Data Sources
All company data is sourced from Bolagsverket (Swedish Companies Registration Office), the official government agency responsible for registering companies, partnerships, associations, and other legal entities in Sweden. Bolagsverket was established in 2004 when it took over registration duties from the Patent and Registration Office (PRV). For a given entity, data comes from a single source โ there is no cross-registry merging. Two Bolagsverket API versions are used for different purposes:-
Bolagsverket Foretagsinformation API v4 โ The primary source for company profile data. This is a paid API that provides comprehensive structured data: company name, legal form, status, registration and incorporation dates, registered address, share capital, activity description, board members and officers (funktionarer), signing rules (firmateckning), financial reporting periods, and articles of association details. Used for the
companyProfiledata point. - Bolagsverket Vardefulla Datamangder API v1 โ A free open data API providing basic company information. Used for search by registration number and for annual report document listings (dokumentlista endpoint). Returns: company name, legal form, address, registration date, and status indicators. Also provides the annual reports document listing for each company.
-
Bolagsverket Foretagsinfo Website API โ The Bolagsverket public website (
foretagsinfo.bolagsverket.se) exposes a product catalog API that lists available purchasable documents per company. This is used to determine which paid documents (trade register extract, articles of association, statutes, minutes, UBO extract, current assignments) are available for a given company and legal form.
Search by company name is retrieved from the official registry because the Bolagsverket name search functionality does not have a public REST API endpoint. Identifier-based searches use the v1 API directly.
Ultimate Beneficial Owners
UBO data is obtained by purchasing the UBO Extract (Registret over verkliga huvudman) document from Bolagsverketโs website, then parsing the PDF content with AI. Bolagsverket does not yet expose UBO data through a structured API endpoint.Company Identifiers
Query Identifiers
| Identifier Type | Format | Example | Notes |
|---|---|---|---|
| Organisationsnummer | 10 digits (NNNNNN-NNNN or NNNNNNNNNN) | 5560125790 or 556012-5790 | Primary identifier. Hyphen is optional. |
| VAT number | SE + 12 digits | SE556012579001 | Swedish VAT format: SE prefix + org number + two-digit suffix (usually 01) |
Identifiers in API Response
| Identifier | Format | Example | Notes |
|---|---|---|---|
id | 10 digits (no hyphen) | 5560125790 | Always returned without hyphen |
registrationNumber | 10 digits | 5560125790 | Same as id |
Search Capabilities
| Search Type | Pattern | Example | Match Type | Expected Results |
|---|---|---|---|---|
| By Organisationsnummer | 10 digits (with or without hyphen) | 5560125790 or 556012-5790 | Exact | Single company (1 result) |
| By VAT number | SE + 12 digits | SE556012579001 | Exact | Single company (1 result) |
| By company name | Text string | "Volvo" | Contains | Multiple results |
Identifier normalization: The search workflow automatically strips the
SE prefix and trailing digits from VAT numbers, and removes hyphens from organization numbers before querying the Bolagsverket API.Search uses both a live registry lookup and an official registry query. Identifier searches (organisationsnummer, VAT) query the Bolagsverket v1 API directly. Name searches query the official registry because no public name search API exists.
Quirks & Gotchas
| Quirk | Details |
|---|---|
| No shareholders from Bolagsverket | Shareholder information is restricted to authorities and the companyโs own shareholders. It is not available through any public API or document. The shareholders array is always empty. |
| UBO = control extent, not ownership | Bolagsverket reports control extent (Omfattning) for UBOs, not ownership percentage. Multiple UBOs can each show 100% control. This reflects influence over the company through shares, agreements, or intermediary entities โ not economic stake. |
| All activity codes are AI-inferred | Sweden does not assign standard classification codes. The verksamhetsbeskrivning (activity description) is a free-text field in Swedish, and all ISIC/NACE codes are derived by AI. isAIInferred is always true. |
| Active = empty status array | An active company has an empty organisationsstatusar array from Bolagsverket. Any status entry means the company is inactive. This is the opposite of most registries which explicitly mark companies as active. |
| Status code system is complex | Bolagsverket uses dozens of numeric status codes across two categories: AvregistreradOrganisationstyp (struck off the register โ codes 21, 31, 37, 41, 51, 53, 60-64, 70, 73, 74, 91, 98) and AvvecklingsOmstruktureringsforfarande (ongoing settlement/restructuring โ codes 11, 20, 32, 45, 49, 75, 80, 85, 90, 91, 96). |
| All documents are in Swedish | All documents from Bolagsverket (annual reports, trade register extracts, articles of association, UBO extract, etc.) are written in Swedish. English certificates require login and are not available programmatically. |
| Annual reports: API vs purchasable | Annual reports come from two sources: (1) free individual filings via the v1 API dokumentlista endpoint (ZIP format containing original filing), and (2) a paid compilation of all years from the website (single PDF). |
| Legal form is AI-enriched | Local Swedish legal forms are deterministically mapped to English translations via a static codelist. However, the standardized form and iso20275Code are AI-enriched. |
| Share capital in SEK only | Share capital for AB companies is always denominated in Swedish Kronor (SEK). |
| Purchasable documents vary by legal form | The available purchasable documents depend on the companyโs legal form code. For example, โArticles of Associationโ (Bolagsordning) applies to AB companies, while โStatutesโ (Stadgar) applies to associations. |
| Document purchase requires payment flow | Purchasable documents involve a 5-step process: temporary inbox creation, website payment, document download, PDF extraction from ZIP, and invoice forwarding. Delivery takes approximately 5 minutes. |
Mappings
Company Status
Status is determined deterministically from the Bolagsverket register. An emptyorganisationsstatusar array means the company is active. Any status entry triggers mapping through the status code system.
Active Status
| Local Status | English Translation | Standardized Status |
|---|---|---|
| Aktiv | Active | ACTIVE |
โAktivโ is not returned by the API โ it is inferred from the absence of any status entries. When
organisationsstatusar is empty or undefined, the company is considered active.Struck-Off Statuses (AvregistreradOrganisationstyp)

Bolagsverket maintains approximately 30 standardized legal form codes. The
iso20275Code is AI-enriched and available for common forms like AB (XJHM), HB (BEAY), and EK (C61P). Additional legacy forms may appear in historical records. The API preserves the localName exactly as returned by Bolagsverket.Legal Representatives
These roles have statutory authority to bind the company and are classified as legal representatives. Role codes are from the official Bolagsverket funktionarsroller codelist. Roles are deterministically mapped to English translations; theiso5009Code is AI-enriched.
| Code | Swedish Name | English Translation | Standardized |
|---|---|---|---|
| OF | Styrelseordforande | Chairman | Chairman |
| VD | Verkstallande direktor | CEO | CEO |
| LE | Styrelseledamot | Board Member | Board Member |
| SU | Styrelsesuppleant | Deputy Board Member | Board Member |
| SUPP | Suppleant | Deputy Board Member | Board Member |
Role priority: When a person holds multiple roles, the system applies a priority: OF (Chairman) > VD (CEO) > LE (Board Member) > SU/SUPP (Deputy). Only the highest-priority role is assigned as the legal representative role for that person.
Other Key Persons
All other officer roles (funktionarer) are classified as other key persons. Both individuals and corporate entities can hold these roles (e.g., an auditing firm as auditor). Role codes are standardized by Bolagsverket.Executive Management Roles

| ARB | Arbetstagarrepresentant | Employee Representative | Supervisor |
| FTR | Forsakringstagarrepresentant | Policyholder Representative | Supervisor |
A person or entity can hold multiple roles simultaneously. For legal representatives, the highest-priority role is selected. For other key persons, each non-legal-representative role is listed separately. When an organization holds a role (e.g., an auditing firm), its representative person is also listed with the suffix โ(Representative)โ.
Shareholders
Bolagsverket does not provide shareholder information through any public API or document. Shareholder data is restricted to authorities and the companyโs own shareholders. Theshareholders array is always empty.
Activity Code Mapping
Sweden does not use a national activity code classification in the Bolagsverket registry. Instead, companies register a free-text verksamhetsbeskrivning (activity description) in Swedish. The system uses AI enrichment to derive standardized activity codes:| Classification | Source | Example | AI Inferred? |
|---|---|---|---|
| Activity description | Bolagsverket (verksamhetsbeskrivning) | โUtveckling och forsaljning av programvaraโ | No (official) |
| ISIC | AI-derived from activity description | 6201 - Computer programming activities | Yes (always) |
| NACE | AI-derived from activity description | 62.01 - Computer programming activities | Yes (always) |
All ISIC and NACE codes for Sweden are AI-inferred because Bolagsverket does not assign standard classification codes. The AI derives codes from the Swedish-language activity description text. The
isAIInferred flag is always true for Swedish activity codes.Data Availability
