According to the reg, a registered MLO shall prodive his or her unique identifier to a consumer;
1. Upon request
2. Before acting as a mortgage loan originator; and
3. Through the originator's initial written communication,
if any, whether or paper or electronically.
Point two may fall under verbal, but I don't believe it is when the MLO answers the phone. Now, if the person calling is asking for a mortgage loan, then, maybe it should be given verbally when the caller begins asking questions about a mortgage loan.
I agree, it's overkill as in Randy's example above.
