SYLVA prefixes in area code 828

NANPA records 19 assigned NXX blocks to rate center SYLVA in area code 828, 2.6% of the 724 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (5), FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - NC (4), LEVEL 3 COMMUNICATIONS, LLC - NC (2). The earliest assignment on record here is 2001-04-19 and the most recent 2021-03-23. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
