Why a Lithuania-Aware VAT API

In Lithuania, VAT is known as Pridėtinės vertės mokestis (PVM) and the current standard rate is 21%. Every Lithuania VAT number starts with the prefix LT and follows a fixed structure issued by the Lithuanian tax authority. A generic VAT validator that ignores country-specific quirks will accept malformed input and miss the country’s format rules, and fail to surface the local register number that accountants and auditors actually need.

The vatnode API normalises PVM input, runs the official VIES check, and returns a single JSON shape with the consultation number, company data where published, and the current Lithuania VAT rates inline.

Validating Lithuania VAT Numbers – Code Examples

All three examples validate the same Lithuania VAT number LT212154314. To receive a consultation number back, set your own VAT as requester once in dashboard Account details – then every call, including these, returns a consultation number automatically, with no extra parameters.

curl

curl 'https://api.vatnode.dev/v1/vat/LT212154314' \
  -H "Authorization: Bearer YOUR_API_KEY"

Node.js (fetch)

const res = await fetch(
  'https://api.vatnode.dev/v1/vat/LT212154314',
  { headers: { Authorization: `Bearer ${process.env.VATNODE_API_KEY}` } }
)
const data = await res.json()
console.log(data.valid, data.companyName, data.consultationNumber)

Python (httpx)

import os, httpx

r = httpx.get(
    "https://api.vatnode.dev/v1/vat/LT212154314",
    headers={"Authorization": f"Bearer {os.environ['VATNODE_API_KEY']}"},
)
data = r.json()
print(data["valid"], data["companyName"], data["consultationNumber"])

What You Get Back

A successful response for a valid LithuaniaVAT number, once you've set your VAT as requester in dashboard Account details, looks like this:

{
  "valid": true,
  "vatId": "LT212154314",
  "countryCode": "LT",
  "countryName": "Lithuania",
  "companyName": "Telia Lietuva AB",
  "consultationNumber": "WAPIAAAAXk7ZpY3o",
  "source": "VIES",
  "countryVat": {
    "currency": "EUR",
    "standardRate": 21,
    "reducedRates": [5,12],
    "superReducedRate": null,
    "parkingRate": null
  },
  "verifiedAt": "2026-05-19T08:14:22Z"
}

When the number is not registered, valid is false and company fields are null. The consultationNumber is the EU VIES requestIdentifier – the documented audit reference for reverse-charge ‘reasonable care’ evidence. It is returned once you set your own VAT as requester in dashboard Settings; otherwise it is null.

Lithuania VAT Rates

vatnode returns the current Lithuanian PVM rates inline with every successful response. Today’s rates (standard 21%, reduced 5%, 12%) are sourced from the European Commission TEDB feed, checked daily and updated on any change.

Rate type	Value
Standard	21%
Reduced (1)	5%
Reduced (2)	12%

VIES vs National Fallback for Lithuania

For Lithuania, VIES is the sole authoritative source. vatnode does not run a national-registry fallback for this country today – when VIES is unavailable, the API surfaces a structured VIES_UNAVAILABLE error with retry guidance so you can degrade gracefully rather than silently accept unverified numbers.

Cached VIES responses (15-minute TTL on identical VAT IDs) absorb the majority of short outages transparently. For the full per-country fallback status, see the coverage matrix.

Lithuania VAT API – FAQ

Is the Lithuania VAT number the same as the company registration number?

No. The Lithuanian PVM number is a separate code from the legal entity code. vatnode looks the company up in the national register and returns the legal entity code in registryCode, with its local name (juridinio asmens kodas) in registryCodeName.

How fast is Lithuania VAT validation through vatnode?

Cached responses return in single-digit milliseconds. Live VIES lookups for Lithuania typically complete in under one second; a 15-minute Redis cache is applied to identical VAT IDs.

Does the API work for Lithuanian sole traders and small businesses?

Yes. If a Lithuanian sole trader or small business is registered for PVM and listed in VIES, vatnode validates the number and returns the same response shape as for corporate entities. The valid field is true regardless of legal form.

Does vatnode handle VIES outages for Lithuania?

vatnode caches recent VIES responses and surfaces a clear VIES_UNAVAILABLE error code with structured retry guidance. vatnode does not use a national validity fallback for Lithuania — only the VAT register itself can confirm a VAT registration, so during a VIES outage validation defers to the cached result or returns the error for safe handling.

What is the consultation number returned for checks in Lithuania?

The consultationNumber is the VIES requestIdentifier — a reference returned by VIES that proves the check was performed against the official EU register on a specific date. It shows that you checked, not that the counterparty stayed valid afterwards, and it is returned once you set your own VAT as requester in dashboard Account details — including for Lithuania.
