FinCEN MSB Registrant Search: How to Use the Public Database

FinCEN maintains a public, searchable database of registered Money Services Businesses. This database — called the MSB Registrant Search — allows anyone to look up whether a specific business is registered as an MSB with FinCEN and what MSB activities it is registered for.

Understanding how to use this tool matters for fintechs that need to verify their own registration, for businesses conducting due diligence on partners and counterparties, and for understanding how regulators and sponsors use this database to verify compliance.

Where to Find the MSB Registrant Search

The FinCEN MSB Registrant Search is available at fincen.gov. Search for "MSB registrant search" on the FinCEN website or navigate directly to the MSB section. The tool is publicly available and requires no login or account.

What You Can Search For

The MSB Registrant Search allows you to search by business name, by EIN, or by a combination of both. Results show businesses whose registrations match the search criteria.

What the Search Results Show

For each matching business, the search results display the business's legal name, its principal place of business address, the MSB activity categories it is registered for, the date its most recent registration or re-registration became effective, and whether the registration is currently active.

The database does not show all historical registration information — it reflects the most current registration information on file.

What the Database Does NOT Show

The MSB registrant database does not show whether a business is compliant with BSA/AML requirements — only whether it is registered. A registered MSB may have an inadequate compliance program or may be subject to regulatory action. Registration status is a threshold requirement, not a compliance certification.

The database does not show state money transmitter license status. Federal FinCEN registration and state licensing are separate systems maintained by separate regulatory bodies.

Why This Database Matters for Fintechs

Verifying Your Own Registration

After completing FinCEN MSB registration, fintechs should search for their own business in the database to confirm their registration appears correctly. This verification confirms that the registration was processed and is visible to regulators and partners.

Sponsor Bank Verification

Sponsor banks routinely check the FinCEN MSB registrant database to verify that their fintech partners are properly registered. A fintech that does not appear in the database will face questions from its sponsor bank that could delay or complicate the banking relationship.

Due Diligence on Counterparties

For businesses that work with other MSBs — as agents, sub-processors, or partners — the FinCEN MSB registrant database provides a quick way to verify whether a counterparty is registered as required. Doing business with an unregistered MSB creates compliance risk.

Regulatory and Law Enforcement Use

FinCEN and law enforcement agencies use the MSB registrant database as one tool in identifying and investigating unlicensed or unregistered money services businesses. Being registered and appearing correctly in the database is a basic compliance baseline.

Frequently Asked Questions

How quickly does registration appear in the database after I submit?

Registration typically appears in the public database within a few business days of submission. If your business does not appear after a week, contact FinCEN through the contact information on the BSA E-Filing website to confirm your submission was received.

What if my business information has changed since I registered?

Your current registration information in the database reflects your most recent registration or re-registration. If your business name, address, or activities have changed significantly, update your information at your next two-year re-registration. For major ownership or activity changes, consider reflecting them in your registration promptly.

Can I search for someone else's MSB registration?

Yes. The FinCEN MSB registrant database is publicly available and can be searched by anyone. This is by design — transparency about who is operating as a registered MSB is part of the regulatory framework's consumer protection and law enforcement functions.
