The Importance of Real-Time Company Registry Data for KYB

Live company registry data is company information retrieved in real time, at the point of request, directly from official company registries. Every record is primary-sourced, time-and-date-stamped, and carries the attestation of the registry that issued it. Stored registry data, meanwhile, is a copy of that record, held in a third-party database and refreshed on someone else's schedule. Both serve different use cases. For complex, cross-border or higher-risk entities, live registry data is best. For a sole trader or a single-owner domestic company, a stored copy is usually enough. 

Why does live company registry data matter for KYB? 

Live registry data tells you what the official record says when you make the decision and proves where that record came from. In other words, it has regulatory defensibility. And regulators are no longer satisfied that a check was performed; they want to see the quality of the evidence behind it. Kyckr's analysis of FCA enforcement found that 68% of AML fines issued between 2020 and 2025 involved data failures – that is, outdated, missing, or incomplete evidence. The registry's own record, stamped with the date and time of retrieval, is the strongest form of proof an onboarding file can hold. 

How does a live registry connection work? 

When you ask it to, the connection calls the registry holding the record, retrieves it, structures it and returns it. 

Retrieval happens in one of two ways.

• API. Where the register offers one. It might be a REST API returning JSON or SOAP returning XML. No two are alike. Company registry APIs have different authentication, query rules, field names, and response shapes. A Business Registry Insights survey of 84 countries found 48% of registers offer a public API.

• Direct retrieval. The network queries the register's own search, requests the page or orders the filed document, then extracts the data from what comes back.

Either way, what arrives is raw and shaped by whichever register produced it. One returns shareholdings as a count of shares, the next as a percentage, the third as a share class with no percentage. A director in one jurisdiction is an officer or a gérant in another. Dates, field names and legal forms all differ.

In short, a normalisation layer maps every register's fields to one schema. It is the reason a live connection takes seconds where a cached lookup takes milliseconds.

Is live company registry data reliable? 

Live retrieval guarantees currency and provenance, but it cannot make a bad filing good.

Reliability varies by jurisdiction. The Business Registry Insights 2024 report found that 71.1% now verify filings against other sources like sanctions watchlists and land registries. Kyckr's ranking of the 10 most reliable company registries puts Singapore's ACRA, Estonia's E-Business Register, Companies House and Denmark's CVR at the top because all four verify identities and act on noncompliance. Others lag. Luxembourg's LBR only announced automated verification in December 2025, while, according to Business Registry Insights’ same report, Cyprus doesn’t verify data whatsoever.

Does the law require live company registry data?

No British, American, or European law obliges compliance teams to use live registry connections.

The Financial Action Task Force, which sets the international standard for AML and KYB, recommends, in Recommendation 10, that firms verify company ownership against "reliable, independent" sources. The phrasing rules out two things: customer self-disclosures, which cannot be independent, and stale data, which is not, by definition, reliable for establishing what is true now.

British regulators are moving in the same direction through enforcement rather than rulemaking. The FCA's enforcement actions increasingly turn on what the firm knew, when it knew it, and what evidence it held. 

Do regulators fine banks for stale data? 

Yes, increasingly. In October 2022, the FCA fined Gatehouse Bank for deficient AML defences, one example being that it verified the owners of a special purpose vehicle (SPV) in a high-risk country against a stale list of investors. The FCA fined ADM Investor Services International (ADMISI) in September 2023 for, among other failings, relying on an outdated database of Politically Exposed Persons (PEPs).

As the FCA stated in their Final Notice for ADMISI, the broker relied on outdated information, which meant it “failed to properly assess the money laundering risk” of the customer in question.

A live registry connection means that the onboarding decision is more likely to be backed by the freshest, most reliable evidence available.

Why aren't KYB databases enough?

KYB databases are a copy of the official record, not the record itself. They work well for simple, low-risk customers and poorly for complex ones.

Three problems compound as risk rises.

1. Staleness

Company data starts ageing the moment it is retrieved. A registry is itself a database, so even the official record is a snapshot. But a third-party database adds a second lag: it scrapes or downloads from the registry periodically, so by the time an analyst pulls a profile, the company may have changed its owners, directors, or governing structure. That lag rarely matters for low-risk entities, but it compounds for more complex types.

According to Kyckr’s research, staleness varies among providers and jurisdictions. Dun & Bradstreet updates some datasets daily, others yearly, while Moody’s ownership data is updated weekly.

2. Provenance

Databases draw on hundreds of sources, including business self-declarations, official registries, and other KYB databases. Buy from a vendor that buys from a vendor, and you are looking at a copy of a copy of a copy. The better databases publish an attestation of provenance for every entity. Many do not. Moody’s is transparent about its sourcing. Its own public documentation states that it relies on a mix of official sources, more than 170 third-party vendors, company websites, and financial regulators.

3. Risk sensitivity

A one-week-old company with a single UK owner carries less risk than a multi-jurisdictional company with several owners, several directors, and a layered holding structure. The evidence threshold rises with the risk. So does the cost of relying on a copy.

This is why many global obliged entities run a multi-vendor workflow: enriched databases for low-risk business banking customers, live registry retrieval for moderate and complex ownership structures. Specialist databases such as Sayari also earn their place in high-risk and commercially sensitive cases, where the public record is patchy or obscure.

What are the limits of live company registry data?

Live company registry networks are dependent on the registries they connect to.

1. Availability

A live network depends on registries staying up and staying still. Three things break a connection: the registry changes its API, you change yours, or something unforeseen happens at the registry. The first is usually announced. The second is the dangerous one. As Kyckr's Head of Customer Delivery Andrew Kellett describes it, a registry in a rarely used jurisdiction adds a slash to its registration numbers, your engineers patch the search, and the patch breaks ten other integrations. Fallback procedures per connection handle most of it, and they must be written per registry.

2. Complexity

Registries behave differently, and that is the most consistent thing about them. Companies House has good fuzzy logic: search "hotel", and it returns hundreds of thousands of results without falling over. Italy's Infocamere does not. A developer searching it for "Peroni" broke the search, and the entity's full name returned a clean result in seconds. Australia's ASIC has the opposite problem, sometimes returning a profile so large the call fails.

As Kyckr’s Head of Customer Delivery Andrew Kellett said, “Registries don’t play by the same rules. Each one has its quirks.”

Which should you use?

It depends on your risk appetite, and you probably need both. 

For solo traders and simple domestic companies, a database is faster and cheaper, and the evidence threshold is low enough that a recent copy will hold up. For anything cross-border, multi-owner, layered, or generally complex, use a live connection. The regulator will ask what you knew at the point of onboarding, and only primary-sourced, time-stamped registry data answers that question without argument.

If you take one thing from this: a database gives you a copy of the official record. A live registry connection gives you the record.
