HILLIARD prefixes in area code 904

NANPA records 6 assigned NXX blocks to rate center HILLIARD in area code 904, 0.8% 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 WINDSTREAM FLORIDA, INC. (2), TELNYX LLC (1), ONVOY, LLC - FL (1). The earliest assignment on record here is 2011-11-15 and the most recent 2025-04-18. 6 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 380, 614 – overlay codes cover the same geography, so a rate center is served by all of them.
