Where to look for a car's registration number: a detailed guide with photos and nuances

You bought a used car, are taking out insurance or are preparing to sell, but can’t find registration number? This problem is familiar to many car owners - especially those who are encountering car documents for the first time. Technical passport (or, more precisely, Vehicle passport - PTS) contains critical information, but its number is often confused with other codes from the STS, the sales contract, or even the VIN code of the car.

In this article we will look at all possible places, where the registration number may be indicated, we will explain the difference between PTS and STS, and show how not to confuse it with other details. You will also learn what to do if the document is lost or the number is erased - after all, without this data it is impossible to complete a transaction, register the car or get a duplicate.

Spoiler: registration number never matches the STS number or VIN code, and finding it takes no more than a minute if you know where to look. Let's start with the main thing - where exactly to look for this number in the documents.

1. Where to look for the registration number in the PTS: step-by-step instructions with photos

The main document where the registration number is written is the Vehicle Passport (PVC). It is issued upon production of the car or upon first registration with the traffic police. Externally, the PTS looks like an A5 book with a blue cover (until 2020) or pink (new sample).

The registration number in the PTS is indicated in two places:

• 📌 Title page (first page) - in the upper right corner under the inscription “Series and number”. Format: XX XX 123456 (two letters, space, two numbers, space, six numbers).
• 📌 Owner details page — in the “Vehicle Information” table in the “Vehicle Passport Number” column.

Example for PTS old style (until 2020):

Document field	Example value	Where is
PTS series and number	77 TR 123456	Title page, upper right corner
VIN code	XTA211230D1234567	Table “Information about the vehicle”, column 3
Engine number	12345678	Table “Information about the vehicle”, column 5

⚠️ Attention: If your PTS number is indicated in the format XX 123456 (without the second pair of digits), this is outdated format — such documents were issued until 2010. They are still in effect, but when registering transactions they may raise questions from a notary or the traffic police.

2. How does the PTS number differ from the STS number - and why are they confused?

The most common mistake is to confuse the number technical passport (PTS) with number registration certificate (CTC). These documents perform different functions:

• 📄 PTS - confirms technical specifications car (model, color, engine power) and ownership history.
• 🚗 STS - confirms right to manage a specific car (issued to the owner).

STS number is indicated in upper right corner plastic card (format: 12 34 567890). It is often asked to be presented when registering fines or insurance, but for purchase and sale transactions it has no legal force — you need the PTS number.

How to distinguish them visually:

Parameter	PTS	STS
Format	Book A5	Plastic card
Color	Blue/pink	Pink (until 2023) or blue (new)
Where is it issued?	Factory or traffic police during the first registration	Traffic police upon registration
The number is needed for	Transactions, registration, duplicate	Fines, insurance, technical inspection

3. Where else can you find the registration number (if the PTS is lost)

If the original PTS is lost or is in the possession of the previous owner, the registration number can be recovered from other sources. Here 5 alternative locations, where it can be specified:

1. Sales and purchase agreement (PSA) — in the “Vehicle Data” section, the series and PTS number are usually duplicated. Look for the line “Vehicle Passport No.”
2. OSAGO/CASCO insurance policy — in some policies (especially old ones) the PTS number was written in the “Documents for the vehicle” column.
3. Technical certificate (if available) - in Soviet cars or foreign cars before the 2000s, the PTS number was sometimes duplicated on the coupon.
4. Electronic database of the traffic police — if the car is registered with you, the PTS number can be found through official website of the traffic police (section “Vehicle check”).
5. Archival copies of documents — check photographs or scans that may have been left in the mail, in cloud storage, or with the previous owner.

⚠️ Attention: If the PTS number cannot be found in any of the sources, and the original document is lost, you will have to issue a duplicate. To do this, contact the traffic police with an application, passport and STS. The cost of a duplicate in 2026 is: 800 rubles (state duty).

4. How not to confuse the PTS number with the VIN code and other codes

There are many alphanumeric combinations found in car documents, and all of them different in purpose. Here's how to tell them apart:

• 🔢 PTS number — XX XX 123456 (series + number). Needed for transactions and registration.
• 🚘 VIN code — XTA211230D1234567 (17 characters). A unique vehicle identifier stamped on the body.
• 📋 STS number — 12 34 567890. Needed to control the car.
• 🔧 Engine number — 12345678. Indicated on the vehicle title and on the engine block.
• 🔖 Chassis/frame number — ABC123456789. Relevant for trucks and motorcycles.

Main rule: PTS number always contains letters and spaces, and the VIN code is only numbers and Latin letters no spaces. If you were sent a photo of a document with a request to “pass over the registration number”, and there are only 17 characters, this is 100% VIN, not PTS.

An example of real confusion:

"The client sent a photo of the vehicle title and asked: 'Is this the registration number? XTA211230D1234567.' In fact, this is a VIN code, and the PTS number was indicated above - 77 TR 123456.»

What happens if you specify VIN instead of PTS number?

When completing a transaction, a notary or the traffic police will refuse registration, since the VIN is not a document requisite. At best, you will be asked to correct the mistake; at worst, you will be suspected of fraud and sent to have your car checked.

5. Registration certificate number in the electronic PTS - where to look in 2026

Since 2020, it has been operating in Russia electronic PTS (EPTS) — a digital analogue of a paper document. Its number has the same format (XX XX 123456), but you can only find it in personal account on the traffic police website or through the Gosuslugi Auto mobile application.

How to check the EPTS number:

1. Login to traffic police.rf or in the “State Services Auto” application.
2. Go to the "My Vehicles" section.
3. Select a car - the EPTS number will be in the “Documents” block called “Vehicle Passport”.

⚠️ Attention: If you are buying a car with an EPTS, make sure that the seller has provided access to the electronic document via Public services. Without this, you will not be able to confirm the authenticity of the number and complete the transaction.

Advantages of EPTS:

• ✅ You cannot lose or spoil it.
• ✅ All changes (change of owner, body color) are made automatically.
• ✅ Available 24/7 via the Internet.

Disadvantages:

• ❌ Internet access required for verification.
• ❌ Not all banks and insurance companies accept EPTS (check in advance).

6. What to do if the PTS number is erased or unreadable

If the number on the paper PTS is erased, smeared or unreadable due to damage, there is 3 legal ways restore it:

1. Contact the traffic police — present your passport and STS, write an application for a duplicate. Production time - up to 30 days.
2. Request data through State Services — in the “Transport and Driving” section you can request an extract from the vehicle register, where the PTS number will be indicated.
3. Contact previous owner - if the purchase was recent, he might still have copies of the documents.

⚠️ Attention: If the number is erased intentionally (for example, corrected or painted over), such a PTS is considered void. The use of a damaged document is equated to forgery and is punishable under Art. 327 of the Criminal Code of the Russian Federation (fine up to 80,000 rubles or correctional labor).

Case study:

“The client brought a PTS, where the number was covered with a proofreader. It turned out that the car was listed as stolen, and they tried to fake the license plate. The deal had to be canceled and the buyer lost his deposit.”

7. Common mistakes when specifying the PTS number - and how to avoid them

Even experienced car owners sometimes make mistakes when working with the registration number. Here TOP-5 misses and how not to repeat them:

• 🔤 Confused series and number - for example, they write 77TR123456 instead of 77 TR 123456 (no spaces). This is critical for paperwork!
• 📱 The number is transmitted over the phone with distortions - the letters “T” and “P”, “B” and “8” sound the same. Always clarify: “T is like Tango, P is like Dad.”
• 🖨️ Copying a number from a bad scan — if the document is scanned unclearly, the numbers “6” and “8”, “1” and “7” can be confused.
• 📅 Use the old PTS number — when a document is replaced (for example, when a last name is changed), the number changes!
• 🚔 They don't check the number before the transaction - Fraudsters falsify the PTS, and the license plate may belong to another car.

How to avoid problems:

1. Always double check the number according to the original PTS, not a copy.
2. When transferring data duplicate with voice and text (for example, in messenger).
3. Before the deal check the PTS number through the Autocode service or traffic police - it must match the VIN code of the car.
