SUMMERSVL prefixes in area code 304

NANPA records 8 assigned NXX blocks to rate center SUMMERSVL in area code 304, 1.0% 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. 5 holders hold those blocks, the largest being UNITED STATES CELLULAR - WV (3), FRONTIER WEST VIRGINIA INC. (2), NORTH COUNTY COMMUNICATION CORPORATION - CA (1). The earliest assignment on record here is 2021-10-11 and the most recent 2021-10-11. 5 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 417, 681 – overlay codes cover the same geography, so a rate center is served by all of them.
