FAQ
Does Series 66 replace Series 63 and 65?
For dual registration with a valid SIE and Series 7, yes — CRD grants 63 and 65 credit. The 66 is not a single standalone license by itself.
Can I take Series 66 without Series 7?
The Series 7 is a co-requisite. Without it, the 66 does not complete agent + IAR qualification.
