SODDYDAISY prefixes in area code 423

NANPA records 8 assigned NXX blocks to rate center SODDYDAISY in area code 423, 1.0% of the 764 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 BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), NEW CINGULAR WIRELESS PCS, LLC - GA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - TN (1). The earliest assignment on record here is 2018-08-30 and the most recent 2022-11-09. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
