How do I look up a Latvian company by registration number from an API?

Call GET /companies/search?company_number=40003032949&country=LV. An LV prefix is optional, and the mod-11 check is enforced; a number that is malformed or fails the check is a 400 validation error rather than an empty list.

Can I look up a Latvian company by VAT number?

Yes. The Latvian VAT number is LV plus the 11 digits of the registration number, for example LV40003032949. Pass it as vat with country=LV and it resolves to the same company. It comes from the State Revenue Service’s list of VAT payers, so a company that is not on the list has none; to check a number against VIES, use GET /vat/ followed by the number.

Is the registration number check enforced?

Yes for the 11-digit numbers: the weights are 9, 1, 4, 8, 3, 10, 2, 5, 7, 6, 1 and the sum must leave 3 modulo 11. The oldest 9-digit codes carry no check digit. An 11-digit number starting 0 to 3 is a personal code and is refused.

Does the Latvian record include officers, company events or insolvency notices?

Company events yes; officers and insolvency notices no. Latvia is company-level: legal name, legal form, status, registered address with the region, share capital and previous names. There are no officers, no registry-compliance signal and no activity code. Register-change events (name, status, legal form and registered address, dated when the change first appears in the register data, none before the first load in October 2026) and monitoring are available. Liquidation, insolvency and legal protection proceedings show in the status.

Which Latvian entities does it cover?

Companies and the other legal persons of the commercial register. Individual merchants (IK) and other natural persons are never served, so a lookup of one returns nothing even though it exists.

Can I call the API from the browser?

You can, but a key in the browser is public. Proxy the search through your server, as in the sample above. Rate limits are per key.

Is there a way to try it before signing up?

Yes: the free registration number lookup runs the same call with a shared key.

Company records from the Register of Enterprises of the Republic of Latvia (Uzņēmumu reģistrs): legal name, legal form, status (including liquidation, insolvency and legal protection proceedings), registered address with the region, share capital, previous names and dates; the VAT number comes from the State Revenue Service’s list of VAT payers; with register-change events and monitoring, but no officers, no registry-compliance signal, no activity code and no insolvency notices. Individual merchants and other natural persons are never served. The Latvian VAT number (LV plus the registration number) is searchable with vat.
