The Russian ИНН
Russia charges VAT — НДС — and issues no separate VAT number for it. The number on an invoice is the ИНН, the taxpayer identification number the Federal Tax Service gives every company and every person, usually written with a second number, the КПП, beside it.
Format: RU + 10 digits (company) or 12 digits (sole trader)
Example: RU7451269247
Issued by: the Federal Tax Service (ФНС России).
The format
The ИНН has two lengths, and the length says what kind of taxpayer it is:
- 10 digitsA legal person — a company. The first four are the tax office that issued it, the next five a serial number, the last a check digit.
- 12 digitsA natural person, which includes an individual entrepreneur (ИП) trading under their own name. Four digits of tax office, six of serial number, then two check digits.
The check is a modulus 11 over the digits in front of it, weighted 2,4,10,3,5,9,4,6,8 for a ten-digit number, with the remainder taken modulo 10 so that it is always a single digit. A twelve-digit number runs the same rule twice, once for each of its two check digits. Vatlas applies it before any lookup, so a mistyped ИНН is caught without a network call.
ИНН, КПП and ОГРН — three numbers, one company
A Russian invoice usually shows two numbers separated by a slash, and a third one appears in the register. They are not interchangeable:
- ИННThe taxpayer. One per company, for its whole life, and the key everything else is found by.
- КППNine digits saying why that taxpayer is registered at a given tax office. A company with branches has one ИНН and several КПП, one per place it is registered — so a КПП identifies an establishment, never a company.
- ОГРНThirteen digits, the number the state register files the company under (fifteen — ОГРНИП — for an individual entrepreneur). Vatlas returns it as
nationalId.
There is no separate VAT registration number to look for: a Russian company either applies the general tax regime and charges НДС, or is on a simplified regime (УСН) and does not, and either way its ИНН is unchanged.
Finding the company behind the number
What the ФНС publishes for free
The full register of legal entities — the ЕГРЮЛ, which holds every Russian company with its complete address, directors and share capital — is sold, not published: the ФНС licenses it as XML archives for 150,000 ₽ a year, there is no free bulk copy, and egrul.nalog.ru answers one ИНН at a time from behind a captcha.
What is free, monthly and reachable by the number on an invoice is the unified register of small and medium-sized businesses (Единый реестр субъектов МСП). It is what Vatlas imports — a 2.1 GB archive a month, with every monthly edition since the register opened still online, so an answer can be dated rather than merely current.
What that register does and does not contain
It contains the full legal name — which in Russian spells the legal form out in front of it, «ОБЩЕСТВО С ОГРАНИЧЕННОЙ ОТВЕТСТВЕННОСТЬЮ …» — the ОГРН, the date the company entered the register, and where it is: town, district and region.
It does not contain large companies. The register is, by definition, of small and medium-sized businesses, so a company above the thresholds — Gazprom, Sberbank, any major Russian firm — is not in the file at all, and a lookup for it comes back empty. Nor does it contain a street: the finest address it publishes is the town. Individual entrepreneurs make up about half the file and are deliberately not imported here — they are private individuals, named with their patronymic and their personal ИНН, and holding several million of them to answer a question nobody asks would be indefensible.
Russia-specific pitfalls
- Ten digits is a company, twelve is a person. A twelve-digit ИНН on an invoice is a sole trader, not a firm.
- The КПП is not part of the ИНН.
7451269247/745101001is one taxpayer and one of its registrations; only the first half identifies the company. - An ИНН is not proof that НДС is charged. A company on the simplified regime has the same number and adds no VAT.
- Large companies are absent. The only free register keyed by the ИНН covers small and medium-sized businesses.
- No street address. Region, district and town are everything this source publishes.
- Sanctions are your call, not the register's. A lookup says who a number belongs to; whether you may trade with them is a separate check against your own lists.
One API, one response shape
Vatlas turns a business tax number into a company record: legal name, national identifier, legal form, status and address. Russia — the same call and the same response as for every other country covered.

Frequently asked
The ИНН in short
How many digits does an ИНН have?
Ten for a company, twelve for a natural person, including an individual entrepreneur. The last digit — the last two, at twelve — is a modulus 11 check.
Does Russia have a VAT number?
Not a separate one. Russia charges НДС, and the number that identifies the taxpayer on an invoice is the ИНН, issued whether or not the company charges the tax.
What is the КПП next to the ИНН?
The reason-for-registration code: nine digits saying at which tax office and on what ground the taxpayer is registered. One company can have several, one per branch, so it identifies a place rather than a company.
Why does a well-known Russian company return nothing?
Because the only free register keyed by the ИНН holds small and medium-sized businesses. Large companies are not in it, and the full register — the ЕГРЮЛ — is sold by the ФНС rather than published.
Can I get the street address?
Not from this source. It publishes the region, the district and the town of the place of business and nothing finer; the street is in the ЕГРЮЛ, which is not free.
