SUMMERVL prefixes in area code 854

NANPA records 9 assigned NXX blocks to rate center SUMMERVL in area code 854, 4.9% of the 182 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. 6 holders hold those blocks, the largest being ONVOY, LLC - SC (4), STRATUS NETWORKS (1), COMMIO, LLC (1). The earliest assignment on record here is 2015-09-28 and the most recent 2026-07-24. 9 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 706, 762, 814, 843 – overlay codes cover the same geography, so a rate center is served by all of them.
