endoscope to examine hard-to-reach places.
3. As a last resort, refer to the PTS data, but this may raise questions during further registration.
Step 3. Drawing up a protocol
If everything is in order, the inspector fills out reconciliation protocol (form No. 1). It states:
- 📋 Make, model, year of production of the car.
- 📋 All verified numbers (VIN, body, engine).
- 📋 Notes (for example, “the engine number is not readable, the data is taken from the vehicle title”).
The protocol is signed by the inspector and the owner of the car. Without this document, registration will be suspended!
Step 4. Entering data into the database
Data from the protocol is entered into EAISTO (Unified automated information system for technical inspection). After this, the car can be registered or sold.
If the inspector finds discrepancies in the numbers, the car will be sent to forensic examination. This can take up to 30 days and cost from 5,000 rubles.
Common problems during reconciliation and how to solve them
Even honest owners may have difficulties with reconciliation. Let's look at typical cases and ways to eliminate them.
1. Numbers are not readable (corrosion, dirt, paint)
If the plates are painted over or rusted, the inspector may:
- 🔧Ask clear number with a soft brush or solvent (without damaging the metal!).
- 🔍 Use ultraviolet lamp to identify erased characters.
- 📝 Draw up an act of unreadability and take data from the PTS (but this may raise questions when selling).
2. The numbers do not match the PTS
Discrepancies occur due to:
- 🔨 Number interruptions (crime story).
- 🔧 Engine replacement (legal, but not reflected in the documents).
- 📝 Errors in PTS (typo when issuing).
What to do:
- If there is an error in the PTS, contact traffic police for correction (expertise will be required).
- If the engine was replaced legally, provide documents for a new unit (receipts, purchase and sale agreement).
- If tampering is suspected, the car will be sent to forensic examination.
3. Car after an accident with replacement of body parts
If the car was restored after an accident, questions may arise regarding:
- 🚗 Spars (if they are replaced, the VIN may be lost).
- 🚪 Doors (VIN is sometimes duplicated on them).
- 🔧 Wings, hood, trunk (if they are not original).
Solution:
- 📄 Provide documents for repairs (acts, receipts, before/after photos).
- 🔍 Pass examination to confirm that replacing parts does not hide the number interruption.
If you are buying a used car, ask the seller to get verified in advance - this will save your time and money. Pay attention to the reaction: if he refuses, this is a reason to be wary.

Is it possible to complete the verification yourself?
No, number matching is official procedurewhich is carried out only by authorized persons:
- 👮 Traffic police officers.
- 👨⚖️ Notaries (for transactions).
- 👷 Experts from accredited organizations.
However you can prepare for reconciliation yourself:
- Check the license plates on the car and check with the PTS in advance.
- Clean the numbers from dirt and rust (without damaging the metal!).
- If you have doubts about the legality of the car, order paid history check (for example, via Autocode).
❌ Don't try:
- 🔨 “Restore” erased numbers yourself (this qualifies as a fake).
- 📝 Forge a reconciliation protocol (this is a criminal offense under Article 327 of the Criminal Code of the Russian Federation).
- 🚗 Hide the facts of replacing the engine or body parts (it is better to legalize them in advance).
FAQ: Frequently asked questions about number matching
Is it possible to sell a car without checking the license plates?
Technically yes, but the new owner will not be able to register it. Therefore, reconciliation is mandatory for any transaction. An exception is sales for spare parts (with a note in the contract).
What to do if the engine number does not match the title?
If the engine was replaced legally, provide documents for the new unit (receipts, sales contract). If the reason is a PTS error, contact the traffic police for correction. If tampering is suspected, the car will be sent for examination.
How long is the reconciliation protocol valid?
The reconciliation protocol does not have an expiration date, but when registering a car with the traffic police, it must be relevant (usually no older than 1–3 months). If a lot of time has passed since the verification or the car has been modified, a new check may be required.
Can they refuse verification if the car is tinted?
Yes, if the tinting does not comply with GOST (light transmission less than 70% on the windshield). The inspector may require the film to be removed to check the VIN on the glass. It is better to remove the tint in advance or have it with you certificate of conformity.
Is reconciliation necessary when restoring a vehicle title?
Yes, definitely. If you lose your PTS, you will have to undergo a plate verification to confirm that the car is not stolen and does not have a criminal history. Only after this the traffic police will issue a duplicate.
