Answer 1

Answer 2

Where blocking is applied on a call-by-call basis (at the time a call is made), subscribers can block -- prevent their numbers from being displayed -- by dialing a special code before making a call. In North America and some other regions, the code is *67, while the United Kingdom and Ireland use 141. This special code does not block the information from companies using call capture technology. This means that equipment with caller ID will simply display the word 'PRIVATE' or 'WITHHELD'. When CNID is blocked at the caller's request, the number is actually transmitted through the entire telephone network, with the 'Presentation Withheld' flag set; the destination CO is expected to honor this flag, but sometimes does not -- especially when the destination phone number is served by an ISDN primary rate interface.

Alternatively, in cases where caller ID is being blocked automatically, it can only be released on a call-by-call basis by dialing a special code (*82 in the U.S.; 1470 in the UK). See Disabling, below.

Similarly, some countries offer anonymous caller rejection, which rejects all calls when the subscriber's number is blocked. Some telephone companies also route anonymous calls to a service which requires the caller to announce him or herself, and then requires the called party to accept or reject the call. Blocking the number is referred to as Calling Line Identification Restriction (CLIR). Emergency services will most likely be able to show the restricted number using a service called Calling Line Identification Restriction Override (CLIRO), or by using general ANI services.

In the United States, caller ID blocking does not disable the ANI transmission of your telephone number. ANI equipment is typically found at large companies, call centers, and law enforcement stations. ANI transmissions are more difficult to block or spoof than caller ID.
