The answer returns every step’s result, so your agent can show or check each one.

Inputs

Field	Type	Required	What it is
`org_number`	string	Yes	Swedish organization number
`vat_number`	string	No	EU VAT number with country prefix (e.g. ATU14189108). Optional — used for VIES validation when the registry lookup does not return one (e.g. AT, SK); auto-derived from registry data where possible.

Limitations

Bolagsverket’s open company data covers names, legal forms, status, addresses, SNI codes, registration dates and insolvency flags. Annual-report figures such as revenue, profit, employee counts and equity are not included.
From step: Swedish Company Data
What to do instead: Order an annual report or financial statement extract from Bolagsverket.
Looks up companies by organisation number only; it does not search by name.
From step: Swedish Company Data
What to do instead: Find the organisation number on an official company document or in the registry, then pass it as `org_number`.
Sole traders (enskild näringsidkare) can have several companies registered under the same personal identity number. Lookup returns only the first entry, so other registrations under that number are not included.
From step: Swedish Company Data
What to do instead: Prefer aktiebolag organisationsnummer (10 digits starting 2–9) for unambiguous single-entry lookups.
Deregistered companies (avregistrerad) still return registry data, but the data reflects the state at deregistration. `is_active` is false and `deregistered_date` is populated.
From step: Swedish Company Data
What to do instead: Always check the `is_active` and `deregistered_date` fields before using returned data for live decisions.
VIES can be unavailable or throttle requests under unpublished per-member-state limits. Transient faults are retried, and cached results, including older fallback results, can be returned during outages.
From step: EU VAT Validation
What to do instead: Lookups within 48 hours can use cached results; if VIES is unavailable and no cached result exists, retry later.
Results can be cached for 48 hours, and national registry changes can take a further 24 hours to appear in VIES. Check the national tax authority directly for same-day registration or deregistration confirmation.
From step: EU VAT Validation
What to do instead: For real-time same-day verification, contact the national tax authority directly.
Swiss UID validation returns valid or invalid only, without a company name or address. This tool does not perform the separate enrichment lookup, whose public service is limited to 20 requests per minute.
From step: EU VAT Validation
What to do instead: For Swiss company name + address, call the swiss-company-data capability.
GB VAT numbers return a credentials-pending error when the HMRC connection is not configured.
From step: EU VAT Validation
What to do instead: Use vat-format-validate for GB format checks; it does not confirm VAT registration.
Sanctions lists updated daily from OFAC, EU, and UN sources — newly sanctioned entities may take up to 24 hours to appear
From step: Sanctions Check
What to do instead: For same-day compliance, subscribe to OFAC's RSS feed and cross-reference against today's additions
Name matching uses fuzzy logic — common names may produce false positives. Always verify flagged results
From step: Sanctions Check
What to do instead: Filter results by match confidence score and verify flagged entities against the primary sanctions list PDF
Covers entities with LEI registration via GLEIF — only ~2.5 million entities worldwide have LEIs, primarily financial institutions
From step: LEI Lookup
What to do instead: If no LEI is found, search by company name and jurisdiction; consider that smaller entities may not have an LEI
