It depends on your carrier. If your carrier is a CDMA legacy carrier such as Sprint or Verizon, to block on a per call basis, you'll need to dial a code before the number (*67 for Verizon). If your carrier is pretty much anyone else, you should find the settings in Settings>Phone.

If you want to permanently disable your number from showing, contact your carrier.
