DARLINGTON prefixes in area code 667
NANPA records 3 assigned NXX blocks to rate center DARLINGTON in area code 667, 0.7% of the 454 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - MD (1), FIVE9, INC. (1), CORE COMMUNICATIONS, INC.- MD (1). The earliest assignment on record here is 2018-06-04 and the most recent 2023-12-27. 3 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 410, 443, 608, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
