Radio

So you are driving down the road listening to your favorite radio station when you are hit with a 10-minute block of various commercials.  Each commercial having it’s own identifying statement, physical address, phone number, website, etc…. Problem is that you heard one that offered a service that you want.  Who is honestly going to remember a seven to 10 digit phone number or a website name that includes "forward-slash" when you type it in ?  Apply a simple five-digit adminder code to the beginning and end of your ads and problem solved.
