I don't know if I really see what kind of safety withholding your last name provides. If you have an unlisted number it will be difficult to make prank or threatenning calls, but if someone really wants to hurt you it won't be hard. They know where you work. I'm not trying to sound pessimistic, but all a nut would have to do is wait for you outside the hospital follow you home. No one needs a last name to do that.
There are many websites that list UNLISTED phone numbers! I know firsthand since I have a membership to one. But, you need a last name to look it up. You cannot do anything with just a first name.
When you request your number to be unlisted thru the phone company, it will not be published in the phone book or when you call directory assistance (I used to work for the phone co). But, if you fill out any forms and put down your phone number, it can somehow end up on the internet thanks to companies who sell your info.
I am not worried about someone waiting outside the hospital to hurt me because we have big burly security to walk us to our cars. However, I don't have a huge security guard in my home waiting to protect me from a nut waiting outside my home.
If you have ever had someone stalk you...you would totally understand the fear it throws into your life! It's the worst thing ever!
