Limitations

Data from Companies House API — LLPs and Scottish LPs included, but sole traders and partnerships are not registered
From step: UK Company Data
What to do instead: For sole traders, check HMRC's contractor verification or use the business name with google-search
Coverage varies significantly by jurisdiction — UK and EU have the best data; many countries have no public UBO register
From step: UK Beneficial Ownership
Data may lag real ownership changes by months
From step: UK Beneficial Ownership
Complex ownership chains through multiple jurisdictions may not be fully resolved
From step: UK Beneficial Ownership
Currently covers UK companies only. Beneficial ownership data depends on company filings — some companies may not have filed PSC information
From step: UK Beneficial Ownership
What to do instead: For non-UK companies, use company-data capabilities for the relevant country and check local UBO registries
PSC data is self-reported by companies to Companies House. Accuracy depends on the filing company — data is not independently verified
From step: UK Beneficial Ownership
What to do instead: Cross-reference with other compliance data sources for high-value due diligence
Companies listed on regulated markets (e.g. London Stock Exchange) are exempt from PSC filing requirements
From step: UK Beneficial Ownership
What to do instead: For listed companies, check shareholder registers and annual reports instead
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
Coverage depends on OpenSanctions dataset — may not include all national PEP lists
From step: PEP Check
Name matching is fuzzy — common names may produce false positives. Birth date strongly recommended for disambiguation.
From step: PEP Check
What to do instead: Provide birth_date parameter for disambiguation
PEP coverage varies by country — major economies and EU members have strong coverage, smaller nations may have gaps
From step: PEP Check
What to do instead: For countries with limited coverage, supplement with local registry checks or use the LLM fallback as a secondary signal
Name matching uses fuzzy logic — common names may produce false positives. Birth date strongly recommended for disambiguation
From step: PEP Check
What to do instead: Always provide birth_date when available to reduce false positives. Verify flagged results against official government records
PEP lists updated multiple times per day — recently appointed officials may take up to 48 hours to appear
From step: PEP Check
What to do instead: For time-sensitive checks on recently appointed officials, cross-reference with news sources
AI-classified results — may miss subtle risk signals or produce false positives
From step: Adverse Media Check
Limited to publicly indexed web content — paywalled news sources not covered
From step: Adverse Media Check
English-language bias — non-English media coverage may be underrepresented
From step: Adverse Media Check
Recency depends on search index freshness (typically 24-48h delay)
From step: Adverse Media Check
AI-categorized results — may produce false positives for common names or names that appear in unrelated news contexts
From step: Adverse Media Check
What to do instead: Review top articles manually to confirm relevance. Use entity_type parameter to improve precision
Screens 235,000+ sources but paywalled content may not be fully indexed. Non-English language coverage varies by region
From step: Adverse Media Check
What to do instead: For high-stakes screening, supplement with manual searches in local-language news sources
Articles typically appear in near real-time but some sources may have a 24-48 hour indexing delay
From step: Adverse Media Check
What to do instead: For breaking news events, supplement with direct web search
