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 — there is no cross-registry merging. Two Bolagsverket API versions are used for different purposes:-
Bolagsverket Foretagsinformation API v4 — 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 — 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 — 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 retrieving the UBO Extract (Registret over verkliga huvudman) document from Bolagsverket’s website, then parsing the PDF content with AI. Bolagsverket does not yet expose UBO data through a structured API endpoint.Company Identifiers
Query Identifiers
Identifiers in API Response
Search Capabilities
Identifier normalization: The search request strips the
SE prefix and trailing digits from VAT numbers, removes hyphens from organisation numbers and personnummers, and detects sole traders automatically by the personnummer format (12 digits, birth-month digits 01-12 in positions 3-4).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
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
“Aktiv” is not returned by the API — 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)
Ongoing Procedure Statuses (AvvecklingsOmstruktureringsforfarande)
Legal Forms
The local legal form (organisationsform.klartext) is preserved from Bolagsverket and deterministically mapped to an English translation. The standardized form and iso20275Code are AI-enriched.
Key Business Forms
Housing and Cooperative Forms
Non-Profits and Foundations
Financial Institutions
Branch Offices and European Forms
Legacy and Other Forms
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.
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
Auditor Roles
Signatory and Representative Roles
Partnership Roles
Other Administrative Roles
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 “(Representative)”.
Shareholders
Bolagsverket does not publish a share register. Ownership is restricted to authorities and the company’s own shareholders, so there is no register source for it. What theshareholders datapoint reads instead is the ownership note in the company’s annual report. Swedish companies are not required to disclose ownership there, so most return none. Names and holdings are extracted by AI from the filing, so verify against the source before relying on them for compliance.
Sole traders (enskild firma) have no share capital, so the datapoint does not apply to them at all: it returns an explicit datapoint_not_applicable response and the owner is returned under legalRepresentatives. See Sole Entrepreneurs & Non-Profits.
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: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

Purchasable Documents (Website)
Historical Certificates (HISTBEV) and English Certificates (ENGINTYG) require authenticated login to Bolagsverket and are not available programmatically. The available purchasable documents vary by legal form and entity type. The system automatically queries the correct document catalog.
