Company Register Search
company_register_searchSearch the NATIONAL BUSINESS REGISTERS by company name and get the register's own id back — a Companies House number, a Norwegian organisasjonsnummer, a Finnish business id, a SIREN, a Japanese corporate number, an Estonian registry code, a CNPJ, or an LEI. Use this when you want the OFFICIAL REGISTERED ENTITY and the country is not the US, or when you do not know which country it is. Registers searched: Companies House (GB), Enhetsregisteret (NO), PRH/YTJ (FI), Sirene (FR), 法人番号公表サイト (JP), RIK e-Business Register (EE), and the GLEIF LEI crosswalk, which reaches jurisdictions we have no register pack for (DE, SE, AU, SG...). THIS TOOL REFUSES TO GUESS, and that is its point: when two different companies match a name equally well it answers match_status: "ambiguous" with BOTH, rather than naming one. A one-word trading name usually IS ambiguous — "Bolt", "Apple", "Next", "Sea", "DNB" each match a well-known group AND unrelated micro-entities whose registered name is exactly that word — so pass country when you know it. Every response names EVERY register it asked under searched[], with that register's own as-of date and row count, and a register that could not be reached carries an error there rather than reading as zero rows: "we could not ask Companies House" is never the same answer as "this company is not in Britain". related[] holds entities that collapsed INTO the match — the same company seen through another register, or another country's arm sharing its LEI — so a multinational returns one answer rather than tying with itself. NOT A PEOPLE SEARCH: sole traders and other natural persons are excluded on the publisher's own legal-form field, never guessed from the shape of a name. For US public companies prefer resolve_entity (CIK + ticker + FIGI); the two share this same matcher, and resolve_entity returns these register fields too.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | The company name as you have it, in its own script. Pass it VERBATIM — do not strip the legal form ("Oyj", "AS", "株式会社", "Ltd"): in Japanese the form is a PREFIX as often as a suffix and 株式会社花王 and 花王株式会社 are DIFFERENT companies, so the form is often the only evidence that separates two candidates. Diacritics, full-width characters and kana are all handled. | |
| limit | No | Maximum candidates to return, 1-50 (default 10). Does not change which registers are asked, only how many rivals come back. | |
| country | No | OPTIONAL ISO 3166-1 alpha-2 of the register you mean ("GB", "NO", "FI", "FR", "JP", "EE", "BR"). Narrows the fan-out, and is frequently the difference between an answer and `ambiguous` on a short name. The GLEIF crosswalk is asked whatever you pass, because for several jurisdictions it is the only register we can name at all. |
