TRIANGLE prefixes in area code 571
NANPA records 15 assigned NXX blocks to rate center TRIANGLE in area code 571, 2.3% of the 639 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 10 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (3), METROPCS, INC. (2), CORETEL VIRGINIA, LLC - VA (2). The earliest assignment on record here is 2006-01-26 and the most recent 2025-03-14. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 703 – overlay codes cover the same geography, so a rate center is served by all of them.
