Q: My name is John Johnson but everyone calls me Johnny. May I use Johnny in my advertising? How about my business cards and sign? 

A: Business cards and signs are considered advertising. The recommended way to use a nickname in advertising is to include it in quotation marks after your first name or first initial. For example: John “Johnny” Johnson or J. “Johnny” Johnson. And any time you use your first name or nickname in any advertising, you must also use your last name as it is registered with the Florida Real Estate Commission.
