# Money services business (MSB)

A money services business (MSB) is FinCEN’s registration category for nonbank financial businesses — money transmitters, currency exchangers, check cashers, and similar. MSBs must register with FinCEN, maintain a written BSA/AML program, and file the same core reports as banks, including suspicious activity reports. State licensing applies separately.

MSB is the federal umbrella; money transmitter is one activity underneath it. Registration with FinCEN does not substitute for state money transmitter licenses, and vice versa — a transmitting business generally needs both. Virtual-asset businesses matter here too: the US regulates exchanging and transmitting virtual assets largely as MSB activity under FinCEN.

For platforms, the practical question is whether their funds flow triggers the classification at all — it turns on who holds the money, in whose name, and under whose control. Infinite’s third-party funds flow gives every customer their own account at the network’s partner institutions, with documentation your counsel can review in diligence.

## Frequently asked questions

### Is every MSB a money transmitter?

No. Money transmission is one MSB category among several — check cashing, currency exchange, and money orders also qualify, generally above $1,000 per person, per day. Money transmission has no threshold, which is why it is the category most platforms worry about. [Money transmitter](https://infinite.net/learn/glossary/money-transmitter.md)

### Does FinCEN registration replace state licenses?

No. FinCEN registration is federal; money transmission generally also requires a license in each state where the business operates. The two regimes run in parallel, each with its own obligations. [Money transmitter](https://infinite.net/learn/glossary/money-transmitter.md)

### Are stablecoin businesses MSBs?

The US regulates exchanging and transmitting virtual assets largely as MSB activity under FinCEN, but classification turns on who holds and controls the funds — a structural question for counsel. [VASP](https://infinite.net/learn/glossary/vasp.md)
