Under the SAFE Act, (Federal requirements, Regulation G), NMLS reps must include their unique identifer on any written communication (12 CFR 1007.105(b)(3))

If the bank wishes to do a mortgage directmail compaign, and not include a NMLS ID, is that acceptable?

i.e. it comes from the President of the Bank, who is not NMLS licensed. Or it comes from "the bank" and not a particular individual?

NMLS number does not have to be on advertising materials.

Agree. Also, just for the record, Reg. G doesn't say "any" written communication, it says the "initial" written communication.
