What MiCA passporting actually means
MiCA passporting allows a company authorized as a Crypto-Asset Service Provider, or CASP, in one EU member state to offer the same services across all 27 member states without a separate license in each one.
Before MiCA, digital asset service providers in Europe faced a patchwork of national regimes, each with its own registration process, capital requirements and supervisory expectations.
A CASP authorization now works like the passporting regime banks and payment institutions already use under existing EU financial services law: authorize once with a home-state regulator, notify host-state regulators, and start operating there.
Who qualifies for a MiCA passport
Only entities holding a CASP authorization, or an e-money and asset-referenced token issuer license, from an EU national competent authority qualify. A company registered outside the EU cannot passport in by proxy.
The authorization covers specific services, such as custody, exchange, order execution or portfolio management on digital assets, and the passport only extends to the services actually listed in the home-state license.
A provider licensed only for custody cannot passport an exchange service it does not hold at home; the scope travels with the license, not with the brand.
What to verify before relying on a passported provider
A bank or payment institution evaluating an infrastructure partner should check three things: the home-state authorization is current, the host-state notification for the specific market has actually been filed, and the licensed service scope matches what is being sold.
National competent authorities publish CASP registers; a five-minute check against the home regulator's public register is worth more than a claim on a partner's website.
For an infrastructure provider built to serve banks and payment institutions across multiple EU markets from a single authorization, passporting is what makes a genuinely EU-wide product possible without a license-by-license buildout in every country served.
