BURLINGTON prefixes in area code 743

NANPA records 13 assigned NXX blocks to rate center BURLINGTON in area code 743, 8.0% 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. 9 holders hold those blocks, the largest being ONVOY, LLC - NC (3), BANDWIDTH.COM CLEC, LLC - NC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (2). The earliest assignment on record here is 2020-04-30 and the most recent 2026-09-21. 13 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 254, 262, 304, 307 – overlay codes cover the same geography, so a rate center is served by all of them.
