The Federal Communications Commission requires that your cellular number be displayed whenever you make an outbound call. If you place a call to a cellular or wireline telephone equipped with Caller ID, your cellular number will be displayed.

However, you can block the display of your cellular number in either of two ways.

• Per call blocking lets you block the transmission of your cellular number prior to each outbound call. Simply dial *67 + the number you are calling + SEND.
  
• Per line blocking lets you block the transmission of your cellular number on all outbound calls. You can unblock your cellular number on a per call basis by dialing *82 + the number you are calling + SEND.
  

Your local carrier may apply additional charges for these features, depending upon your home location, and normal airtime and other charges apply. In addition, some states do not allow per line blocking, which must be requested from your local carrier.

When roaming outside your home area, please be aware that some areas do not support call blocking. Contact your local carrier's customer service (611 or *611 from your cellular phone) or the Federal Wireless Service Center (1-888-333-9473) for assistance.
