Every driver has encountered the abbreviation at least once. INAD on road signs, maps or in navigators, but not everyone understands what it means and why it is needed. Highway Identification Number (INAD) is a unique code that is assigned to each federal, regional or local highway in Russia. It serves not only for orientation, but also for legal accounting, planning repairs, and even calculating tolls for trucks using the Plato system.

Unlike the usual names like “Leningradskoye Highway” or “Route M4”, the INAD number is standardized and is used in official documents, for example, in transportation contracts, accident inspection reports or when issuing permits for the transportation of dangerous goods. Knowing this number helps to avoid confusion - after all, the same road can have several “folk” names in different regions. And for logistics companies and forwarders, INAD generally becomes the key to optimizing routes and calculating costs.

But how exactly is this number formed? Where can I find it if it is not indicated on the signs? And why sometimes on Google or Yandex maps the road number does not match what is written on the poles? We will understand all the nuances - from the code structure to practical application in 2026.

What is a Highway Identification Number (HIN) and why is it needed?

A highway identification number is not just a set of numbers and letters, but a part state road network accounting system. It is assigned according to Order of the Ministry of Transport of Russia No. 15 of January 17, 2007 (last modified 2023) and serves for:

  • 📍 Orientation — quickly determine which road is meant, even if it has several names (for example, M10 "Russia" and E30 - this is the same route).
  • 📑 Legal registration — in contracts, road accident reports, and permits for the transportation of goods, it is INAD that is indicated, and not “just the highway to St. Petersburg.”
  • 💰 Fee calculation — the Platon system for trucks >12 tons charges travel on specific road numbers.
  • 🛠️ Repair planning - budget funds are allocated for specific INADs, and not abstract “sites”.

Without this number it is impossible, for example, to obtain a transportation permit large cargo or prove in court that the accident occurred on a federal highway and not on a municipal road. And for truck drivers, knowledge of INAD helps to avoid fines: if the route in the navigator is laid out along a road with restrictions for trucks (for example, A103 in the Moscow region), but the number has not been verified - there is a risk of receiving a “letter of happiness” for driving through a restricted area.

Interestingly, INAD is assigned not only to asphalt highways, but also dirt roads, if they are included in the register. But temporary bypass routes or private entrances to enterprises do not receive such a number.

ID number structure: how to decipher letters and numbers

The road number consists of 3 parts, each of which carries specific information:

  1. Prefix (letter) - indicates importance of the road:
    • 🅰️ A — motorway (for example, A113 - Moscow Small Ring).
    • 🅼️ M — federal road (for example, M4 "Don").
    • 🅿️ P — regional (for example, P21 "Cola").
    • 🅺️ K — local (municipal) (for example, K-178 in the Leningrad region).
  • Main number (1–3 digits) — ordinal identifier within a category.
  • Suffix (optional) - letters or numbers after the hyphen, indicating branches (for example, M7-1 — exit from the highway M7 "Volga").

    • Decryption examples:

    • 🔹 M1 "Belarus" - federal road No. 1 (Moscow - Minsk).
    • 🔹 P239 - regional road No. 239 (Yaroslavl - Rybinsk).
    • 🔹 A118 — highway No. 118 (TsKAD-3 in the Moscow region).
    • 🔹 K-407-1-1 - a municipal road in the Tver region with two branches.

    Important: numbers with the letter “E” (for example, E30) are European routes that can pass along several Russian roads with different INADs. For example, E30 in Russia coincides with M10, A10 and other sections.

    Why can one road have several numbers?

    Sometimes a highway changes status (for example, a regional road becomes a federal road) and is assigned a new INAD, but the old numbers can remain on the signs for years. Also, several routes may intersect on one physical section - for example, M4 and E115 at the entrance to Rostov-on-Don. In such cases, all current numbers are indicated on the signs, separated by commas.

    Where to look up the road identification number: 5 proven ways

    If the number is not indicated on road signs (and this often happens), you can find it in the following ways:

    1. Official maps of Rosavtodor

    On the website Rosavtodor yes interactive map of federal roads, where when you click on a route, its INAD, length and responsible management are shown. For regional roads, similar maps are published by local departments of transportation.

    2. Yandex.Maps and Google Maps

    In mobile versions of applications:

    • 📱 B Yandex.Maps: tap on the road → “Details” → “Number” field.
    • 📱 B Google Maps: click on a route → sometimes the number is shown in the description (but not for all roads).

    Important: these services are not always up-to-date - for example, a new section of the Central Ring Road may be listed under an old number.

    3. Road signs

    INAD is indicated on:

    • 🟢 Green signs 6.14.1 “Route number” (white numbers on a green background).
    • 🟡 Yellow signs for toll roads (for example, M11 "Neva").
    • 🔵 Blue signs under direction signs (for example, M4 → Rostov-on-Don).

    4. Documents for the car or cargo

    If you are transporting cargo, the INAD may be indicated:

    • 📄 B transportation permit (for dangerous or bulky cargo).
    • 📄 B waybill (if the route is agreed with the logistics operator).
    • 📄 B road accident report (if the accident occurred on the highway).

    5. Databases of transport companies

    Services like "Plato" or "TransConsulting" have their own registers of roads with INAD, current tariffs and restrictions.

    Specify the route in the navigator

    Check the number on the Rosavtodor map

    Check current restrictions for trucks (if you are driving a truck)

    Take photographs of road signs with numbers in case of disputes

    INAD and the Platon system: why the road number affects the fare

    Since 2015, all trucks weighing >12 tons are required to pay tolls on federal highways through the system "Plato". The tariff depends on:

    • 💵 Road categories (for example, according to M4 the fee is higher than P21).
    • 📏 Length of the section (determined by INAD).
    • 🚛 Vehicle type (number of axes).

    Example of tariffs for 2026 (according to platon.ru):

    Road category INAD example Cost per 1 km, ₽
    Motorway (A) A113, A107 4.67
    Federal (M) M1, M4 3.73
    Regional (P) P21, P23 2.12
    Municipal (K) K-178, K-407 0.00 (not taxed)
    ⚠️ Attention: If the route contains an incorrect INAD (for example, instead of M4 a path was laid along a parallel regional road P22), the Plato system may calculate a lower fee. But when checked, this is regarded as payment evasion - fine up to 5000 ₽ under Art. 12.21.3 Code of Administrative Offences.

    To avoid errors:

    1. Check INAD for Rosavtodor map.
    2. Use official Plato calculator to calculate the cost.
    3. Check your route with current restrictions (for example, on M11 special rates apply for tall trucks).
    💡

    If you are driving on an unknown road, take a screenshot of the INAD from your navigator and save it in case of disputes with inspectors or the Platon operator.

    Even experienced drivers and logisticians sometimes confuse road numbers, which leads to problems. Let's consider typical situations:

    1. Confusion with European routes (E)

    Number E30 - this is not INAD, but international route, which in Russia passes through:

    • M10 (Moscow - Tver),
    • A111 (bypass of Tver),
    • M9 (to the border with Belarus).

    If the contract specifies only E30, but in fact the cargo was transported along P92, this may be grounds for termination of the contract.

    2. Outdated numbers on old signs

    Example: track M7 "Volga" after reconstruction received new plots with numbers M7-1, M7-2, but on some signs it still hangs simply M7. If the accident report contains an outdated number, this may complicate the analysis with the insurance company.

    3. Errors in navigators

    B Google Maps or Yandex.Navigator Sometimes unofficial numbers are displayed. For example, Western speed diameter in St. Petersburg may appear as A118 (correct) or simply “WHSD” (incorrect for documents).

    ⚠️ Attention: If an incorrect INAD is indicated on the waybill or transportation permit, and this is discovered at the weight control post, the cargo may be detained until the discrepancy is eliminated. According to FAS statistics, 12% of truck delays in 2023 were due to errors in road numbers.

    To avoid problems:

    • 🔍 Always check your INAD with official card of Rosavtodor.
    • 📋 Please indicate in your documents all current numbers (for example, M4 / E115).
    • 📱 Use professional navigators for truckers (for example, "Navitel Trucker" or «Wialon»), where road numbers are updated more frequently.

    INAD in judicial practice: when the road number becomes evidence

    The road number often becomes a key argument in disputes:

    • 🚔 Accident on the federal highway - if the accident occurred on M1, and not on a parallel regional road, this affects the jurisdiction (federal or regional court) and the amount of compensation.
    • 🚛 Transportation of dangerous goods — permission is issued for a specific INAD. If the cargo was transported along another road, this is a violation of licensing requirements.
    • 💸 Disputes with "Plato" — if the system has calculated the fee using the wrong number, INAD will help you challenge the receipt.

    Case study:

    In 2022, a logistics company challenged a fine for non-payment of tolls. M11, presenting data from the on-board recorder, where the route along a parallel road was recorded P104. The court sided with the carrier, since the INAD in Plato’s receipt did not coincide with the actual route.

    To use INAD as evidence:

    1. Take a photo road signs with number.
    2. Save screenshots from the navigator with reference to time.
    3. Request extract from Rosavtodor (possible through State Services).
    💡

    INAD is not just a number, but a legally significant identifier. In controversial situations, its presence in documents can become a decisive factor.

    The future of INAD: what will change in 2026–2026

    Launched in Russia in 2026 road accounting reform, which will also affect identification numbers:

    • 🆕 Digitalization — all INADs will be linked to Unified digital road map (ETSKD), which will eliminate discrepancies between signs and navigators.
    • 🔄 Re-certification of roads — some regional highways (for example, approaches to airports) will become federal and will receive new numbers.
    • 💳 Expansion of "Plato" — from 2026 the system may extend to roads of the category R (currently the fee is only charged for M and A).

    It is also planned to introduce QR codes on road signs, through which you can immediately obtain information about the road, including INAD, restrictions and current repairs.

    For drivers and companies this means:

    • ✅ More transparency - all road data will be publicly available.
    • ⚠️ More responsibility - mistakes in INAD will be more difficult to challenge.
    • 💰 Possible increase in Platon tariffs for travel on updated roads.

    FAQ: Answers to frequently asked questions about road identification numbers

    🔹 How to find out INAD if there are no signs on the road?

    Use official sources:

    1. Rosavtodor map: rosavtodor.ru/road-map.
    2. Regional GIS (for example, "Roads of the Moscow region").
    3. Mobile applications "Roads of Russia" or "Avtodor".

    If the road is not listed in the register, it means that it does not have an INAD (for example, private or temporary).

    🔹 Can one road have several INADs?

    Yes, if:

    • The road passes through several regions (for example, M5 changes the number to P239 in some areas).
    • The route is part European route (for example, E30 = M10 + A111).
    • Happened reorganization (for example, after reconstruction, the old number remains on the signs, and the new one remains in the documents).

    In such cases, all current numbers are indicated on the signs, separated by commas.

    🔹 Is it necessary to indicate INAD on the waybill?

    The legislation does not require the mandatory indication of INAD in waybills, but:

    • For cargo transportation (especially dangerous or large) road number recommended prescribe to avoid disputes.
    • If the route goes along toll roads (for example, M11), INAD will help confirm payment.
    • When Road accident the presence of INAD in the waybill simplifies registration.
    🔹 How to challenge a Platon fine if the road number is indicated incorrectly?

    Procedure:

    1. Collect evidence:
      • Screenshots from the navigator with INAD.
      • Photos of road signs.
      • Extract from Rosavtodor (request via Public services).
  • Write a complaint to Plato demanding a recalculation of the fee.
  • If you are not satisfied with the answer, please contact FAS or court.

    • Dispute period - 10 days from the moment of receipt of the receipt.

    🔹 Where can I find the current list of INAD for cargo transportation?

    Official sources:

    For international shipments, check the numbers on the website UNECE (European routes E).
