SEAFORD prefixes in area code 302

NANPA records 9 assigned NXX blocks to rate center SEAFORD in area code 302, 1.4% 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (3), ONVOY, LLC - DE (2), VERIZON DELAWARE, INC. (2). The earliest assignment on record here is 2016-11-23 and the most recent 2024-02-29. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
