The states may have any number of activities or dollar thresholds that require licensure of non bank financial institutions at the state level. The Florida Money Transmitters Code,
FSA Chapter 560, describes Florida licensure requirements.
Each set of requirements stands on its own; activities that might require federal registration may not require state licensure and activities that require state licensure may not require federal registration.
It is wrong to assume that all registered MSBs must also be licensed by the state.
