Restrict Caller ID is a restriction that is placed on your account to completely
block your information (name and phone number) from being displayed on any call you make. Visit www.sprint.com
and log in to your account to view and change personal settings.
Block Caller ID by dialing *67 before the number you're calling. This only affects one call at a time, so you have to dial the code before every call you want to block your Caller ID.
