What is FIU registration?
FIU registration means registering with a country's Financial Intelligence Unit - the authority receiving suspicious-activity reports - as an obliged AML entity. For crypto companies it was the entry-level compliance status in many countries (Estonia's FIU license being the best-known), now largely superseded in the EU by MiCA authorisation.
What an FIU actually is
Every FATF-aligned country runs an FIU: the national agency collecting suspicious transaction reports (STRs/SARs) from banks, and - since crypto entered AML scope - from VASPs. Examples: FinCEN (US), Estonia's Rahapesu Andmebüroo, Poland's GIIF. Registration makes your company an 'obliged entity': you must run KYC, monitor transactions, appoint an AML officer, and file reports. FIU registration is an AML status, not a full financial license - a distinction banks understand and founders often oversell.
The Estonian era and what replaced it
From 2017 Estonia's FIU licensed over a thousand crypto companies cheaply, making it the default EU flag for exchanges and wallets. Tightening from 2020 onward (capital requirements, local substance, management residency) culled most of them, and the MiCA CASP regime has now replaced national FIU-style licensing across the EU. The lesson carried into today's regime: registrations acquired without substance get revoked in cleanups, and the compliance file - not the certificate - is what survives regulatory scrutiny.
Where FIU-style registration still matters
Outside the EU, many jurisdictions still run registration-based regimes for VASPs: examples include Canada (FINTRAC MSB registration), Poland's pre-MiCA VASP register during transition, and various offshore centres. Even fully licensed CASPs remain obliged entities reporting to the local FIU - authorisation and FIU reporting coexist. When comparing jurisdictions, check what the 'crypto license' actually is: a supervised authorisation with capital and audits, or a filing in an AML register. Banks price the difference.
Frequently asked questions
Is an FIU registration the same as a crypto license?
No. FIU registration is an AML-obliged-entity status - often marketed as a 'license' but without the capital, governance, and supervision of a full authorisation like MiCA CASP. Counterparties and banks distinguish sharply between the two.
Do I still need FIU involvement after getting a MiCA license?
Yes. CASP authorisation makes you a supervised entity, and you still file suspicious-activity reports to the national FIU and maintain the full AML program. The FIU relationship is ongoing, not a one-time registration.
