SPRINGCITY prefixes in area code 423
NANPA records 5 assigned NXX blocks to rate center SPRINGCITY in area code 423, 0.7% 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. 4 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), TWIN LAKES COMMUNICATIONS, INC. - TN (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1). The earliest assignment on record here is 2004-10-26 and the most recent 2023-08-22. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
