ADMSCDARHL prefixes in area code 615

NANPA records 3 assigned NXX blocks to rate center ADMSCDARHL in area code 615, 0.4% of the 781 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 - TN (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2006-03-09 and the most recent 2018-05-04. 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 code 629 – overlay codes cover the same geography, so a rate center is served by all of them.
