MONROEVL prefixes in area code 251

NANPA records 8 assigned NXX blocks to rate center MONROEVL in area code 251, 1.5% of the 528 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (2), FRONTIER COMMUNICATIONS OF THE SOUTH, LLC - AL (2), FRACTEL, LLC (1). The earliest assignment on record here is 2020-06-11 and the most recent 2021-07-27. 5 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 260, 419, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
