When to put license number in calling card

QUESTION: Sir John, should we always, at all times, put our Broker license number in our calling cards?

ANSWER: YES, when and only when your calling card says you are a Real Estate Broker. However, if you have other calling cards for your other affairs such as Political Campaigner, Family Counselor, Dog Trainer, Funeral Parlor Agent, Insurance Agent, Real Estate Referral Agent, Condominium Administrator, etc that does not mention "BROKER", then you don't need to put your Broker License Number (stupid question).
