Latvia VAT API — Validate Latvia VAT Numbers in Real Time
REST JSON endpoint for verifying Pievienotās vērtības nodoklis (PVN) numbers against the official EU VIES register, with national registry fallback where available and a VIES consultation number on every successful check.
Why a Latvia-aware VAT API
In Latvia, VAT is known as Pievienotās vērtības nodoklis (PVN) and the current standard rate is 21%. Every Latvia VAT number starts with the prefix LV and follows a fixed structure issued by the Latvia tax authority. A generic VAT validator that ignores country-specific quirks will accept malformed input, miss the country's format rules, and fail to surface the local registry identifier that accountants and auditors actually need.
The vatnode API normalises PVN input, runs the official VIES check, falls back to the Latvia national company registry when VIES is unavailable, and returns a single JSON shape with the consultation number, company data where published, and the current Latvia VAT rates inline.

const data = await res.json()
console.log(data.valid, data.companyName, data.consultationNumber)import os, httpx
r = httpx.get(
"https://api.vatnode.dev/v1/vat/LV40003032949",
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 Latvia VAT number looks like this:
{
"valid": true,
"vatId": "LV40003032949",
"countryCode": "LV",
"countryName": "Latvia",
"companyName": "Latvenergo AS",
"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.
Latvia VAT rates
vatnode returns the current Latvia PVN rates inline with every successful response. Today's rates (standard 21%, reduced 5%, 12%) are sourced from the European Commission TEDB feed and refreshed daily.
| Rate type | Value |
|---|---|
| Standard | 21% |
| Reduced (1) | 5% |
| Reduced (2) | 12% |
VIES vs national fallback for Latvia
VIES is the primary data source for Latvia validation — it is the authoritative EU register and the only source that produces a consultation number. When VIES returns a transient error (timeout, MS_UNAVAILABLE, SERVICE_UNAVAILABLE), vatnode automatically queries the Latvia national company registry as a fallback so your checkout or invoicing pipeline keeps working.
The response includes a source field that tells you which system answered — VIES for the EU register, or the Latvia national-registry source code when the fallback ran.
Latvia is one of the EU countries where vatnode keeps validating during EU VIES outages via a direct national registry adapter. See coverage matrix for the full list.
Latvia VAT API — FAQ
Is the Latvia VAT number the same as the company registration number?
No. The Latvia PVN number is issued by the tax authority for VAT purposes; the national registry identifier is a separate ID issued by the company registry. vatnode returns both fields (registryCode + registryCodeName) for Latvia when the data is available.
How fast is Latvia VAT validation through vatnode?
Cached responses return in single-digit milliseconds. Live VIES lookups for Latvia typically complete in under one second; a 15-minute Redis cache is applied to identical VAT IDs.
Does the API work for Latvia sole traders and small businesses?
Yes. If a Latvia sole trader or small business is registered for PVN 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.
What happens if EU VIES is down for Latvia?
vatnode falls back to the Latvia national registry adapter when VIES returns a transient error (timeout, MS_UNAVAILABLE). Validation keeps working from the national source; the response includes a source field so you can tell which system answered.
What is the consultation number returned for Latvia checks?
The consultationNumber is the VIES requestIdentifier — a unique reference issued by the EU VIES service that proves the check was performed against the official EU register on a specific date. It is the EU's documented mechanism for "reasonable care" evidence under the reverse-charge rules and is returned on every successful VIES validation, including Latvia.
