HILTONHEAD prefixes in area code 854

NANPA records 16 assigned NXX blocks to rate center HILTONHEAD in area code 854, 8.8% 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (13), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (1), LEVEL 3 COMMUNICATIONS, LLC - SC (1). The earliest assignment on record here is 2022-01-12 and the most recent 2026-07-21. 16 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 843 – overlay codes cover the same geography, so a rate center is served by all of them.
