33 Thomas Street (formerly the AT&T Long Lines Building) is a 550-foot-tall (170 m) windowless skyscraper in the Tribeca neighborhood of Lower Manhattan in New York City, New York, United States. It stands on the east side of Church Street, between Thomas Street and Worth Street. Designed in the Brutalist architectural style, it is a telephone exchange or wire center building which contained three major 4ESS switches used for interexchange (long distance) telephony, as well as a number of other switches used for competitive local exchange carrier services. However, it is not used for incumbent local exchange carrier services, and is not a central office.

The CLLI code for this facility is NYCMNYBW. The Intercept reported that the building is a National Security Agency (NSA) mass surveillance hub code-named TITANPOINTE.^[1]^[2]
