The former AT&T Long Lines Building at 33 Thomas Street is a 550-foot (167.5 meters) tall skyscraper in the Borough of Manhattan, New York, United States. It stands on the east side of Church Street, between Thomas and Worth Streets.
The building is a telephone exchange or wire center building which contained three major switches used for interexchange (long distance) telephony, two owned by AT&T and one formerly owned by Verizon (decommissioned in 2009). The building is reportedly home to a National Security Agency surveillance facility named TITANPOINTE.
