GREENSBORO prefixes in area code 336
NANPA records 188 assigned NXX blocks to rate center GREENSBORO in area code 336, 24.0% of the 783 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. 27 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (65), SUNCOM DBA T-MOBILE USA (24), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (23). The earliest assignment on record here is 2001-01-30 and the most recent 2024-03-11. 118 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 codes 334, 410, 448, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
