Per-Call Blocking allows you to block your number, on a call by call basis, from appearing on the caller identification (ID) unit of the person you are calling, free of charge.

To block your number from displaying on a caller ID unit:
  1. At the dial tone, push *67.
  2. Listen for a series of tones, followed by a dial tone for blocking to be activated.
  3. Make your call as usual.

Repeat these steps for each call you wish to block your number from displaying on a caller ID unit.
