Published by LSEG.

PremiumGUIAPIInvestigative data & public records

In short

World-Check is LSEG's risk-intelligence database for KYC, sanctions, PEP, and adverse-media screening. The current page is an LSEG page. It does not call the product a Thomson Reuters service. It names three access paths: World-Check One for case management, World-Check On Demand for an API, and World-Check Verify for embedded checks. The page says a match is a prompt for review, not a finding that someone poses a risk. No price is printed. A World-Check row is a screening lead.

Product pricing strategy

Premium

The World-Check page does not print a price for One, On Demand, or Verify. It offers a request-details form and regional phone numbers, including a U.S. toll-free number, +1 800 427 7570. Do not quote a Thomson Reuters CLEAR plan as a World-Check price. Ask LSEG which of the three products the contract is, and keep the name.

Utility and features

The LSEG World-Check page, opened on 16 Oct 2026, describes structured records from public-domain sources: sanctions, law and regulatory enforcement, politically exposed persons, relatives and close associates, state-owned enterprises, and adverse media. It says inclusion does not mean the person or organization poses a risk. Customers review matches and decide.

The publisher on the page is LSEG. The screening page is branded LSEG World-Check. It does not say Thomson Reuters.
Three ways in. One is the case platform, On Demand is the API, and Verify is the embedded check.
A match is not a risk finding. The FAQ says inclusion does not mean the person or organization poses a risk.

The FAQ on that page separates the products. World-Check One is the screening and case-management platform. World-Check On Demand is the API. World-Check Verify is low-latency screening for onboarding and payments. Active Intelligence is the name the page gives the AI-enabled layer, and it says human oversight stays in the process. Access is a request-details form, plus regional phone numbers. No dollar price is printed. Thomson Reuters CLEAR is a different company and a different product. Do not file a World-Check hit as a CLEAR record.

1
Name the product, One, On Demand, or Verify, before you describe how the team will screen.
2
Review a possible match against the source information the record includes. Do not stop at the name hit.
3
Keep allegation, investigation, charge, and conviction distinct if the record does.
4
Do not describe World-Check as a Thomson Reuters login. The page you are citing is LSEG's.

Caveats

The page is explicit that a World-Check record is not a verdict. Sanctions, PEP status, and adverse media are different kinds of information, and the page says research is supposed to distinguish allegations from charges and convictions. A possible match still has to be reviewed against your policy.

Active Intelligence does not remove that review. The page says human oversight remains. This listing did not open World-Check One, so it does not describe the case screen. World-Check is not a U.S. public-records skip-trace tool. Use CLEAR, Accurint, or TruLookup when the question is an address or a phone.

Potential use cases

Name the product before the quote. The LSEG page separates World-Check One, the screening and case-management platform, from World-Check On Demand, the API, and World-Check Verify, the low-latency check for onboarding and payments. No dollar price is printed. The U.S. toll-free number on the page is +1 800 427 7570. Access is a request-details form. Do not quote a Thomson Reuters CLEAR plan as a World-Check price. The page you are citing is LSEG's.
A possible match is about to be briefed as a finding that the person poses a risk. The FAQ says inclusion does not mean that. Sanctions, enforcement, PEP status, relatives and close associates, state-owned enterprises, and adverse media are different kinds of information. Read which kind the record is. The page says research should distinguish allegations, investigations, charges, and convictions. Keep those words if the record does.
Someone files the hit under Thomson Reuters because an older memo says World-Check lived there. The page opened on 16 Oct 2026 is branded LSEG. CLEAR is the Thomson Reuters investigation workspace, and it answers a different question. Babel Street says its matching is used inside World-Check One. That component relationship is not a Babel Street login. Active Intelligence, the page's AI layer, still leaves human review in place.

Hard cases

The case where the first result is easy to over-read.

A PEP match is written as guilt

The FAQ's sentence is the one to put in the note: inclusion is not a statement that the person or organization poses a risk. Write the record type, the source information the record includes, and the decision your policy requires a person to make. Do not stop at the name hit. This listing did not open World-Check One, so it does not describe the case screen. If the question is a U.S. address or phone, use CLEAR, Accurint, or TruLookup instead.

Questions

Is World-Check free?

The LSEG page does not show a free tier or a price. Access is a sales request for One, On Demand, or Verify.

Is World-Check still a Thomson Reuters product?

The page opened on 16 Oct 2026 is published by LSEG. It does not describe World-Check as a Thomson Reuters product. CLEAR is the Thomson Reuters investigation workspace.
