ANAC) Automatic number announcement circuit (ANAC) is a special 10 telephone number that is meant to be used by 11 phone company technicians and other telecommunications technicians to determine the phone number of a particular line. The way ANAC works is fairly simple: A technician will call a local ANAC's phone number (in Connecticut, they would dial 970) this number connects to a computer at a local 12 central office which uses a voice synthesizer or digital samples to "speak" the phone number of the line calling in. The main purpose of this system is to allow phone company technicians to identify which telephone line they are connected to. Because this system is meant for phone company technicians, the ANAC system works with unlisted and even numbers with 13 caller ID blocking. Some ANACs are very regional or local in scope, while others are state or 14 area code-wide. There appears to be no national cohesive system for them. Every telephone company (big or small) can determine its own ANAC for each individual central office, leading to a mish-mash of overlapping and/or spotty coverage. Some large telephone companies have toll-free numbers set-up, but these numbers remain undisclosed to prevent abusive use. There are some private national toll-free numbers that use 15 automatic number identification and then have a computer read back the number that is calling, but these are not intended for use in identifying your phone number, they are used in order for you to confirm the phone you are calling from so that a computer can automatically pull up your account for the next available customer service representative. However, if one were to call up one of these numbers, listen for the number confirmation and hang up, they would in effect be using this system as if it were an ANAC. In some regions, there are several numbers depending on the telephone company and/or the area you are calling from as there can be several central offices serving some areas.
