About WhoWiki

Free AML and verification tools, built for the businesses big vendors skip

WhoWiki puts sanctions screening, PEP checks, and company verification in front of everyone, free to start, with the source and date on every result. No sales call. No six-figure contract.

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

In one line

WhoWiki is a free web toolkit for anti-money-laundering checks and business verification. Screen a name against global sanctions and PEP lists, check a company, and validate an IBAN, VAT, or LEI number, without signing up. Single checks are free. Bulk screening, monitoring, audit reports, and the API are paid.

Why WhoWiki exists

A basic check shouldn't need a sales team

Run a sanctions check as a two-person startup and you hit a wall. The tool sits behind a "book a demo" button, then a call with an account manager, then a contract priced for a bank. A solo developer trying to add screening before launch runs into the same wall.

The checks themselves are not complicated. Screening a name against a public sanctions list is a lookup against government data that anyone can download. Charging thousands for access to that data, and putting it behind sales, is what keeps small firms out.

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 dollars, is laundered each year. The firms meant to catch it include thousands of small businesses that cannot afford enterprise software. Source: UNODC, Money-Laundering estimates

We built WhoWiki so a founder, an MLRO at a three-person law firm, or a developer building a marketplace can run the same core checks a bank runs, for free, and understand the result.

How it works

Why the tools are free, and how we keep the lights on

Honesty about money matters when the product is free. Here is the whole model.

01 · FREE FOREVER

Single checks cost you nothing

Screen a name, check a company, validate an IBAN or VAT number, and read the glossary. No account, no card, no limit on one-off checks.

02 · PAID FOR SCALE

We charge when you need automation

Bulk and batch screening, ongoing monitoring, audit-ready PDF reports, and API access are paid. That revenue funds the free tools.

03 · PUBLIC DATA

The lists are public. We do the cleaning

Sanctions and PEP data come from government sources. Our work is collecting it, matching names, removing duplicates, and keeping it current.

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 you can check our work.

What we stand for

Four rules we hold ourselves to

Open access

Every core check is free to run, with no signup and no gate in front of a public list.

Sourced results

We name the list and the date behind every answer, so you can verify it yourself.

Plain language

No jargon walls. A glossary explains the terms, and a working tool sits behind each one.

Honest limits

We tell you what the tools can't do, so you know when a check needs a closer look.

What WhoWiki is not

Our free tools give indicative results to help you check quickly and decide what needs a closer look. They are not a full regulated screening system, and they are not legal advice. For formal AML obligations you still need documented procedures and, for many regulated firms, a monitored commercial system with case management and audit trails. Our paid tier covers part of that. The rest is on you and your advisers. If a result matters, verify it against the official source before you act.

Common questions

What people ask about WhoWiki

Is WhoWiki really free?
Yes. Single sanctions and PEP checks, company and IBAN, VAT, and LEI lookups, and the glossary are free with no signup. You only pay if you need bulk screening, ongoing monitoring, audit-ready reports, or API access.
Where does WhoWiki's data come from?
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. We show the source and the date on every result.
Can I use WhoWiki for official AML compliance?
Use it as a fast first check and a research tool. For formal AML obligations you still need documented procedures and, for many regulated firms, a monitored commercial system. WhoWiki gives indicative results, not a substitute for regulated screening or legal advice.
How does WhoWiki make money if the tools are free?
Through a paid tier for teams that need automation, including bulk screening, monitoring, PDF audit reports, and API access, plus advertising on high-traffic utility pages. The data is public. We charge for the service around it.
Is WhoWiki safe to use?
Your checks run without an account. [State your query-logging position here, for example: we do not store the content of your searches. Link to /security/.] We explain exactly what we collect on the Security page.
Who is behind WhoWiki?
WhoWiki is built by [company or team name, and one line on who you are and why you built it]. [Add a founder name and a short, real credential to strengthen trust.]
