Data sources & methodology
Last updated: June 2026
Entity Ledger aggregates publicly available information about legal entities and individuals from lawful primary sources — company registries, sanctions lists, regulatory and court records — and computes risk signals on top of it. We track over 37 million entities, with depth in the United Kingdom and Cyprus and global coverage of sanctions and politically-exposed persons. This page documents exactly where the data comes from and how we process it.
Sources
| Source | Provides | Updated |
|---|---|---|
| UK Companies House | UK company registrations, officers/directors, persons with significant control (beneficial ownership), insolvency events. | Daily / monthly bulk |
| Cyprus Registrar of Companies | Cyprus company registrations, officers, shareholders and company status. | Periodic |
| Cyprus Government Gazette | Official notices — court-ordered liquidations, dissolutions and regulatory actions. | Ongoing |
| OpenSanctions | Consolidated global sanctions (OFAC, the EU, the UK/OFSI, the UN, Switzerland/SECO and others), politically-exposed persons, and ICIJ offshore-leaks data. | Daily |
| GLEIF | Legal Entity Identifiers (LEI) for cross-border entity identification. | Periodic |
How we process it
Primary sources, preserved. We store each source record in both its raw and a normalized form, and never overwrite original facts — derived signals are layered on top, not in place of, the source data.
Entity resolution. Records are linked primarily on stable registration identifiers. Where a match relies on a name, we accept it only when a second attribute corroborates it (jurisdiction for companies, date of birth for individuals); ambiguous matches are skipped rather than asserted. We do not perform name-only matching, which is the main source of false positives in this kind of data.
Explainable signals. Risk signals — sanctions, PEP status, regulatory and court actions, disqualifications, insolvency — are computed, and each one is traceable to the underlying source record and issuing authority. Sanctions are classified by the designating authority, so an entry is only labelled a "sanction" when it comes from a recognised sanctions programme (rather than, say, a regulatory or maritime action). There are no black-box scores: every signal can be inspected back to its source.
Change tracking. Material changes to an entity — new signals, status changes, ownership and officer changes — are recorded over time, so a profile reflects not just the current state but how it got there.
Accuracy & limitations
All data is derived from lawful public sources and is provided for due-diligence and research purposes. Coverage and freshness vary by source and jurisdiction, and entries reflect the source data at the time it was retrieved. Entity Ledger is not a credit-reference agency and does not provide legal advice; records should be corroborated against primary sources before any decision. If you believe a record is inaccurate, please get in touch — we welcome corrections.
