Automated Number Announcement Circuit (ANAC) Numbers


An Automated Number Announcement Circuit or ANAC is a voice POTS (Plain Old Telephone System) or VoIP resource, usually provided by carriers although there are a number of privately hosted services, that vocalizes the telephone number you called it from. Some ANAC numbers only work when you are calling them from the same carrier that provides them and will error out if you attempt to call from another provider's system. ANACs are essential assets for fone phreaking. I use them frequently enough - and the Wikipedia article that used to list several keeps getting whittled down due to WP:DIRECTORY violations - that I'm starting a living list of them here. If you have any ANAC numbers you would like to share please join us on Telegram or on Discord and drop me a line (pun intended).

Included at the bottom of the list are some toll free numbers; it should be noted that toll-free service is provided on tiers of geographical reach. Some toll free numbers only work in Canada or the United States, a portion of the United States, or both Canada and the United States - so your ability to reach a toll free ANAC may vary based on your location. All of the toll-free numbers have been tested from Ontario, Canada as of December 31, 2023.
