The Ukrainian ЄДРПОУ

One company, two numbers, seven shared digits

The ІПН is built from the ЄДРПОУ. Its first seven digits are the first seven of the ЄДРПОУ; the remaining five are a serial and the code of the tax office. The eighth digit of the ЄДРПОУ — the one the ІПН leaves out — is a check digit, so it can be computed back:

• ЄДРПОУEight digits: seven of sequence and a modulus 11 check. Issued on registration, kept for the company's whole life, and the key the state register files it under.
• ІПНTwelve digits, issued only on registration for ПДВ: the first seven of the ЄДРПОУ, a serial, then the tax office. Cancelled if the registration is.

So UA037771118081 and UA03777114 are the same company, and Vatlas treats them as one: the twelve-digit form is reduced to the eight-digit one before anything is looked up, so both spellings return the same record and build one history.

ЄДРПОУ, ІПН and РНОКПП — which is which

• ЄДРПОУThe legal entity. Eight digits, on every contract and every invoice.
• ІПНThe VAT registration. Twelve digits, and a company that is not registered for ПДВ simply has none.
• РНОКППTen digits, the personal tax number of an individual — what a sole trader (ФОП) trades under. It is not published anywhere, for reasons below.

Finding the company behind the number

What the Ministry of Justice publishes

The ЄДР — Єдиний державний реєстр юридичних осіб, фізичних осіб-підприємців та громадських формувань — is published in full, every week, as open data under Creative Commons Attribution, with no account and no key. It is what Vatlas imports: a 319 MB archive a week, holding the name, the short name, the organisational-legal form, the state of the entity and its registration dates, keyed by the ЄДРПОУ.

What the register does not contain

Two things, and both are the war rather than an oversight.

There is no address. Not a truncated one, not a town: місцезнаходження was withheld from the published dataset under martial law, and there is no address field in the schema at all. A Ukrainian lookup returns a name, a legal form and a status, and stops there.

There is no ПДВ status. The register that says whether a company's VAT registration is live is the State Tax Service's own, and it is closed: its open-data publication stopped on 23 February 2022, the day before the invasion, and the tax service's public register search now answers with a single sentence — access to the public electronic registers is restricted for the duration of martial law. So a lookup can tell you which company an ІПН belongs to; it cannot tell you whether that registration is still in force.

Ukraine-specific pitfalls

• Eight digits and twelve digits are one company. The twelve-digit ІПН reduces to the eight-digit ЄДРПОУ; do not key two records to them.
• An ІПН is a VAT registration, a ЄДРПОУ is not. Every company has the second; only a registered payer has the first.
• Sole traders cannot be looked up. The ФОП half of the register publishes no identifier at all — a name, a status and dates — so there is no number to find them by.
• No address, from any free source. This is the register's published content under martial law, not a gap in the lookup.
• A company in в стані припинення is still trading. Winding up is not struck off; Vatlas reports it active, because it can still invoice you.
• 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. Ukraine — the same call and the same response as for every other country covered.

meta.source names the register that answered (SIRENE, ARES, VIES…) and meta.sourceDate the day it said so: the publication date of the file for a register we import, the day of the call for one we query live. The shape of the response never changes from one country to the next.
