Is Caller ID legal?

Yes, it is. Contact your local phone company if you want to subscribe.  You may also block your service, completely or selectively, so that your number isnít released to consumers who subscribe to Caller ID.  For answers to all your blocking questions, contact your local telephone company.  If you have concerns or complaints that are not resolved by the phone company, you may contact the Consumer Affairs Branch
