EAST BANK prefixes in area code 681

NANPA records 3 assigned NXX blocks to rate center EAST BANK in area code 681, 0.6% of the 499 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 CSC VOICE, LLC (1), COMMIO, LLC (1), ONVOY, LLC - WV (1). The earliest assignment on record here is 2020-11-24 and the most recent 2023-09-15. 3 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 code 304 – overlay codes cover the same geography, so a rate center is served by all of them.
