About WhoWiki

Primary-source screening, kept current as the lists change

WhoWiki screens names against the OFAC, EU, UN, and UK OFSI sanctions lists and updates as those lists change. Every result shows the source and the date behind it, so your team gets a check that traces straight back to the official record.

Data from OFAC, the EU, the UN, the UK, and other primary government sources, updated as the official lists change.

Know who you’re dealing with. WhoWiki is a screening and business verification service built on primary regulatory sources. Screen a name against global sanctions and PEP lists, verify a company, and validate an IBAN, VAT, or LEI number. Single checks are free to run. Bulk screening, ongoing monitoring, audit-ready reports, and API access are the paid tier.

Why WhoWiki exists

Screening is only as good as it is current

Compliance teams in regulated industries spend much of their time keeping up with change. Sanctions lists move constantly, often daily. A name that was clear last month may not be clear today.

Most screening data reaches firms through resold databases, a step removed from the source and refreshed on someone else’s schedule. WhoWiki builds directly on the primary government lists and updates as they change, so a result reflects the current record and names where it came from.

2–5%of global GDP, every year
The UN Office on Drugs and Crime estimates that 2 to 5 percent of global GDP, up to around $2 trillion, is laundered each year. The firms expected to catch it face sanctions and watchlist changes that arrive without warning. Screening that lags the official lists is a real exposure. Source: UNODC, Money-Laundering estimates

We built WhoWiki so a compliance analyst, an MLRO, or a product team can run a primary-source check in seconds and see exactly where the answer came from.

How it works

Primary sources, kept current, sourced on every result

Three things define how WhoWiki works.

01 · PRIMARY SOURCES

Straight from the official lists

Sanctions and PEP data comes from OFAC, the EU, the UN, the UK, and other government sources. We collect it, match names, and remove duplicates. No resold middle layer.

02 · KEPT CURRENT

Updated as the lists change

When an authority updates a list, our data follows. A result reflects the current record and shows the date it was checked, so nothing rests on a stale copy.

03 · BUILT TO SCALE

From a single check to your whole book

Single checks are free to run. Bulk screening, ongoing monitoring, audit-ready reports, and API access are the paid tier, for teams that screen at volume.

Where our data comes from

Primary sources, shown on every result

We build on official government and open registries, not a resold private database. You see the list and the date behind each answer, so your team and your auditors can trace it to the record.

Source What it covers How current
OFAC US sanctions: SDN and Consolidated lists As OFAC publishes, often daily
EU EU consolidated financial sanctions list As published
UN UN Security Council Consolidated List As published
UK OFSI UK consolidated sanctions list As published
GLEIF Legal Entity Identifiers and ownership Daily
EU VIES EU VAT number validation Checked live
Wikidata Reference data for politically exposed persons Continuous

Every tool shows the source list and the date on the result. When a list updates, our tools use the new version. Full detail is on the data sources page.

Who it’s for

Built for teams that answer to a regulator

BANKING & PAYMENTS

Screening that keeps pace

Sanctions and watchlist changes arrive daily. Run primary-source checks that update as the lists do, and give analysts a fast second look they can trace to the official record.

INSURANCE & LEGAL

Sourced results you can defend

Underwriters, brokers, and law firms carry real AML duties. Every check names the source and the date, so a file stands up when a regulator or auditor asks how it was screened.

COMPLIANCE & PRODUCT TEAMS

Screening you can build on

A clean REST API and audit-ready reports fit checks into your existing process and case management, with no resold data layer in between.

What we stand for

Four rules we hold ourselves to

Primary sources only

Every check runs against the official government list, not a resold copy of it.

Kept current

When an authority updates a list, our data follows, so a result reflects today’s record.

Sourced and dated

We name the list and the date behind every answer, so you can trace it and defend it.

Honest about scope

We tell you what a check does and does not cover, so you know when it needs a closer look.

Where WhoWiki fits alongside your stack

WhoWiki gives your team primary-source checks they can run fast and trace to the record. It is a screening and verification layer, not a full case-management platform, and it is not legal advice. Most regulated firms run it alongside a system of record that handles workflow, alerting, and audit trails. Our paid tier covers ongoing monitoring, audit-ready reports, and API access for teams that need them. Where a result carries weight, confirm it against the official source before you act.

Our approach

The purpose behind WhoWiki

WhoWiki is a screening and business verification service built on primary regulatory sources.

Compliance teams in regulated industries spend much of their time keeping up with change. Sanctions lists move constantly, often daily. WhoWiki screens against the OFAC, EU, UN, and UK OFSI lists and updates as those lists change, so a result reflects the current position, not last month’s. Every check names the source list and the date behind it, which gives teams something they can show an auditor or examiner.

We work with compliance and product leaders in banking, payments, insurance, legal, and other regulated sectors, who need screening that stays current and results they can defend.

Common questions

What compliance teams ask about WhoWiki

Where does WhoWiki’s data come from?
WhoWiki builds on primary government and open sources: OFAC, the EU consolidated list, the UN Security Council list, the UK OFSI list, GLEIF for entity data, and the EU VIES service for VAT. Every result shows the source list and the date behind it.
How current is WhoWiki’s screening data?
WhoWiki updates as the official lists change, often daily. Each result shows the date it was checked, so a screening reflects the current record rather than a stale copy.
Can WhoWiki replace our existing screening system?
WhoWiki is a primary-source screening and verification layer that most regulated firms run alongside a system of record handling workflow, alerting, and audit trails. The paid tier adds bulk screening, ongoing monitoring, audit-ready reports, and API access. It is not a full case-management platform or legal advice.
Does WhoWiki produce records we can show an auditor?
Every check names the source list and the date behind the result. The paid tier adds audit-ready PDF reports and monitoring logs for teams that need a documented record.
Does WhoWiki have an API?
Yes. A REST API is part of the paid tier, with documentation, so compliance and product teams can build sanctions and PEP checks into their own systems.
What does WhoWiki cost?
Single checks are free to run. Bulk screening, ongoing monitoring, audit-ready reports, and API access are the paid tier, priced for teams that screen at volume.

Run a primary-source check

Screen a name or verify a business against the official lists in seconds, and see exactly where the answer came from.

A note on scope. WhoWiki gives primary-source results and runs alongside your existing screening and case-management systems. It is not a substitute for regulated screening, legal, or compliance advice. Confirm a result against the official source before acting on it. Last reviewed August 2026.
