This map shows wire-center / zone geometry from CHNLSYNC’s copper-retirement file. It is not confirmation that a street address is cut.

An AT&T copper retirement letter is notice that AT&T filed to discontinue legacy voice in portions of listed wire centers. Only AT&T can confirm an address (business 855-235-0900, residential 800-288-2020).

CHNLSYNC is a broker — not a carrier — and cannot stop a disconnect. Technical authority for fire and elevator lines stays with the monitoring company, licensed vendor, and AHJ.
