How to Search Sweden Company Registry Data: Bolagsverket

Finland gives its company register away — free search, free extracts, a free daily API. Sweden took the other road. It built one of Europe’s deepest, best-kept registers and, for decades, treated the data as a product to be sold. That is now shifting: in mid-2025 a genuinely free firmographic API opened at Statistics Sweden. But the authoritative layer — Bolagsverket’s certified documents, annual reports and bulk API — still runs on a meter, and the beneficial-owners register has closed to the public. This is a clear-eyed guide to what Swedish company data contains, what it costs to reach, what the financials hold, and where the open road ends.

Where Swedish company data lives

Sweden splits company data across two public bodies, and knowing which holds what saves a lot of wasted clicks and spend.

The authoritative source is Bolagsverket, the Swedish Companies Registration Office in Sundsvall. It registers companies, issues the organisationsnummer (corporate identity number), and receives annual reports, mortgages and liquidations. It is the legal record — identity, status, board, signatories, filings. Alongside it, Statistics Sweden (SCB) keeps the statistical business register (Foretagsregistret), drawing on Tax Agency data, and — as of 2025 — serves basic firmographics through a free API. The third layer, the Register of Beneficial Owners (verkliga huvudman), is also held by Bolagsverket but, unlike the company record, is no longer openly public.

The organisationsnummer is the thread that ties it together: ten digits in the form NNNNNN-NNNN, where the first digit signals the legal form (a 5 marks an aktiebolag). The Swedish VAT number is the same ten digits prefixed with SE and suffixed with 01 (e.g. SE556677889901). For formats across borders, see our VAT number formats by country.

How many companies exist — and how many actually trade

Sweden’s statistical register holds roughly 1.3 million registered entities. But that figure flatters the economy: it includes housing co-operatives (bostadsrattsforeningar) and deceased estates (dodsbon) that aren’t businesses in any ordinary sense. Strip those out and SCB counts about 1.2 million in the actual business sector — and within that, the workhorse is unmistakable: the aktiebolag (AB), the limited company, of which there are around 800,000 active.

The AB dominates because it is flexible and cheap to start: since 2020 the minimum share capital is just SEK 25,000 (a public limited company, publikt aktiebolag, needs SEK 500,000). The other forms — sole traders (enskild firma), trading and limited partnerships (handelsbolag, kommanditbolag), economic associations and foreign branches (filial) — make up the rest. Swedish foundations (stiftelser) sit in a separate register run by the county administrative boards, not Bolagsverket.

A record bankruptcy wave — even as new companies climb

Two things have been true at once in Sweden: a steady stream of new companies, and the worst run of business failures in three decades. Both are real.

Take formation first. New limited-company registrations slid from their 2021 record through the downturn — roughly 49,800 new aktiebolag in 2023 and 46,785 in 2024, the lowest in six years — before rebounding to 52,066 in 2025, up 11%. The engine of new companies is running again.

Yet the failure side tells the harder story. According to Tillvaxtanalys, Sweden’s official statistics agency for bankruptcies, company bankruptcies climbed from 6,849 in 2022 to 10,762 in 2024 — the highest number since 1996, with about 94% of them limited companies. The driver was the familiar one: high interest rates and weak demand squeezing construction, retail and hospitality. In 2025 the count held near that record (around 10,700), so the surge has plateaued at a historic high rather than receded.

What is free, what costs money, and how much

This is where Sweden differs sharply from its neighbour. Finland publishes a free, daily open-data API that even includes financial figures. Sweden’s authoritative agency, Bolagsverket, is partly fee-funded: basic search is free, but the certified documents, the financial statements and the programmatic feed sit behind a paywall. The free route that opened in 2025 is SCB’s — and it carries firmographics, not financials.

So the honest summary: verifying that a company exists is free; getting the documents and structured data that due diligence actually runs on is not. The basic Bolagsverket search confirms identity, status and board. SCB’s free API, opened after a June 2025 rule change that ended its data charges, is excellent for firmographics at scale — but it won’t hand you a balance sheet. For annual reports, certified extracts or a high-volume register feed, you pay Bolagsverket, sign an agreement, and (for the documents path) often clear a BankID step that adds friction for non-Swedish users.

Financials: who files, and what the accounts contain

Swedish disclosure is broad and the data is genuinely useful. Every aktiebolag must file an annual report (arsredovisning) with Bolagsverket within seven months of its financial year-end — in Swedish — and the obligation applies even to dormant companies and those in liquidation. From financial years beginning on or after 1 January 2025, economic associations must file too. Miss the deadline and Bolagsverket issues a late-filing penalty (from SEK 1,250 for a private company, higher for a public one); it has no power to grant an extension.

Two points the headline rules don’t tell you:

• The accounting framework signals the company’s size. Small companies report under K2 (simplified) or K3 (principles-based); larger and listed groups use IFRS (K4). A K2 filing is a small company by definition — useful triage before you even read the numbers.
• Most small companies aren’t audited. Since 2010, a private AB can skip the statutory audit if it does not exceed more than one of three thresholds — net turnover SEK 3 million, balance sheet total SEK 1.5 million, and an average of 3 employees. These are low by international standards, so the bar to needing an auditor is reached quickly — but the long tail of micro-companies still files unaudited accounts.

Shareholders and beneficial owners: the closed door

Sweden is transparent about who runs a company and far less so about who owns it — with one genuinely Swedish twist.

• Directors and signatories are public. The Bolagsverket record names the board, the managing director where there is one, and who may sign for the company — the basis for confirming authority.
• Shareholders are not in the register — but the share book is. Bolagsverket states plainly that it does not register the shareholders of a limited company. Instead, each AB keeps its own share register (aktiebok), and by law that book must be made available to anyone who asks — at the company’s premises, not online. So ownership is technically open, but you have to go and get it.
• Ultimate ownership runs through the gated UBO register. Companies must file beneficial owners — natural persons holding more than 25% of shares or votes, or otherwise in control — with Bolagsverket within four weeks of registration. That register is the part the public can no longer freely browse.

What’s changing

Three currents are reshaping access, pulling in different directions.

Open data is advancing — on the firmographic side

The clearest shift is SCB’s. A rule change effective 26 June 2025 ended SCB’s charges for business-register data, and the agency opened a free API carrying current company and establishment information. That makes basic Swedish firmographics free at scale for the first time — though it stops short of the financial statements, which remain with Bolagsverket.

UBO access is being rebuilt

The beneficial-owners API ran on ageing infrastructure and has been retired, with a replacement planned. Until it returns, programmatic UBO access faces a gap, and manual access stays gated behind the legitimate-interest test — the EU-wide settlement after the 2022 court ruling.

The EU AML Package lands in 2027

Sweden’s restricted owners register is part of the bloc-wide reset. The single rulebook — the AMLR (Regulation (EU) 2024/1624) and AMLD6 (Directive (EU) 2024/1640) — fully applies from 10 July 2027, with the new EU Anti-Money-Laundering Authority (AMLA) already operating in Frankfurt. It standardises the legitimate-interest test, keeps full access for authorities and obliged entities, and interconnects national UBO registers. The practical read for compliance teams is the same as elsewhere in the EU: build onboarding for a legitimate-interest world — see our explainer on what AMLD6 actually changes.

How to access Swedish data at scale

For a single company, the free Bolagsverket search is instant. The volume picture is more layered than Finland’s: there are two free routes and two paid ones, and the right mix depends on whether you need firmographics, documents, or both.

Sweden also participates in the EU’s Business Registers Interconnection System (BRIS), so basic data is reachable through the European e-Justice portal too — and our guide to searching company information across the EU walks the practical routes. But for most cross-border teams the job is rarely “get Sweden” in isolation — it is “get Sweden in the same schema as the rest of the Nordics and 40 other European registers,” joined to financials and ownership. That is why Sweden sits in our directory of official company registries across 44 European countries, beside our deep-dives on Finland, Norway and Denmark. For where APIs exist and where they don’t, see our global registry-API map.

What the register won’t tell you

Sweden’s data is high quality — but quality is not the same as completeness or reach. The honest list of blind spots is what separates a thorough Swedish file from a false sense of security.

None of this makes the register weak — it makes it a premium primary source that still needs structuring, translating and supplementing. The fix is registry-sourced data delivered already resolved, refreshed daily, and joined to the ownership and financial layers the public services keep apart and behind paywalls.
