Canonical page: https://entitybind.com/glossary/last-confirmed Last updated: 2026-10-15 Glossary · Data, licence and time ## How to read this The definition as the field writes it comes first, weaknesses and all. What Entity Bind does about it comes last, in its own paragraph, so you can take one without the other. [Filed under data, licence and time](https://entitybind.com/glossary#data). By [James Rooney](https://entitybind.com/about), founder of Entity Bind · Last revised 15 October 2026 ## What last confirmed means Last confirmed is the most recent time a fact was observed still to hold. It is the field a consumer should read before relying on a value for a decision with consequences, because a fact confirmed this morning and a fact last seen in 2023 look identical unless the store records when each was last observed. It is a weaker claim than truth. A fact confirmed last week may have changed since; the field says what was observed and when, not what is the case now. It is also distinct from a re-read: a source read again and found unchanged confirms the fact, while a source read again and found different ends one period and opens another. Confirmation counts should distinguish repeated sightings from independent corroboration. Three reads of the same register are one source agreeing with itself; a register, a filing and a company's own website agreeing are three. Collapsing them into one counter overstates the evidence. Entity Bind carries a last-checked timestamp and a confirmation count on every fact, keeps same-source re-confirmations separable from independent ones, and ranks survivorship on last confirmed. One thing it does not do is revalidate on a cadence: nothing is refreshed on a schedule, so a fact's freshness is the freshness of the last time a request or a snapshot happened to touch it, and the timestamp on the record states when that was rather than promising currency. ## Where this shows up in Entity Bind Three pages where this term stops being vocabulary and starts changing an answer, a payload or a price. - [Register coverage](https://entitybind.com/coverage): The registers the resolver reads, the licence each one publishes under, and how often a live entity's name is unique once it is tidied to a common form. - [The API reference](https://entitybind.com/api): The REST surface: payloads, the decision outcomes, the error model, the usage block and the ceiling on the confidence field. - [Reference data](https://entitybind.com/use-cases/reference-data): Identifier crosswalks, where each fact came from, and what a cited fact has to carry to be usable downstream. The fastest way past a definition is a file: which of your rows are the same company, which of your existing matches we would not have made, and what we could not decide.

Explicitly not a screening, scoring or eligibility tool. - [KYC and onboarding](https://entitybind.com/use-cases/kyc-and-onboarding) (Use case): Counterparty identity with a receipt that survives seven years. ## The other 6 terms on this shelf Facts have owners and dates. What may be stored, what may only be passed through, and what a date on a fact actually asserts. - [Licence tier](https://entitybind.com/glossary/licence-tier) - [Pass-through data](https://entitybind.com/glossary/pass-through-data) - [Temporal facts](https://entitybind.com/glossary/temporal-facts) - [First seen](https://entitybind.com/glossary/first-seen) - [PSC (person with significant control)](https://entitybind.com/glossary/psc) - [Beneficial ownership](https://entitybind.com/glossary/beneficial-ownership) Previous, alphabetically: [Jaro–Winkler](https://entitybind.com/glossary/jaro-winkler) · Next, alphabetically: [LEI (Legal Entity Identifier)](https://entitybind.com/glossary/lei) ## Evidence basis Internal fixtures only. The historical 2026-08-29 per-tier recording covers 317 GB companies with identifier-rich arrivals seeding the catalogue first; the context tier includes country and registered-town prose. Its legacy replay has no full-prompt-verified calls and cannot certify current calibration. The September 5 CI reports cover 1,176 labelled pairs and 705 records over 250 companies using offline stubs. These are not independent customer holdouts or live production validation; the 99% minimum-input product target remains unmet.
