HOLLY OAK prefixes in area code 302

NANPA records 23 assigned NXX blocks to rate center HOLLY OAK in area code 302, 3.5% of the 656 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. 9 holders hold those blocks, the largest being VERIZON DELAWARE, INC. (7), PAETEC ITEL, LLC (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4). The earliest assignment on record here is 2001-03-27 and the most recent 2023-09-01. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
