TOPSAIL IS prefixes in area code 910

NANPA records 3 assigned NXX blocks to rate center TOPSAIL IS in area code 910, 0.4% of the 785 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. 3 holders hold those blocks, the largest being BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (1), CHARTER IP ENABLED SERVICES, LLC (1), BANDWIDTH.COM CLEC, LLC - NC (1). The earliest assignment on record here is 2007-10-08 and the most recent 2017-01-19. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
