WINSTN SAL prefixes in area code 743

NANPA records 20 assigned NXX blocks to rate center WINSTN SAL in area code 743, 12.3% of the 163 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. 12 holders hold those blocks, the largest being ONVOY, LLC - NC (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (2), LEVEL 3 COMMUNICATIONS, LLC - NC (2). The earliest assignment on record here is 2016-04-06 and the most recent 2026-10-28. 20 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 336 – overlay codes cover the same geography, so a rate center is served by all of them.
