HARRINGTON prefixes in area code 302

NANPA records 7 assigned NXX blocks to rate center HARRINGTON in area code 302, 1.1% 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 ONVOY, LLC - DE (2), PAETEC ITEL, LLC (2), VERIZON DELAWARE, INC. (1). The earliest assignment on record here is 2016-09-22 and the most recent 2021-11-04. 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 code 509 – overlay codes cover the same geography, so a rate center is served by all of them.
