World-Check One: screening, login and API explained

Q: Can I screen against Australia’s own sanctions list?

AUSTRAC points reporting entities to DFAT ’s Consolidated List for Australian sanctions designations. If you use World-Check One, check that its sanctions coverage includes that list, and keep the result. Our sanctions screening guide explains the rules.

World-Check One is LSEG’s platform for screening customers against World-Check data on sanctions, PEPs, enforcement and adverse media. You open a case, screen the name, then resolve each possible match with a logged decision. Subscribers sign in at risk.lseg.com, and a separately licensed REST API brings the same screening into your own systems.

This guide is for compliance teams that use, or are weighing up, World-Check One for client screening. Product facts come from LSEG’s own pages and fact sheets, and Australian rules from the Australian Transaction Reports and Analysis Centre (AUSTRAC), checked on 21 October 2026.

In brief

What it is: LSEG’s platform for screening customers against World-Check data on sanctions, politically exposed persons (PEPs), law and regulatory enforcement and adverse media.
How it works: you open a case, screen the name with secondary identifiers, then review and resolve each possible match. Every action is logged and date-stamped.
Login: subscribers sign in at risk.lseg.com. Your administrator sets up users, groups and roles.
Integration: the World-Check One application programming interface (API) is a REST and JSON service over HTTPS, licensed separately, authenticated with API keys and tested on a pilot account first.
In Australia: a screening tool does not replace your customer due diligence. AUSTRAC still expects sanctions checks before the service and during the relationship.

What is World-Check One?

World-Check One is LSEG’s screening platform. LSEG describes it as a know your customer (KYC) verification and customer screening platform that brings World-Check data and screening software together. You may still see it sold or searched for under its former Refinitiv name.

The platform screens names against the World-Check database. That database covers sanctions, PEPs, law and regulatory enforcement and relevant adverse media. What the database holds, and the other ways to buy it, is covered in our guide to World-Check Risk Intelligence.

Around the screening, World-Check One adds case management, batch screening, ongoing rescreening and a date-stamped audit trail. Optional features include Media Check for adverse media, UBO Check for beneficial ownership and Watchlist Screening for your own lists.

Key point

Under Australia’s AML/CTF Act, a reporting entity must establish whether a customer is designated for targeted financial sanctions before providing a designated service.

Terms in this section

KYC: Know your customer. Confirming a customer is who they say they are and understanding the risk they bring.
UBO: Ultimate beneficial owner. The individual who ultimately owns or controls a customer that is a company, trust or other entity.
AML/CTF: Anti-money laundering and counter-terrorism financing. The Australian regime, run by AUSTRAC under the AML/CTF Act 2006, that requires regulated businesses to detect and report money laundering and terrorism financing.

How does a World-Check One screening case run?

How a World-Check One screening case runs

From a name to a recorded decision

Step 1
Create the case

The name plus secondary identifiers, such as date of birth, nationality or an ID number.
Step 2
Screen against World-Check

All source types, or selected ones such as sanctions only.
Step 3
Review possible matches

Each match side by side with your customer record.
Step 4
Resolve and record

A status, a risk level and notes. Every action is logged and date-stamped.
Ongoing screening

Clients you keep are rescreened, so a new listing raises an alert.

World-Check One finds possible matches; your team resolves each one and the platform keeps the record. Ongoing screening re-checks the clients you keep.

Every check starts as a case. You enter the name and any secondary identifiers, such as date of birth, gender, nationality or an ID number. LSEG says these identifiers help reduce false positives.

The matching engine then compares the case with World-Check. You can screen against all source types or selected ones, such as sanctions only. Name matching allows for spelling variations and names in other languages.

Your team reviews each possible match side by side with the customer record and resolves it with a status, a risk level and notes. The decision stays yours: World-Check One records it, it does not make it. For how to weigh a match, see our AML risk assessment methodology.

The practical facts a new World-Check One user looks up: where to sign in, how online packages work, how the API is accessed and how long certification takes.

Subscribers sign in at risk.lseg.com. Your organisation’s administrator sets up users, groups and roles, so ask them first if your login fails. Existing customers get product support through the LSEG support portal.

Give each person their own login rather than sharing one. The audit trail logs and date-stamps every action, which only proves who decided what if each user is a named person.

LSEG also sells World-Check One online in packages of usage points. Each package covers up to 3 users, and its points last 12 months from purchase and do not carry over.

How does the World-Check One API work?

The World-Check One API is a REST and JSON web service, available only over HTTPS. It lets your own system or customer relationship management (CRM) create cases, screen names and pull back possible matches without anyone opening the portal.

The API is licensed separately: LSEG says access has to be enabled through product licensing. You authenticate with a set of API keys. With a pilot account you build and test first, and moving to production only means swapping the keys.

The API covers more than single checks:

case management calls to review and resolve matches, with the audit trail
client watchlists, to screen against your own lists
webhooks that push case updates to your system
optional Media Check and ultimate beneficial owner (UBO) data

A separate Zero Footprint Screening API runs single name checks with nothing stored by LSEG. It has no tracking, no ongoing screening and no batch upload, so it suits one-off payments rather than client onboarding.

What training and certification is there?

LSEG runs a World-Check One certification in its Learning Centre. It covers seven subjects and takes 2 to 4 hours, with a final exam and a certificate.

There are three pathways: Administrator, Case Management Screener and Zero Footprint Screener. LSEG says the Learning Centre is free for customers and prospective customers. Registration needs a work or student email address.

What does World-Check One not do for you?

A screening tool supports your customer due diligence; it is not the whole of it. A clear result means the name did not match World-Check when you checked, nothing more.

You still verify who the customer is, rate their risk and keep checking during the relationship. AUSTRAC requires you to check for sanctions designations during the relationship too, so switch on ongoing screening for clients you keep. Our customer due diligence checklist sets out the rest.

Frequently asked questions

Is World-Check One the same as Refinitiv World-Check?

Yes. World-Check is now an LSEG product, and LSEG sells the platform as LSEG World-Check One. Older documents and searches still use the Refinitiv name.

How often is World-Check data updated?

LSEG says World-Check data is updated daily.

Can I screen against Australia’s own sanctions list?

AUSTRAC points reporting entities to DFAT’s Consolidated List for Australian sanctions designations. If you use World-Check One, check that its sanctions coverage includes that list, and keep the result. Our sanctions screening guide explains the rules.

Next steps

If your team screens clients in World-Check One and then copies the result into another system, the record is split across two places.

StackGo’s IdentityCheck runs identity verification and PEP and sanctions screening inside the CRM or practice software you already use, through our Screen workflow. See how IdentityCheck supports AUSTRAC Tranche 2 compliance.
