Lithuanian Company Checker

What does Lithuanian Company Checker do?

Lithuanian Company Checker verifies Lithuanian companies in bulk against four official state sources at once. Give it a list of 9-digit legal entity codes and for each one you get back the legal name, legal form, legal status, VAT registration with its full history, an independent VIES confirmation, and the exact amount the company owes the tax authority.

The combination is the point. Each of the four sources answers a question the others cannot:

Source	The question only it answers
JAR (Register of Legal Entities)	Is the company in liquidation, bankruptcy or restructuring? Was it deregistered, and when?
VMI tax register	What is its VAT number, since when, and was the registration ever cancelled?
VMI debtor list	How much does it owe the tax authority right now, and how much of that is past due?
EU VIES	Does the EU confirm the VAT number is valid for cross-border trade?

A supplier can look perfectly alive in the tax register while the business register already lists it as Likviduojamas dėl bankroto. A name-and-address lookup will not tell you that. This actor will.

Verified zero is not a missing check

The debtor list only contains debtors, so an empty answer means verified: no tax debt, and the output says taxDebtEur: 0 rather than null. A null appears only when the check itself could not be performed, and the provenance row says why. The same honesty applies everywhere: when a source is down, the affected fields are null and flagged, never silently guessed.

Typos never reach the register

Lithuanian legal entity codes carry a checksum digit. Every code is validated locally first; a code that fails the checksum is reported as a typo, costs nothing, and never generates a request. A code that passes the checksum but does not exist is reported as such, free of charge, after checking both the register of active entities and the register of deregistered ones, because "it existed and was dissolved in 2019" is a different answer than "it never existed".

Input

{
  "companies": [
    "121215434",
    { "code": "123033512", "reference": "supplier-42" }
  ],
  "checkTaxDebts": true,
  "includeVies": true
}

Strings and objects can be mixed freely. The optional reference is returned unchanged so you can join results back to your own system.

    { "source": "EU VIES", "ok": true }
  ]
}

Watch a list for changes

Checking a supplier once is useful. Checking the same list every morning and reading only what changed is what keeps you out of trouble. Give the run a watch name (or save it as a task and schedule it) and every later run compares its results with the previous one: a company that turned inactive, a new risk flag, a VAT registration cancelled, a published account that disappeared. The differences are stored in the CHANGES record of the run, ready for an integration or an email. The comparison itself is free.

What it does not do

The register's address data sits behind a chain of separate registers and is not included yet; the address field is always null for now. If you need addresses, say so in a review and it moves up the list.

Frequently asked questions

What does an unmatched row cost? Nothing. Rows that fail the checksum or that no register knows are returned with an explanation and are never charged.

Is a zero tax debt a real answer? Yes. The debtor list contains only debtors, so an empty result is a verified zero, reported as 0. A null appears only when the check itself could not run.

Why does the answer distinguish deregistered from never existed? Because they mean different things when you vet a counterparty. A code found among deregistered entities returns the company with its removal date; a code no register knows is reported as non-existent.

Where does the data come from? The Lithuanian Register of Legal Entities and the State Tax Inspectorate (VMI), both through the national open data portal, plus EU VIES. Every value carries its source and timestamp.

Where the data comes from

All four sources are official, public and free of charge: both the Register of Legal Entities and the tax authority publish their data through the national open data portal. No scraping of web pages, no proxies, no headless browser, which keeps runs cheap and the data authoritative.

This is the Lithuanian sibling of our Czech & Slovak and Romanian company checkers. All three share the same validation engine and the same billing rule: unmatched rows are free.
