ALEXANDRIA prefixes in area code 859

NANPA records 10 assigned NXX blocks to rate center ALEXANDRIA in area code 859, 1.8% of the 563 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. 7 holders hold those blocks, the largest being CINCINNATI BELL (3), LEVEL 3 COMMUNICATIONS, LLC - KY (2), NUSO, LLC (1). The earliest assignment on record here is 2001-01-07 and the most recent 2020-08-28. 9 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 220, 318, 320, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
