MELVIN prefixes in area code 251

NANPA records 5 assigned NXX blocks to rate center MELVIN in area code 251, 0.9% 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - AL (3), NUSO, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2012-03-13 and the most recent 2020-09-11. 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 217, 325, 447, 712 – overlay codes cover the same geography, so a rate center is served by all of them.
